Cake\Datasource\ResultSetInterfaceRuntimeExceptionandHaving(Cake\Database\ExpressionInterfaceClosure|array|string $conditions, array<string, string> $types = []): $this
Connects any previously defined set of conditions to the provided list using the AND operator in the HAVING clause. This method operates in exactly the same way as the method andWhere() does. Please refer to its documentation for an insight on how to using each parameter.
Having fields are not suitable for use with user supplied data as they are not sanitized by the query builder.
Cake\Database\ExpressionInterfaceClosure|array|string $conditions The AND conditions for HAVING.
array<string, string> $types optional Associative array of type names used to bind values to query
$thisandWhere(Cake\Database\ExpressionInterfaceClosure|array|string $conditions, array $types = []): $this
Connects any previously defined set of conditions to the provided list using the AND operator. {@see \Cake\Database\Query::andWhere()}
It is important to notice that when calling this function, any previous set of conditions defined for this query will be treated as a single argument for the AND operator. This function will not only operate the most recently defined condition, but all the conditions as a whole.
When using an array for defining conditions, creating constraints form each array entry will use the same logic as with the where() function. This means that each array entry will be joined to the other using the AND operator, unless you nest the conditions in the array using other operator.
$query->where(['title' => 'Hello World')->andWhere(['author_id' => 1]);
Will produce:
WHERE title = 'Hello World' AND author_id = 1
$query ->where(['OR' => ['published' => false, 'published is NULL']]) ->andWhere(['author_id' => 1, 'comments_count >' => 10])
Produces:
WHERE (published = 0 OR published IS NULL) AND author_id = 1 AND comments_count > 10
$query
->where(['title' => 'Foo'])
->andWhere(function ($exp, $query) {
return $exp
->or(['author_id' => 1])
->add(['author_id' => 2]);
}); Generates the following conditions:
WHERE (title = 'Foo') AND (author_id = 1 OR author_id = 2)
Cake\Database\ExpressionInterfaceClosure|array|string $conditions array $types optional $thisappend(arrayTraversable $items): Cake\Collection\CollectionInterface
Appends more rows to the result of the query.
arrayTraversable $items Cake\Collection\CollectionInterfaceapplyOptions(array<string, mixed> $options): $this
Populates or adds parts to current query clauses using an array. This is handy for passing all query clauses at once.
The method accepts the following query clause related options:
All other options will not affect the query, but will be stored as custom options that can be read via getOptions(). Furthermore they are automatically passed to Model.beforeFind.
$query->applyOptions([
'fields' => ['id', 'name'],
'conditions' => [
'created >=' => '2013-01-01'
],
'limit' => 10,
]); Is equivalent to:
$query ->select(['id', 'name']) ->where(['created >=' => '2013-01-01']) ->limit(10)
Custom options can be read via getOptions():
$query->applyOptions([ 'fields' => ['id', 'name'], 'custom' => 'value', ]);
Here $options will hold ['custom' => 'value'] (the fields option will be applied to the query instead of being stored, as it's a query clause related option):
$options = $query->getOptions();
array<string, mixed> $options The options to be applied
$thisbind(string|int $param, mixed $value, string|int|null $type = null): $this
Associates a query placeholder to a value and a type.
$query->bind(':id', 1, 'integer'); string|int $param placeholder to be replaced with quoted version of $value
mixed $value The value to be bound
string|int|null $type optional the mapped type name, used for casting when sending to database
$thiscache(Closure|string|false $key, Psr\SimpleCache\CacheInterface|string $config = 'default'): $this
Enable result caching for this query.
If a query has caching enabled, it will do the following when executed:
// Simple string key + config
$query->cache('my_key', 'db_results');
// Function to generate key.
$query->cache(function ($q) {
$key = serialize($q->clause('select'));
$key .= serialize($q->clause('where'));
return md5($key);
});
// Using a pre-built cache engine.
$query->cache('my_key', $engine);
// Disable caching
$query->cache(false); Closure|string|false $key Either the cache key or a function to generate the cache key. When using a function, this query instance will be supplied as an argument.
Psr\SimpleCache\CacheInterface|string $config optional Either the name of the cache config to use, or a cache config instance.
$thisRuntimeExceptionchunk(int $size): Cake\Collection\CollectionInterface
Groups the results in arrays of $size rows each.
int $size Cake\Collection\CollectionInterfaceclause(string $name): mixed
Returns any data that was stored in the specified clause. This is useful for modifying any internal part of the query and it is used by the SQL dialects to transform the query accordingly before it is executed. The valid clauses that can be retrieved are: delete, update, set, insert, values, select, distinct, from, join, set, where, group, having, order, limit, offset and union.
The return value for each of those parts may vary. Some clauses use QueryExpression to internally store their state, some use arrays and others may use booleans or integers. This is summary of the return types for each clause.
string $name name of the clause to be returned
mixedInvalidArgumentExceptioncleanCopy(): static
Creates a copy of this current query, triggers beforeFind and resets some state.
The following state will be cleared:
This method creates query clones that are useful when working with subqueries.
staticclearContain(): $this
Clears the contained associations from the current query.
$thisclearResult(): $this
Clears the internal result cache and the internal count value from the current query object.
$thiscombine(mixed $k, mixed $v, mixed $g = null): Cake\Collection\CollectionInterface
Returns the values of the column $v index by column $k, and grouped by $g.
Cake\Collection\CollectionInterfacecontain(array|string $associations, callable|bool $override = false): $this
Sets the list of associations that should be eagerly loaded along with this query. The list of associated tables passed must have been previously set as associations using the Table API.
// Bring articles' author information
$query->contain('Author');
// Also bring the category and tags associated to each article
$query->contain(['Category', 'Tag']); Associations can be arbitrarily nested using dot notation or nested arrays, this allows this object to calculate joins or any additional queries that must be executed to bring the required associated data.
// Eager load the product info, and for each product load other 2 associations
$query->contain(['Product' => ['Manufacturer', 'Distributor']);
// Which is equivalent to calling
$query->contain(['Products.Manufactures', 'Products.Distributors']);
// For an author query, load his region, state and country
$query->contain('Regions.States.Countries'); It is possible to control the conditions and fields selected for each of the contained associations:
$query->contain(['Tags' => function ($q) {
return $q->where(['Tags.is_popular' => true]);
}]);
$query->contain(['Products.Manufactures' => function ($q) {
return $q->select(['name'])->where(['Manufactures.active' => true]);
}]); Each association might define special options when eager loaded, the allowed options that can be set per association are:
foreignKey: Used to set a different field to match both tables, if set to false no join conditions will be generated automatically. false can only be used on joinable associations and cannot be used with hasMany or belongsToMany associations.fields: An array with the fields that should be fetched from the association.finder: The finder to use when loading associated records. Either the name of the finder as a string, or an array to define options to pass to the finder.queryBuilder: Equivalent to passing a callable instead of an options array.// Set options for the hasMany articles that will be eagerly loaded for an author
$query->contain([
'Articles' => [
'fields' => ['title', 'author_id']
]
]); Finders can be configured to use options.
// Retrieve translations for the articles, but only those for the `en` and `es` locales
$query->contain([
'Articles' => [
'finder' => [
'translations' => [
'locales' => ['en', 'es']
]
]
]
]); When containing associations, it is important to include foreign key columns. Failing to do so will trigger exceptions.
// Use a query builder to add conditions to the containment
$query->contain('Authors', function ($q) {
return $q->where(...); // add conditions
});
// Use special join conditions for multiple containments in the same method call
$query->contain([
'Authors' => [
'foreignKey' => false,
'queryBuilder' => function ($q) {
return $q->where(...); // Add full filtering conditions
}
],
'Tags' => function ($q) {
return $q->where(...); // add conditions
}
]); If called with an empty first argument and $override is set to true, the previous list will be emptied.
array|string $associations List of table aliases to be queried.

callable|string $field Cake\Collection\CollectionInterfacecounter(callable|null $counter): $this
Registers a callable function that will be executed when the count method in this query is called. The return value for the function will be set as the return value of the count method.
This is particularly useful when you need to optimize a query for returning the count, for example removing unnecessary joins, removing group by or just return an estimated number of rows.
The callback will receive as first argument a clone of this query and not this query itself.
If the first param is a null value, the built-in counter function will be called instead
callable|null $counter The counter value
$thisdecorateResults(callable|null $callback, bool $overwrite = false): $this
Registers a callback to be executed for each result that is fetched from the result set, the callback function will receive as first parameter an array with the raw data from the database for every row that is fetched and must return the row with any possible modifications.
Callbacks will be executed lazily, if only 3 rows are fetched for database it will called 3 times, event though there might be more rows to be fetched in the cursor.
Callbacks are stacked in the order they are registered, if you wish to reset the stack the call this function with the second parameter set to true.
If you wish to remove all decorators from the stack, set the first parameter to null and the second to true.
$query->decorateResults(function ($row) {
$row['order_total'] = $row['subtotal'] + ($row['subtotal'] * $row['tax']);
return $row;
}); callable|null $callback The callback to invoke when results are fetched.
bool $overwrite optional Whether this should append or replace all existing decorators.
$thisdelete(string|null $table = null): $this
Create a delete query.
This changes the query type to be 'delete'. Can be combined with the where() method to create delete queries.
string|null $table optional Unused parameter.
$thisdisableAutoFields(): $this
Disables automatically appending fields.
$thisdisableBufferedResults(): $this
Disables buffered results.
Disabling buffering will consume less memory as fetched results are not remembered for future iterations.
$thisdisableHydration(): $this
Disable hydrating entities.
Disabling hydration will cause array results to be returned for the query instead of entities.
$thisdisableResultsCasting(): $this
Disables result casting.
When disabled, the fields will be returned as received from the database driver (which in most environments means they are being returned as strings), which can improve performance with larger datasets.
$thisdistinct(Cake\Database\ExpressionInterface|array|string|bool $on = [], bool $overwrite = false): $this
Adds a DISTINCT clause to the query to remove duplicates from the result set. This clause can only be used for select statements.
If you wish to filter duplicates based of those rows sharing a particular field or set of fields, you may pass an array of fields to filter on. Beware that this option might not be fully supported in all database systems.
// Filters products with the same name and city
$query->select(['name', 'city'])->from('products')->distinct();
// Filters products in the same city
$query->distinct(['city']);
$query->distinct('city');
// Filter products with the same name
$query->distinct(['name'], true);
$query->distinct('name', true); Cake\Database\ExpressionInterface|array|string|bool $on optional Enable/disable distinct class or list of fields to be filtered on
bool $overwrite optional whether to reset fields with passed list or not
$thiseach(callable $c): Cake\Collection\CollectionInterface
Passes each of the query results to the callable
callable $c Cake\Collection\CollectionInterfaceeagerLoaded(bool $value): $this

bool $value Whether to eager load.
$thisenableAutoFields(bool $value = true): $this
Sets whether the ORM should automatically append fields.
By default calling select() will disable auto-fields. You can re-enable auto-fields with this method.
bool $value optional Set true to enable, false to disable.
$thisenableBufferedResults(bool $enable = true): $this
Enables/Disables buffered results.
When enabled the results returned by this Query will be buffered. This enables you to iterate a result set multiple times, or both cache and iterate it.
When disabled it will consume less memory as fetched results are not remembered for future iterations.
bool $enable optional Whether to enable buffering
$thisenableHydration(bool $enable = true): $this
Toggle hydrating entities.
If set to false array results will be returned for the query.
bool $enable optional Use a boolean to set the hydration mode.
$thisenableResultsCasting(): $this
Enables result casting.
When enabled, the fields in the results returned by this Query will be cast to their corresponding PHP data type.
$thisepilog(Cake\Database\ExpressionInterface|string|null $expression = null): $this

$query->select('id')->where(['author_id' => 1])->epilog('FOR UPDATE');
$query
->insert('articles', ['title'])
->values(['author_id' => 1])
->epilog('RETURNING id'); Epliog content is raw SQL and not suitable for use with user supplied data.
Cake\Database\ExpressionInterface|string|null $expression optional The expression to be appended
$thisevery(callable $c): bool
Returns true if all the results pass the callable test
callable $c boolexecute(): Cake\Database\StatementInterface
Compiles the SQL representation of this query and executes it using the configured connection object. Returns the resulting statement object.
Executing a query internally executes several steps, the first one is letting the connection transform this object to fit its particular dialect, this might result in generating a different Query object that will be the one to actually be executed. Immediately after, literal values are passed to the connection so they are bound to the query in a safe way. Finally, the resulting statement is decorated with custom objects to execute callbacks for each row retrieved if necessary.
Resulting statement is traversable, so it can be used in any loop as you would with an array.
This method can be overridden in query subclasses to decorate behavior around query execution.
Cake\Database\StatementInterfaceexpr(Cake\Database\ExpressionInterface|array|string|null $rawExpression = null): Cake\Database\Expression\QueryExpression
Returns a new QueryExpression object. This is a handy function when building complex queries using a fluent interface. You can also override this function in subclasses to use a more specialized QueryExpression class if required.
You can optionally pass a single raw SQL string or an array or expressions in any format accepted by \Cake\Database\Expression\QueryExpression:
$expression = $query->expr(); // Returns an empty expression object
$expression = $query->expr('Table.column = Table2.column'); // Return a raw SQL expression Cake\Database\ExpressionInterface|array|string|null $rawExpression optional A string, array or anything you want wrapped in an expression object
Cake\Database\Expression\QueryExpressionextract(mixed $field): Cake\Collection\CollectionInterface

Keeps the results using passing the callable test
callable $c optional Cake\Collection\CollectionInterfacefind(string $finder, array<string, mixed> $options = []): static
Apply custom finds to against an existing query object.
Allows custom find methods to be combined and applied to each other.
$repository->find('all')->find('recent'); The above is an example of stacking multiple finder methods onto a single query.
string $finder The finder method to use.
array<string, mixed> $options optional The options for the finder.
staticfirst(): Cake\Datasource\EntityInterface|array|null
Returns the first result out of executing this query, if the query has not been executed before, it will set the limit clause to 1 for performance reasons.
$singleUser = $query->select(['id', 'username'])->first();
Cake\Datasource\EntityInterface|array|nullfirstOrFail(): Cake\Datasource\EntityInterface|array
Get the first result from the executing query or raise an exception.
Cake\Datasource\EntityInterface|arrayCake\Datasource\Exception\RecordNotFoundExceptionformatResults(callable|null $formatter = null, int|bool $mode = self::APPEND): $this
Registers a new formatter callback function that is to be executed when trying to fetch the results from the database.
If the second argument is set to true, it will erase previous formatters and replace them with the passed first argument.
Callbacks are required to return an iterator object, which will be used as the return value for this query's result. Formatter functions are applied after all the MapReduce routines for this query have been executed.
Formatting callbacks will receive two arguments, the first one being an object implementing \Cake\Collection\CollectionInterface, that can be traversed and modified at will. The second one being the query instance on which the formatter callback is being applied.
Usually the query instance received by the formatter callback is the same query instance on which the callback was attached to, except for in a joined association, in that case the callback will be invoked on the association source side query, and it will receive that query instance instead of the one on which the callback was originally attached to - see the examples below!
Return all results from the table indexed by id:
$query->select(['id', 'name'])->formatResults(function ($results) {
return $results->indexBy('id');
}); Add a new column to the ResultSet:
$query->select(['name', 'birth_date'])->formatResults(function ($results) {
return $results->map(function ($row) {
$row['age'] = $row['birth_date']->diff(new DateTime)->y;
return $row;
});
}); Add a new column to the results with respect to the query's hydration configuration:
$query->formatResults(function ($results, $query) {
return $results->map(function ($row) use ($query) {
$data = [
'bar' => 'baz',
];
if ($query->isHydrationEnabled()) {
$row['foo'] = new Foo($data)
} else {
$row['foo'] = $data;
}
return $row;
});
}); Retaining access to the association target query instance of joined associations, by inheriting the contain callback's query argument:
// Assuming a `Articles belongsTo Authors` association that uses the join strategy
$articlesQuery->contain('Authors', function ($authorsQuery) {
return $authorsQuery->formatResults(function ($results, $query) use ($authorsQuery) {
// Here `$authorsQuery` will always be the instance
// where the callback was attached to.
// The instance passed to the callback in the second
// argument (`$query`), will be the one where the
// callback is actually being applied to, in this
// example that would be `$articlesQuery`.
// ...
return $results;
});
}); callable|null $formatter optional The formatting callable.
int|bool $mode optional Whether to overwrite, append or prepend the formatter.
$thisInvalidArgumentExceptionfrom(array|string $tables = [], bool $overwrite = false): $this
Adds a single or multiple tables to be used in the FROM clause for this query. Tables can be passed as an array of strings, array of expression objects, a single expression or a single string.
If an array is passed, keys will be used to alias tables using the value as the real field to be aliased. It is possible to alias strings, ExpressionInterface objects or even other Query objects.
By default this function will append any passed argument to the list of tables to be selected from, unless the second argument is set to true.
This method can be used for select, update and delete statements.
$query->from(['p' => 'posts']); // Produces FROM posts p
$query->from('authors'); // Appends authors: FROM posts p, authors
$query->from(['products'], true); // Resets the list: FROM products
$query->from(['sub' => $countQuery]); // FROM (SELECT ...) sub array|string $tables optional tables to be added to the list. This argument, can be passed as an array of strings, array of expression objects, or a single string. See the examples above for the valid call types.
bool $overwrite optional whether to reset tables with passed list or not
$thisfunc(): Cake\Database\FunctionsBuilder

Cake\Datasource\ResultSetInterfacegetMapReducers(): array
Returns the list of previously registered map reduce routines.
arraygetOptions(): array
Returns an array with the custom options that were applied to this query and that were not already processed by another method in this class.
$query->applyOptions(['doABarrelRoll' => true, 'fields' => ['id', 'name']); $query->getOptions(); // Returns ['doABarrelRoll' => true]

Gets the TypeMap class where the types for each of the fields in the select clause are stored.
Cake\Database\TypeMapgetTypeMap(): Cake\Database\TypeMap
Returns the existing type map.
Cake\Database\TypeMapgetValueBinder(): Cake\Database\ValueBinder
Returns the currently used ValueBinder instance.
A ValueBinder is responsible for generating query placeholders and temporarily associate values to those placeholders so that they can be passed correctly to the statement object.
Cake\Database\ValueBindergroup(Cake\Database\ExpressionInterface|array|string $fields, bool $overwrite = false): $this
Adds a single or multiple fields to be used in the GROUP BY clause for this query. Fields can be passed as an array of strings, array of expression objects, a single expression or a single string.
By default this function will append any passed argument to the list of fields to be grouped, unless the second argument is set to true.

Cake\Database\ExpressionInterfaceClosure|array|string|null $conditions optional The having conditions.
array<string, string> $types optional Associative array of type names used to bind values to query
bool $overwrite optional whether to reset conditions with passed list or not
$thisidentifier(string $identifier): Cake\Database\ExpressionInterface
Creates an expression that refers to an identifier. Identifiers are used to refer to field names and allow the SQL compiler to apply quotes or escape the identifier.
The value is used as is, and you might be required to use aliases or include the table reference in the identifier. Do not use this method to inject SQL methods or logical statements.
$query->newExpr()->lte('count', $query->identifier('total')); string $identifier The identifier for an expression
Cake\Database\ExpressionInterfaceindexBy(callable|string $callback): Cake\Collection\CollectionInterface
Returns the results indexed by the value of a column.
callable|string $callback Cake\Collection\CollectionInterfaceinnerJoin(array<string, mixed>|string $table, Cake\Database\ExpressionInterface|array|string $conditions = [], array<string, string> $types = []): $this
Adds a single INNER JOIN clause to the query.
This is a shorthand method for building joins via join().
The arguments of this method are identical to the leftJoin() shorthand, please refer to that method's description for further details.
array<string, mixed>|string $table The table to join with
Cake\Database\ExpressionInterface|array|string $conditions optional The conditions to use for joining.
array<string, string> $types optional a list of types associated to the conditions used for converting values to the corresponding database representation.
$thisinnerJoinWith(string $assoc, callable|null $builder = null): $this
Creates an INNER JOIN with the passed association table while preserving the foreign key matching and the custom conditions that were originally set for it.
This function will add entries in the contain graph.
// Bring only articles that were tagged with 'cake'
$query->innerJoinWith('Tags', function ($q) {
return $q->where(['name' => 'cake']);
}); This will create the following SQL:
SELECT Articles.* FROM articles Articles INNER JOIN tags Tags ON Tags.name = 'cake' INNER JOIN articles_tags ArticlesTags ON ArticlesTags.tag_id = Tags.id AND ArticlesTags.articles_id = Articles.id
This function works the same as matching() with the difference that it will select no fields from the association.
string $assoc The association to join with
callable|null $builder optional a function that will receive a pre-made query object that can be used to add custom conditions or selecting some fields
$thisinsert(array $columns, array<int|string, string> $types = []): $this
Create an insert query.
This changes the query type to be 'insert'. Note calling this method will reset any data previously set with Query::values()
Can be combined with the where() method to create delete queries.

By default calling select() will disable auto-fields. You can re-enable auto-fields with enableAutoFields().
bool|nullisBufferedResultsEnabled(): bool
Returns whether buffered results are enabled/disabled.
When enabled the results returned by this Query will be buffered. This enables you to iterate a result set multiple times, or both cache and iterate it.
When disabled it will consume less memory as fetched results are not remembered for future iterations.
boolisEagerLoaded(): bool
Returns the current configured query _eagerLoaded value
boolisEmpty(): bool
Returns true if this query found no results.
boolisHydrationEnabled(): bool
Returns the current hydration mode.
boolisResultsCastingEnabled(): bool
Returns whether result casting is enabled/disabled.
When enabled, the fields in the results returned by this Query will be casted to their corresponding PHP data type.
When disabled, the fields will be returned as received from the database driver (which in most environments means they are being returned as strings), which can improve performance with larger datasets.
booljoin(array<string, mixed>|string $tables, array<string, string> $types = [], bool $overwrite = false): $this
Adds a single or multiple tables to be used as JOIN clauses to this query. Tables can be passed as an array of strings, an array describing the join parts, an array with multiple join descriptions, or a single string.
By default this function will append any passed argument to the list of tables to be joined, unless the third argument is set to true.
When no join type is specified an INNER JOIN is used by default: $query->join(['authors']) will produce INNER JOIN authors ON 1 = 1
It is also possible to alias joins using the array key: $query->join(['a' => 'authors']) will produce INNER JOIN authors a ON 1 = 1
A join can be fully described and aliased using the array notation:
$query->join([
'a' => [
'table' => 'authors',
'type' => 'LEFT',
'conditions' => 'a.id = b.author_id'
]
]);
// Produces LEFT JOIN authors a ON a.id = b.author_id You can even specify multiple joins in an array, including the full description:
$query->join([
'a' => [
'table' => 'authors',
'type' => 'LEFT',
'conditions' => 'a.id = b.author_id'
],
'p' => [
'table' => 'publishers',
'type' => 'INNER',
'conditions' => 'p.id = b.publisher_id AND p.name = "Cake Software Foundation"'
]
]);
// LEFT JOIN authors a ON a.id = b.author_id
// INNER JOIN publishers p ON p.id = b.publisher_id AND p.name = "Cake Software Foundation" Conditions can be expressed, as in the examples above, using a string for comparing columns, or string with already quoted literal values. Additionally it is possible to use conditions expressed in arrays or expression objects.
When using arrays for expressing conditions, it is often desirable to convert the literal values to the correct database representation. This is achieved using the second parameter of this function.
$query->join(['a' => [
'table' => 'articles',
'conditions' => [
'a.posted >=' => new DateTime('-3 days'),
'a.published' => true,
'a.author_id = authors.id'
]
]], ['a.posted' => 'datetime', 'a.published' => 'boolean']) When creating aliased joins using the array notation, you can override previous join definitions by using the same alias in consequent calls to this function or you can replace all previously defined joins with another list if the third parameter for this function is set to true.
$query->join(['alias' => 'table']); // joins table with as alias $query->join(['alias' => 'another_table']); // joins another_table with as alias $query->join(['something' => 'different_table'], [], true); // resets joins list
array<string, mixed>|string $tables list of tables to be joined in the query

Return the last row of the query result
mixedleftJoin(array<string, mixed>|string $table, Cake\Database\ExpressionInterface|array|string $conditions = [], array $types = []): $this
Adds a single LEFT JOIN clause to the query.
This is a shorthand method for building joins via join().
The table name can be passed as a string, or as an array in case it needs to be aliased:
// LEFT JOIN authors ON authors.id = posts.author_id
$query->leftJoin('authors', 'authors.id = posts.author_id');
// LEFT JOIN authors a ON a.id = posts.author_id
$query->leftJoin(['a' => 'authors'], 'a.id = posts.author_id'); Conditions can be passed as strings, arrays, or expression objects. When using arrays it is possible to combine them with the $types parameter in order to define how to convert the values:
$query->leftJoin(['a' => 'articles'], [
'a.posted >=' => new DateTime('-3 days'),
'a.published' => true,
'a.author_id = authors.id'
], ['a.posted' => 'datetime', 'a.published' => 'boolean']); See join() for further details on conditions and types.
array<string, mixed>|string $table The table to join with
Cake\Database\ExpressionInterface|array|string $conditions optional The conditions to use for joining.
array $types optional a list of types associated to the conditions used for converting values to the corresponding database representation.
$thisleftJoinWith(string $assoc, callable|null $builder = null): $this
Creates a LEFT JOIN with the passed association table while preserving the foreign key matching and the custom conditions that were originally set for it.
This function will add entries in the contain graph.
// Get the count of articles per user
$usersQuery
->select(['total_articles' => $query->func()->count('Articles.id')])
->leftJoinWith('Articles')
->group(['Users.id'])
->enableAutoFields(); You can also customize the conditions passed to the LEFT JOIN:
// Get the count of articles per user with at least 5 votes
$usersQuery
->select(['total_articles' => $query->func()->count('Articles.id')])
->leftJoinWith('Articles', function ($q) {
return $q->where(['Articles.votes >=' => 5]);
})
->group(['Users.id'])
->enableAutoFields(); This will create the following SQL:
SELECT COUNT(Articles.id) AS total_articles, Users.* FROM users Users LEFT JOIN articles Articles ON Articles.user_id = Users.id AND Articles.votes >= 5 GROUP BY USers.id
It is possible to left join deep associations by using dot notation
// Total comments in articles by 'markstory'
$query
->select(['total_comments' => $query->func()->count('Comments.id')])
->leftJoinWith('Comments.Users', function ($q) {
return $q->where(['username' => 'markstory']);
})
->group(['Users.id']); Please note that the query passed to the closure will only accept calling select, where, andWhere and orWhere on it. If you wish to add more complex clauses you can do it directly in the main query.
string $assoc The association to join with
callable|null $builder optional a function that will receive a pre-made query object that can be used to add custom conditions or selecting some fields
$thislimit(Cake\Database\ExpressionInterface|int|null $limit): $this
Sets the number of records that should be retrieved from database, accepts an integer or an expression object that evaluates to an integer. In some databases, this operation might not be supported or will require the query to be transformed in order to limit the result set size.
$query->limit(10) // generates LIMIT 10 $query->limit($query->newExpr()->add(['1 + 1'])); // LIMIT (1 + 1)
Cake\Database\ExpressionInterface|int|null $limit number of records to be returned

The MapReduce routing will only be run when the query is executed and the first result is attempted to be fetched.
If the third argument is set to true, it will erase previous map reducers and replace it with the arguments passed.
callable|null $mapper optional The mapper callable.
callable|null $reducer optional The reducing function.
bool $overwrite optional Set to true to overwrite existing map + reduce functions.
$thismatching(string $assoc, callable|null $builder = null): $this
Adds filtering conditions to this query to only bring rows that have a relation to another from an associated table, based on conditions in the associated table.
This function will add entries in the contain graph.
// Bring only articles that were tagged with 'cake'
$query->matching('Tags', function ($q) {
return $q->where(['name' => 'cake']);
}); It is possible to filter by deep associations by using dot notation:
// Bring only articles that were commented by 'markstory'
$query->matching('Comments.Users', function ($q) {
return $q->where(['username' => 'markstory']);
}); As this function will create INNER JOIN, you might want to consider calling distinct on this query as you might get duplicate rows if your conditions don't filter them already. This might be the case, for example, of the same user commenting more than once in the same article.
// Bring unique articles that were commented by 'markstory'
$query->distinct(['Articles.id'])
->matching('Comments.Users', function ($q) {
return $q->where(['username' => 'markstory']);
}); Please note that the query passed to the closure will only accept calling select, where, andWhere and orWhere on it. If you wish to add more complex clauses you can do it directly in the main query.

By default this function will append any passed argument to the list of modifiers to be applied, unless the second argument is set to true.
// Ignore cache query in MySQL
$query->select(['name', 'city'])->from('products')->modifier('SQL_NO_CACHE');
// It will produce the SQL: SELECT SQL_NO_CACHE name, city FROM products
// Or with multiple modifiers
$query->select(['name', 'city'])->from('products')->modifier(['HIGH_PRIORITY', 'SQL_NO_CACHE']);
// It will produce the SQL: SELECT HIGH_PRIORITY SQL_NO_CACHE name, city FROM products Cake\Database\ExpressionInterface|array|string $modifiers modifiers to be applied to the query
bool $overwrite optional whether to reset order with field list or not
$thisnest(mixed $k, mixed $p, mixed $n = 'children'): Cake\Collection\CollectionInterface

This function will add entries in the contain graph.
// Bring only articles that were not tagged with 'cake'
$query->notMatching('Tags', function ($q) {
return $q->where(['name' => 'cake']);
}); It is possible to filter by deep associations by using dot notation:
// Bring only articles that weren't commented by 'markstory'
$query->notMatching('Comments.Users', function ($q) {
return $q->where(['username' => 'markstory']);
}); As this function will create a LEFT JOIN, you might want to consider calling distinct on this query as you might get duplicate rows if your conditions don't filter them already. This might be the case, for example, of the same article having multiple comments.
// Bring unique articles that were commented by 'markstory'
$query->distinct(['Articles.id'])
->notMatching('Comments.Users', function ($q) {
return $q->where(['username' => 'markstory']);
}); Please note that the query passed to the closure will only accept calling select, where, andWhere and orWhere on it. If you wish to add more complex clauses you can do it directly in the main query.

Sets the number of records that should be skipped from the original result set This is commonly used for paginating large results. Accepts an integer or an expression object that evaluates to an integer.
In some databases, this operation might not be supported or will require the query to be transformed in order to limit the result set size.
$query->offset(10) // generates OFFSET 10 $query->offset($query->newExpr()->add(['1 + 1'])); // OFFSET (1 + 1)
Cake\Database\ExpressionInterface|int|null $offset number of records to be skipped
$thisorder(Cake\Database\ExpressionInterfaceClosure|array|string $fields, bool $overwrite = false): $this
Adds a single or multiple fields to be used in the ORDER clause for this query. Fields can be passed as an array of strings, array of expression objects, a single expression or a single string.
If an array is passed, keys will be used as the field itself and the value will represent the order in which such field should be ordered. When called multiple times with the same fields as key, the last order definition will prevail over the others.
By default this function will append any passed argument to the list of fields to be selected, unless the second argument is set to true.
$query->order(['title' => 'DESC', 'author_id' => 'ASC']);
Produces:
ORDER BY title DESC, author_id ASC
$query
->order(['title' => $query->newExpr('DESC NULLS FIRST')])
->order('author_id'); Will generate:
ORDER BY title DESC NULLS FIRST, author_id
$expression = $query->newExpr()->add(['id % 2 = 0']); $query->order($expression)->order(['title' => 'ASC']);
Will become:
ORDER BY (id %2 = 0), title ASC
If you need to set complex expressions as order conditions, you should use orderAsc() or orderDesc().
Cake\Database\ExpressionInterfaceClosure|array|string $fields fields to be added to the list
bool $overwrite optional whether to reset order with field list or not
$thisorderAsc(Cake\Database\ExpressionInterfaceClosure|string $field, bool $overwrite = false): $this

Cake\Database\ExpressionInterface|array|string $conditions optional The conditions to use for joining.
array $types optional a list of types associated to the conditions used for converting values to the corresponding database representation.
$thisrowCountAndClose(): int
Executes the SQL of this query and immediately closes the statement before returning the row count of records changed.
This method can be used with UPDATE and DELETE queries, but is not recommended for SELECT queries and is not used to count records.
$rowCount = $query->update('articles')
->set(['published'=>true])
->where(['published'=>false])
->rowCountAndClose(); The above example will change the published column to true for all false records, and return the number of records that were updated.
intsample(int $size = 10): Cake\Collection\CollectionInterface
In-memory shuffle the results and return a subset of them.
int $size optional Cake\Collection\CollectionInterfaceselect(Cake\Database\ExpressionInterface|callable|array|string $fields = [], bool $overwrite = false): $this
Adds new fields to be returned by a SELECT statement when this query is executed. Fields can be passed as an array of strings, array of expression objects, a single expression or a single string.
If an array is passed, keys will be used to alias fields using the value as the real field to be aliased. It is possible to alias strings, Expression objects or even other Query objects.
If a callable function is passed, the returning array of the function will be used as the list of fields.
By default this function will append any passed argument to the list of fields to be selected, unless the second argument is set to true.
$query->select(['id', 'title']); // Produces SELECT id, title
$query->select(['author' => 'author_id']); // Appends author: SELECT id, title, author_id as author
$query->select('id', true); // Resets the list: SELECT id
$query->select(['total' => $countQuery]); // SELECT id, (SELECT ...) AS total
$query->select(function ($query) {
return ['article_id', 'total' => $query->count('*')];
}) By default no fields are selected, if you have an instance of Cake\ORM\Query and try to append fields you should also call Cake\ORM\Query::enableAutoFields() to select the default fields from the table.
If you pass an instance of a Cake\ORM\Table or Cake\ORM\Association class, all the fields in the schema of the table or the association will be added to the select clause.

The callback will receive 2 parameters, the first one is the value of the query part that is being iterated and the second the name of such part.
$query->select(['title'])->from('articles')->traverse(function ($value, $clause) {
if ($clause === 'select') {
var_dump($value);
}
}); callable $callback A function or callable to be executed for each part
$thistraverseExpressions(callable $callback): $this

This will execute the provided callback function for each ExpressionInterface object that is stored inside this query at any nesting depth in any part of the query.
Callback will receive as first parameter the currently visited expression.
callable $callback the function to be executed for each ExpressionInterface found inside this query.
$thistraverseParts(callable $visitor, array<string> $parts): $this
Will iterate over the provided parts.
Traversing functions can aggregate results using variables in the closure or instance variables. This method can be used to traverse a subset of query parts in order to render a SQL query.
The callback will receive 2 parameters, the first one is the value of the query part that is being iterated and the second the name of such part.
$query->select(['title'])->from('articles')->traverse(function ($value, $clause) {
if ($clause === 'select') {

stringunion(Cake\Database\Query|string $query, bool $overwrite = false): $this
Adds a complete query to be used in conjunction with an UNION operator with this query. This is used to combine the result set of this query with the one that will be returned by the passed query. You can add as many queries as you required by calling multiple times this method with different queries.
By default, the UNION operator will remove duplicate rows, if you wish to include every row for all queries, use unionAll().
$union = (new Query($conn))->select(['id', 'title'])->from(['a' => 'articles']); $query->select(['id', 'name'])->from(['d' => 'things'])->union($union);
Will produce:
SELECT id, name FROM things d UNION SELECT id, title FROM articles a
Cake\Database\Query|string $query full SQL query to be used in UNION operator
bool $overwrite optional whether to reset the list of queries to be operated or not
$thisunionAll(Cake\Database\Query|string $query, bool $overwrite = false): $this
Adds a complete query to be used in conjunction with the UNION ALL operator with this query. This is used to combine the result set of this query with the one that will be returned by the passed query. You can add as many queries as you required by calling multiple times this method with different queries.
Unlike UNION, UNION ALL will not remove duplicate rows.
$union = (new Query($conn))->select(['id', 'title'])->from(['a' => 'articles']); $query->select(['id', 'name'])->from(['d' => 'things'])->unionAll($union);
Will produce:
SELECT id, name FROM things d UNION ALL SELECT id, title FROM articles a
Cake\Database\Query|string $query full SQL query to be used in UNION operator
bool $overwrite optional whether to reset the list of queries to be operated or not
$thisupdate(Cake\Database\ExpressionInterface|string $table = null): $this
Create an update query.
This changes the query type to be 'update'. Can be combined with set() and where() methods to create update queries.
Cake\Database\ExpressionInterface|string $table optional Unused parameter.
$thisvalues(Cake\Database\Expression\ValuesExpressionCake\Database\Query|array $data): $this
Set the values for an insert query.
Multi inserts can be performed by calling values() more than one time, or by providing an array of value sets. Additionally $data can be a Query instance to insert data from another SELECT statement.
Cake\Database\Expression\ValuesExpressionCake\Database\Query|array $data The data to insert.
$thisCake\Database\Exception\DatabaseExceptionwhere(Cake\Database\ExpressionInterfaceClosure|array|string|null $conditions = null, array<string, string> $types = [], bool $overwrite = false): $this
Adds a condition or set of conditions to be used in the WHERE clause for this query. Conditions can be expressed as an array of fields as keys with comparison operators in it, the values for the array will be used for comparing the field to such literal. Finally, conditions can be expressed as a single string or an array of strings.
When using arrays, each entry will be joined to the rest of the conditions using an AND operator. Consecutive calls to this function will also join the new conditions specified using the AND operator. Additionally, values can be expressed using expression objects which can include other query objects.
Any conditions created with this methods can be used with any SELECT, UPDATE and DELETE type of queries.
$query->where([
'posted >=' => new DateTime('3 days ago'),
'title LIKE' => 'Hello W%',
'author_id' => 1,
], ['posted' => 'datetime']); The previous example produces:
WHERE posted >= 2012-01-27 AND title LIKE 'Hello W%' AND author_id = 1
Second parameter is used to specify what type is expected for each passed key. Valid types can be used from the mapped with Database\Type class.
$query->where([
'author_id !=' => 1,
'OR' => ['published' => true, 'posted <' => new DateTime('now')],
'NOT' => ['title' => 'Hello']
], ['published' => boolean, 'posted' => 'datetime'] The previous example produces:
WHERE author_id = 1 AND (published = 1 OR posted < '2012-02-01') AND NOT (title = 'Hello')
You can nest conditions using conjunctions as much as you like. Sometimes, you may want to define 2 different options for the same key, in that case, you can wrap each condition inside a new array:
$query->where(['OR' => [['published' => false], ['published' => true]])
Keep in mind that every time you call where() with the third param set to false (default), it will join the passed conditions to the previous stored list using the AND operator. Also, using the same array key twice in consecutive calls to this method will not override the previous value.
$exp = $query->newExpr()->add(['id !=' => 100, 'author_id' != 1])->tieWith('OR');
$query->where(['published' => true], ['published' => 'boolean'])->where($exp); The previous example produces:
WHERE (id != 100 OR author_id != 1) AND published = 1
Other Query objects that be used as conditions for any field.
You can use callable functions to construct complex expressions, functions receive as first argument a new QueryExpression object and this query instance as second argument. Functions must return an expression object, that will be added the list of conditions for the query using the AND operator.
$query
->where(['title !=' => 'Hello World'])
->where(function ($exp, $query) {
$or = $exp->or(['id' => 1]);
$and = $exp->and(['id >' => 2, 'id <' => 10]);
return $or->add($and);
}); WHERE title != 'Hello World' AND (id = 1 OR (id > 2 AND id < 10))
$query->where(['articles.author_id = authors.id', 'modified IS NULL']);
The previous example produces:
WHERE articles.author_id = authors.id AND modified IS NULL
Please note that when using the array notation or the expression objects, all values will be correctly quoted and transformed to the correspondent database data type automatically for you, thus securing your application from SQL injections. If you use string conditions make sure that your values are correctly quoted. The safest thing you can do is to never use string conditions.
