Method Details

addForeignKey() public method

Builds a SQL statement for adding a foreign key constraint to an existing table.

The method will properly quote the table and column names.

public string addForeignKey ( $name, $table, $columns, $refTable, $refColumns, $delete = null, $update = null )
$name	string	The name of the foreign key constraint.
$table	string	The table that the foreign key constraint will be added to.
$columns	string\|array	The name of the column to that the constraint will be added on. If there are multiple columns, separate them with commas or use an array to represent them.
$refTable	string	The table that the foreign key references to.
$refColumns	string\|array	The name of the column that the foreign key references to. If there are multiple columns, separate them with commas or use an array to represent them.
$delete	string	The ON DELETE option. Most DBMS support these options: RESTRICT, CASCADE, NO ACTION, SET DEFAULT, SET NULL
$update	string	The ON UPDATE option. Most DBMS support these options: RESTRICT, CASCADE, NO ACTION, SET DEFAULT, SET NULL
return	string	The SQL statement for adding a foreign key constraint to an existing table.

alterColumn() public method

Builds a SQL statement for changing the definition of a column.

public string alterColumn ( $table, $column, $type )
$table	string	The table whose column is to be changed. The table name will be properly quoted by the method.
$column	string	The name of the column to be changed. The name will be properly quoted by the method.
$type	string	The new column type. The getColumnType() method will be invoked to convert abstract column type (if any) into the physical one. Anything that is not recognized as abstract type will be kept in the generated SQL. For example, 'string' will be turned into 'varchar(255)', while 'string not null' will become 'varchar(255) not null'.
return	string	The SQL statement for changing the definition of a column.

batchInsert() public method

Generates a batch INSERT SQL statement.

For example,

$sql = $queryBuilder->batchInsert('user', ['name', 'age'], [
    ['Tom', 30],
    ['Jane', 20],
    ['Linda', 25],
]);

Note that the values in each row must match the corresponding column names.

public string batchInsert ( $table, $columns, $rows )
$table	string	The table that new rows will be inserted into.
$columns	array	The column names
$rows	array	The rows to be batch inserted into the table
return	string	The batch INSERT SQL statement

buildInCondition() public method

Creates an SQL expressions with the IN operator.

public string buildInCondition ( $operator, $operands, &$params )
$operator	string	The operator to use (e.g. `IN` or `NOT IN`)
$operands	array	The first operand is the column name. If it is an array a composite IN condition will be generated. The second operand is an array of values that column value should be among. If it is an empty array the generated expression will be a `false` value if operator is `IN` and empty if operator is `NOT IN`.
$params	array	The binding parameters to be populated
return	string	The generated SQL expression
throws	yii\db\Exception	if wrong number of operands have been given.

buildLikeCondition() public method

Creates an SQL expressions with the LIKE operator.

public string buildLikeCondition ( $operator, $operands, &$params )
$operator	string	The operator to use (e.g. `LIKE`, `NOT LIKE`, `OR LIKE` or `OR NOT LIKE`)
$operands	array	An array of two or three operands The first operand is the column name. The second operand is a single value or an array of values that column value should be compared with. If it is an empty array the generated expression will be a `false` value if operator is `LIKE` or `OR LIKE`, and empty if operator is `NOT LIKE` or `OR NOT LIKE`. An optional third operand can also be provided to specify how to escape special characters in the value(s). The operand should be an array of mappings from the special characters to their escaped counterparts. If this operand is not provided, a default escape mapping will be used. You may use `false` or an empty array to indicate the values are already escaped and no escape should be applied. Note that when using an escape mapping (or the third operand is not provided), the values will be automatically enclosed within a pair of percentage characters.
$params	array	The binding parameters to be populated
return	string	The generated SQL expression
throws	yii\base\InvalidParamException	if wrong number of operands have been given.

buildOrderByAndLimit() public method
