function db_query_range

db_query_range($query, $from, $count, array $args = array(), array $options = array())

Executes a query against the active database, restricted to a range.

Parameters

string $query: The prepared statement query to run. Although it will accept both named and unnamed placeholders, named placeholders are strongly preferred as they are more self-documenting.

$from: The first record from the result set to return.

$count: The number of records to return from the result set.

array $args: An array of values to substitute into the query. If the query uses named placeholders, this is an associative array in any order. If the query uses unnamed placeholders (?), this is an indexed array and the order must match the order of placeholders in the query string.

array $options: An array of options to control how the query operates.

Return value

\Drupal\Core\Database\StatementInterface A prepared statement object, already executed.

Deprecated

as of Drupal 8.0.x, will be removed in Drupal 9.0.0. Instead, get a database connection injected into your service from the container and call queryRange() on it. For example, $injected_database->queryRange($query, $from, $count, $args, $options);
