public function Connection::escapeLike in Drupal driver for SQL Server and SQL Azure 8.2

Same name and namespace in other branches

8 drivers/lib/Drupal/Driver/Database/sqlsrv/Connection.php \Drupal\Driver\Database\sqlsrv\Connection::escapeLike()

Escapes characters that work as wildcard characters in a LIKE pattern.

The wildcard characters "%" and "_" as well as backslash are prefixed with a backslash. Use this to do a search for a verbatim string without any wildcard behavior.

For example, the following does a case-insensitive query for all rows whose name starts with $prefix:

$result = $injected_connection
  ->query('SELECT * FROM person WHERE name LIKE :pattern', array(
  ':pattern' => $injected_connection
    ->escapeLike($prefix) . '%',
));

Backslash is defined as escape character for LIKE patterns in Drupal\Core\Database\Query\Condition::mapConditionOperator().

Parameters

string $string: The string to escape.

Return value

string The escaped string.
