Sql dialect trait
Returns an associative array of methods that will transform Expression objects to conform with the specific SQL dialect. Keys are class names and values a method in this class.
WHERE clause of a query. Returns the passed query after rewriting the DISTINCT clause, so that drivers that do not support the "ON" part can provide the actual way it should be done
Returns a callable function that will be used to transform a passed Query object. This function, in turn, will return an instance of a Query object that has been transformed to accommodate any specificities of the SQL dialect in use.
Quotes a database identifier (a column name, table name, etc..) to be used safely in queries without the risk of using reserved words
_deleteQueryTranslator( Cake\Database\Query $query )
Apply translation steps to delete queries.
Chops out aliases on delete query conditions as most database dialects do not support aliases in delete queries. This also removes aliases in table names as they frequently don't work either.
We are intentionally not supporting deletes with joins as they have even poorer support.
Cake\Database\Query $query Cake\Database\Query_expressionTranslators( )
Returns an associative array of methods that will transform Expression objects to conform with the specific SQL dialect. Keys are class names and values a method in this class.
_insertQueryTranslator( Cake\Database\Query $query )
Apply translation steps to insert queries.
Cake\Database\Query $query Cake\Database\Query_removeAliasesFromConditions( Cake\Database\Query $query )
Removes aliases from the WHERE clause of a query.
Cake\Database\Query $query Cake\Database\QueryIn case the processed query contains any joins, as removing aliases from the conditions can break references to the joined tables.
_selectQueryTranslator( Cake\Database\Query $query )
Apply translation steps to select queries.
Cake\Database\Query $query Cake\Database\Query_transformDistinct( Cake\Database\Query $query )
Returns the passed query after rewriting the DISTINCT clause, so that drivers that do not support the "ON" part can provide the actual way it should be done
Cake\Database\Query $query Cake\Database\Query_updateQueryTranslator( Cake\Database\Query $query )
Apply translation steps to update queries.
Chops out aliases on update query conditions as not all database dialects do support aliases in update queries.
Just like for delete queries, joins are currently not supported for update queries.
Cake\Database\Query $query Cake\Database\QueryqueryTranslator( string $type )
Returns a callable function that will be used to transform a passed Query object. This function, in turn, will return an instance of a Query object that has been transformed to accommodate any specificities of the SQL dialect in use.
$type the type of query to be transformed (select, insert, update, delete)
quoteIdentifier( string $identifier )
Quotes a database identifier (a column name, table name, etc..) to be used safely in queries without the risk of using reserved words
$identifier releaseSavePointSQL( string $name )
Returns a SQL snippet for releasing a previously created save point
$name rollbackSavePointSQL( string $name )
Returns a SQL snippet for rollbacking a previously created save point
$name savePointSQL( string $name )
Returns a SQL snippet for creating a new transaction savepoint
$name
