Without this patch a query would like like: ``` SELECT c0_.Country AS sclr0 FROM Continent c0_ WITH (NOLOCK) WHERE c0_.Country = 38 GROUP BY sclr0 ``` Using the column alias in the GROUP BY clause. However this is not allowed on SQL Server. References: 1. http://stackoverflow.com/a/3841804 2. http://technet.microsoft.com/en-us/library/ms189499.aspx (Logical Processing Order of the SELECT statement) The correct query should be: ``` SELECT c0_.Country AS sclr0 FROM Continent c0_ WITH (NOLOCK) WHERE c0_.Country = 38 GROUP BY c0_.Country ```

Doctrine 2 is an object-relational mapper (ORM) for PHP 5.3.2+ that provides transparent persistence for PHP objects. It sits on top of a powerful database abstraction layer (DBAL). One of its key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), inspired by Hibernates HQL. This provides developers with a powerful alternative to SQL that maintains flexibility without requiring unnecessary code duplication.
