A CountSqlWalker and LimitSubquerySqlWalker have been implemented. By
default the Paginator will use these SQL walkers. When a query already
uses custom SQL walkers, the Paginator will fall back to the existing
TreeWalker implementations. Improvements:
* Support for more complex DQL queries using named mixed results with
GROUP BY and HAVING. For example:
SELECT g, u, COUNT(u.id) AS userCount
FROM Entity\Group g LEFT JOIN g.users u
GROUP BY g.id
HAVING userCount > 0
* Support for entities with composite primary keys in the CountSqlWalker
and LimitSubquerySqlWalker. Only the WhereInWalker still needs to be
updated for full composite primary key support. But someone smarter
than me needs to look at that and figure out how to build a WHERE IN
query that can select rows based on multiple columns.
Doctrine 2 ORM
Master: 
2.2: 
2.1: 
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.
