Add support for FROM Class1 a1 JOIN Class2 a2 WITH cond queries

New Feature Major In Progress Unresolved All Alexander Benjamin Eberlei Wed, 25 Jan 2012 21:17:27 +0000 Sun, 30 Dec 2012 20:16:47 +0000 2.4 1 2 <p>Hi all!<br/> Maybe if this task is hard, you could do a simplier variant, "FROM Class1 a1 JOIN a1,a2 WITH a2 INSTANCE OF Class2"?<br/> Doctrine 2.3 supports it, but in fact, it does not work. I can't use Class2 fields in query, and Doctrine ignores the INSTANCE OF operator when building a native queries.<br/> I am working with system where I have many inherited classes with Class Table Inheritance. When I do a JOIN query, it generates native sql query more than 1KB(?!) length, and MySQL freezes for more than 7 minutes (?!) on it. It must join only tables for Class2, but it joins all my 20 tables inherited of my base class <img class="emoticon" src="http://www.doctrine-project.org/jira/images/icons/emoticons/sad.gif" height="20" width="20" align="absmiddle" alt="" border="0"/><br/> I don't know where to send bugreport <img class="emoticon" src="http://www.doctrine-project.org/jira/images/icons/emoticons/sad.gif" height="20" width="20" align="absmiddle" alt="" border="0"/><br/> It will be very good if I could manually select a joined class to make Doctrine do a better queries.<br/> Sorry for my english, I am from Moscow.</p>
