Good to know and looks like it might fix my problem. Except that MySQL doesn't support WO's syntax for outer joins. Looks like it's another point for switching to postgreSQL, maybe later though. Switching over now would be a bit of a headache.

I also still think it should be classified as a bug. It would have worked if WO hadn't optimized the SQL incorrectly, I was able to take the two independent SELECT statements and just put an OR between them and got the expected results. Guess I'll build a small sample project and head on over to the bug reporter.


My guess is you have not defined relationship properties correctly.  

This is the most common cause of odd query results.


E.g. an optional to-many relationship should be defined as left join.  

If you fail to do so an inner join will eliminate rows where the  

right side of the join is null

Having a little trouble with this one, its only what I can assume  

is a bug.


I have two EOQualifiers, say A and B.


If I search the database with A I get objects a and b.

If I search the database with B I get the object c.


If I search with an EOOrQualifier generated from A and B I get only  

object c. Naturally I'm expecting a, b, and c.


Is there anything that could cause an EOOrQualifier to behave like  

this or is it a bug? Object's a, b, and c are all from the same  

table. The qualifiers A and B do have a contains selector for a  

many to many. This is with mysql v. 5.0.37.
