Querying problems con Many to Many relations: GROUP BY needed

[dlopeza]

I have a many to many relation. There is no "group by" in the DQL, so when I filer on a relationed entity, I dont have all the results. Maybe setting a "group by" field as a parameter or something would solve it.

A group by would still only return one result. I remember stumbling upon this before, I’m not sure what the best approach is here.

A concrete example of what you suggest would help, can you give me one please?
