we have following table:
CREATE TABLE `media_2_project` ( `media_2_project_id` BIGINT NOT NULL AUTO_INCREMENT, `project_id` BIGINT NOT NULL, `media_id` BIGINT NOT NULL, `media_file_id` BIGINT NOT NULL, # PRIMARY KEY (`media_2_project_id`), ... );
possible entries could be:
m2p_id | p_id | m_id | mf_id ----------------------------- 1 1 1 1 2 1 1 2 3 1 2 3 4 1 2 4 5 2 1 5 6 2 1 6 7 2 3 7
now we have a finder findAllByProjectId() and we want DISTINC data by media_id. so for project_id = 1 we should get 1 and 2.
normaly you could do this with this query:
SELECT DISTINCT o.media_id o.media_2_project_id FROM media_2_project o WHERE o.project_id = 13
but how can we do this with JBoss-QL?
