I have a query with several joins, where I am searching for specific data in certain columns. If I do this:
SELECT distinct on (s.description, st1.description, s.scene_id) s.description, s.scene_id, to_char(s.time_of_creation, 'MM/DD/YY HH24:MI:SS'), position_0_0_0_info, st.scene_thing_id, si.description, st.description, m.description from scenes s left outer join scene_thing_instances si on s.scene_id = si.scene_id left outer join scene_things st on si.scene_thing_id = st.scene_thing_id left outer join materials m on st.material_id = m.material_id left outer join scene_things st1 on st.ultimate_parent_id = st1.ultimate_parent_id where st.description ilike '%bread%' or st1.description ilike '%bread%' group by s.description, st1.description, s.scene_id, st.scene_thing_id, si.description, m.description order by s.description
No results are found, but if I just do this:
P { margin-bottom: 0.08in; }SELECT st.description, st1.description from scene_things st left outer join scene_things st1 on st.ultimate_parent_id = st1.ultimate_parent_id where st1.description ilike '%bread%' group by st.description, st1.description order by st.description
I get the results I expect (several hits).
What is the first query doing wrong?
I've tried adding st1.description to the SELECT list, and the GROUP BY clause, with no luck.
