> @LemonLiTree thank you for the quick reply, tried with 2.0.3-rc05 - exists+having works as intended. But exists behaviour still seems odd. Using the same tables: > > ```sql > select t1.id from t1 > where > exists(select 1 from t2 where t1.id = t2.t1_id and t2.id=5) and > exists(select 1 from t2 where t1.id = t2.t1_id and t2.id=6); > -- OK: returns 5 > > -- now try to invert the condition > select t1.id from t1 > where > not ( > exists(select 1 from t2 where t1.id = t2.t1_id and t2.id = 5) and > exists(select 1 from t2 where t1.id = t2.t1_id and t2.id = 6) > ); > -- BUG: no rows, expected 1,2,3,4,6 > > -- if I open parentheses using de Morgans' laws, it works: > select t1.id from t1 > where > not exists(select 1 from t2 where t1.id = t2.t1_id and t2.id = 5) or > not exists(select 1 from t2 where t1.id = t2.t1_id and t2.id = 6); > -- OK: 1,2,3,4,6 > ``` > > Should I create a separate issue for it?
