@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?
