Hi all,
I think I found a bug using the IN operator.
I have a table t populated as follow:
a | b
---+----
1 | 11
2 | 22
3 | 33
4 | NULL
(4 rows)
select * from t where b in (11,22,NULL);
a | b
---+----
1 | 11
2 | 22
(2 rows)
select * from t where b not in (11,22,NULL);
a | b
---+----
(0 rows)
-----------------------------------------------
I tried the same quesry in mysql and it give me
a different result. Who are right?
select * from t where b not in (11,22,NULL);
+---+---+
| a | b |
+---+---+
| 3 | 33|
+---+---+
1 row in set (0.00 sec)
