Description
found this while reviewing justin's testsuite result bugs and it looks like we missed a verification in MCOL-171. It looks like datetime correctly supports where clauses on 0000-00-00 but not date values.
MariaDB [test]> create table t2(d date, dt datetime) engine=columnstore;
|
Query OK, 0 rows affected (0.54 sec)
|
|
|
MariaDB [test]> insert into t2 values ('0000-00-00','0000-00-00');
|
Query OK, 1 row affected (0.17 sec)
|
|
|
MariaDB [test]> select * from t2 where dt='0000-00-00';
|
+------------+---------------------+
|
| d | dt |
|
+------------+---------------------+
|
| 0000-00-00 | 0000-00-00 00:00:00 |
|
+------------+---------------------+
|
1 row in set (0.04 sec)
|
|
|
MariaDB [test]> select * from t2 where d='0000-00-00';
|
Empty set (0.01 sec)

the last query should also return a result. In justin's test suite, it means that the data setup code doesn't correctly set the d column to null causing some of the failures.
