Adding a datetime datatype in front and use a value of ""1400-01-01 00:00:00""

Both c1 and cchar255 got saturated

MariaDB [mytest]> select * from t1;

+------+--------+--------+--------+--------+--------+--------+---------+----------+-----------+----------+

| c1   | CCHAR1 | CCHAR2 | CCHAR3 | CCHAR4 | CCHAR5 | CCHAR6 | CCHAR7  | CCHAR8   | CCHAR9    | CCHAR255 |

| NULL | z      | zz     | zzz    | zzzz   | zzzzz  | zzzzzz | zzzzzzz | zzzzzzzz | zzzzzzzzz | zzzzzzz  |

adding datetime to the end, then only c1 got saturated

+--------+--------+--------+--------+--------+--------+---------+----------+-----------+------------+------+

| CCHAR1 | CCHAR2 | CCHAR3 | CCHAR4 | CCHAR5 | CCHAR6 | CCHAR7  | CCHAR8   | CCHAR9    | CCHAR255   | c1   |
