MariaDB [test]> update t t1 join t t2 set t1.a = t1.a + 100 order by t1.a; |
ERROR 1264 (22003): Out of range value for column 'a' at row 1 |
ROW_NUMBER from MDEV-10075 returns the same value.
It is set to 1 even when the update cannot be performed due to safe mode. In this case it is not reported in the error message, but ROW_NUMBER demonstrates it:
