   In MySQL, it will also return 0 but with a warnings.
   Doris currently don't have warning system, so I think we should simply make it same as mysql?
   
   ```
   mysql> select cast("e465s" as decimal);
   +--------------------------+
   | cast("e465s" as decimal) |
   +--------------------------+
   |                        0 |
   +--------------------------+
   1 row in set, 1 warning (0.06 sec)
   
   mysql> show warnings;
   +---------+------+--------------------------------------------+
   | Level   | Code | Message                                    |
   +---------+------+--------------------------------------------+
   | Warning | 1292 | Truncated incorrect DECIMAL value: 'e465s' |
   +---------+------+--------------------------------------------+
   1 row in set (0.06 sec)
   ```
