          Description

          This query correctly returns a warning,
          because 'xxx' is not a valid number.

          mysql> select 'xxx'+1;
+---------+
| 'xxx'+1 |
+---------+
|       1 |
+---------+
1 row in set, 1 warning (0.00 sec)

mysql> show warnings;
+---------+------+-----------------------------------------+
| Level   | Code | Message                                 |
+---------+------+-----------------------------------------+
| Warning | 1292 | Truncated incorrect DOUBLE value: 'xxx' |
+---------+------+-----------------------------------------+
1 row in set (0.00 sec)

          This query does not produce a warning, which is wrong:

          mysql> select IF(1=1,'xxx','yyy')+1;
+-----------------------+
| IF(1=1,'xxx','yyy')+1 |
+-----------------------+
|                     1 |
+-----------------------+
1 row in set (0.00 sec)
