Implement SHOW WARNINGS;

[theodesp]

When invoking certain operations for example:

mysql> select log10(-1);
+-----------+
| log10(-1) |
+-----------+
|      NULL |
+-----------+
1 row in set, 1 warning (0.00 sec)

The result contains info about the number of warnings where you can later querry:

mysql> show warnings;
+---------+------+--------------------------------+
| Level   | Code | Message                        |
+---------+------+--------------------------------+
| Warning | 3020 | Invalid argument for logarithm |
+---------+------+--------------------------------+
1 row in set (0.00 sec)

It would be useful to provide that functionality
