if col == nil does following code will generate error message use unspecified type and '' column name?

In MySQL, I test this case, but it result is as follows:

mysql> create table if not exists show_warnings (a int);
Query OK, 0 rows affected (0.06 sec)

mysql> set @@sql_mode='';
Query OK, 0 rows affected (0.01 sec)

mysql> insert show_warnings values ('a');
Query OK, 1 row affected, 1 warning (0.01 sec)

mysql> show warnings;

| Warning | 1366 | Incorrect integer value: 'a' for column 'a' at row 1 |

Do we need to update this error code?

It is difficult for us to be completely consistent with MySQL in terms of error codes and error messages. What I want to do is to keep us self-consistent, the unique error code + reasonable error message. I think it can help users search the MySQL manual to find the problem if we use the code which MySQL also has (maybe not the same in the same scenes). If want to be completely consistent, I don't feel I can do it. :)
