Errors when autoincrement value is used for PK

[guriandoro]

mysql [localhost] {msandbox} (sakila) > show create table actor\G
*************************** 1. row ***************************
       Table: actor
Create Table: CREATE TABLE `actor` (
  `actor_id` smallint(5) unsigned NOT NULL AUTO_INCREMENT,
  `first_name` varchar(45) NOT NULL,
  `last_name` varchar(45) NOT NULL,
  `last_update` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`actor_id`),
  KEY `idx_actor_last_name` (`last_name`)
) ENGINE=InnoDB AUTO_INCREMENT=65535 DEFAULT CHARSET=utf8
1 row in set (0.00 sec)

SELECT COUNT(*) FROM actor;
+----------+
| COUNT(*) |
+----------+
|        0 |
+----------+
1 row in set (0.00 sec)

As we can see, the PK is a smallint, the table is empty, and the AUTO_INCREMENT value is at 65535 (this was a table that was full, then all rows were deleted).

If we try to use the tool, it will insert only one row, and will error out with duplicate key errors:

Only one row is inserted:

It may make sense to try to choose another PK value on error.
