Hey folks. I'm getting some weird behaviour out of Auto_increment.
If I enter a attempt to INSERT a row into a table with a UNIQUE index,
where the insert would violate uniqueness of existing data, I'm seeing
the auto_increment increase even though the insert fails.
The server in question is
It will also update the auto_increment column when you ROLLBACK a failed
insert:
mysql USE test;
Database changed
mysql SELECT * FROM t1\G
Empty set (0.00 sec)
mysql DROP TABLE t1;
Query OK, 0 rows affected (0.06 sec)
mysql
mysql CREATE TABLE t1(
- id INT UNSIGNED NOT NULL AUTO_INCREMENT,
Hmm, that makes sense. I should have thought of that. Thanks!
