Hi everybody !
A have a discontinued AUTO_INCREMENT sequence when i insert data in a
table with a 100 (or more) items SELECT request.
The problem (or situation) is reproductible, you can see an example below.
Anybody could explain this to me ?
Cheers

My MySQL version : Ver 14.14 Distrib 5.1.41, for debian-linux-gnu (i486)
using readline 6.1
== Example =================================
-- CREATE test table
mysql> create table test(`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`name` VARCHAR(255), `test` int(10), KEY `keyid`(`id`)) ENGINE=InnoDB
DEFAULT CHARSET=latin1;
Query OK, 0 rows affected (0.00 sec)
-- INSERT DATA FROM ANOTHER TABLE
mysql> insert into test(name) select `name`from user limit 100;
Query OK, 100 rows affected (0.01 sec)
Records: 100 Duplicates: 0 Warnings: 0
-- AUTO_INCREMENT ID CHECK => OK
mysql> select max(`id`) from test;
+-----------+
| max(`id`) |
+-----------+
| 100 |
+-----------+
1 row in set (0.00 sec)
--INSERT DATA WITH CHECKED SELECTREQUEST 2 => DATA INSERT OK
mysql> insert into test(name) select `name` from userlimit 100;
Query OK, 100 rows affected (0.01 sec)
Records: 100 Duplicates: 0 Warnings: 0
-- AUTO_INCREMENT ID CHECK => should be 100 + 100 = 200
-- => 27 IDs are unset, first ID of 2nd insert is 128 instead of 101
-- No field between 100 and 128
mysql> select max(`id`) from test;
+-----------+
| max(`id`) |
+-----------+
| 227 |
+-----------+
1 row in set (0.00 sec)
== End Example =================================
