MYSQL auto_increment not incrementing/something's wrong..

[Dragen]

Hi,

I'm having a strange problem when I try to add something to a table in my database.

MYSQL server: 5.1.32 & 5.0.77 (I've tried both)

 

I have a table called store_items, which as an id Primary Key, which auto increments.

I have been using it and adding/removing rows from it with no problem, but it now seems that the auto_increment value is 'stuck'.

I've just added a 127th row and when I try and add another it throws up this error:

 SQL Query:

INSERT INTO `daisymoon`.`store_items` (
`id` ,
`name` ,
`price` ,
`qty` ,
`cat_id` ,
`keywords` ,
`description` ,
`weight` ,
`i_date` ,
`live`
)
VALUES (
NULL , 'test', '1.00', '1', '1', '', '', '', '2010-03-16 13:54:20', '1'
)


MySQL Said:

#1062 - Duplicate entry '127' for key 'PRIMARY' 

 

But as you can see, I'm not entering an id :/

I've also tried setting the id to 128 in the SQL statement, which still brought up the same error.

I then tried changing the auto_increment value on the 'Operations' page in MyAdmin.. same problem.

 

Does anyone have any advice?

Surely there's no limit to the auto_increment value?? I can't think what would cause this to happen.

 

Kind regards.

Doesn't that suggest to you that the column definition being used can only hold that many values, such as if it were a TINYINT?

Thank you so much!

I feel rather silly now, as I'd never actually looked into how large a number a tinyint could hold and it didn't even cross my mind..

 

I've changed it to an int now and it works fine.

 

Thanks again!
