Hi,
I have a column 'id' within a table :
CREATE TABLE `reference` (
*`*id*`* smallint(5) unsigned NOT NULL auto_increment,
`study_name` text,
`author` text NOT NULL,
`date` date NOT NULL default '-00-00',
`reference` varchar(250) NOT NULL default '',
`title` varchar(250) NOT NULL
Many many thanks... I was in confusion. But how can I exten the table
size.
Regards
Naveen

You need to drop the constrains...

The string shown above converted into a number is 2005.
( Unless you think ist should be 1988 )
From the manual :
MIN() and MAX() may take a string argument; in such cases they return
the minimum or maximum string value.
so I understand that for a timestamp column, values are converted and
then compared as strings, then the function return a string, so adding
+ 0 convert it to a number
Thanks for the replies, works fine, I checked out the alter table syntax and

See my original post:

Primary key could've just as easily been another column. You have to
include another ADD command after the comma.
