Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Open an SQL editor connected to your MySQL database and execute the following statement:

ALTER TABLE `my_database`.`my_table` 
CHANGE COLUMN `TheColumnName` `TheColumnName` INT(11) NOT NULL ;

Open in new window

This way it eliminates the UNSIGNED flag from your column definition.
You can specify another size for your INT, not necessarily 11.
