I have to update ip adresses from a csv file to a MySQL table which column type is int unsigned.
How can I convert int unsigned to signed?

Thanks

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.
