How to add auto-increment to column in mysql database using phpmyadmin?

Question

I\'ve been trying to add auto-increment to one of my columns (basically an ID) but I can\'t find the auto-increment option for my column. Any idea where it is?

Answer 1

This wont work if there are any foreign keys defined, and that is very likely for id fields.

use:

ALTER TABLE tablew_name CHANGE id id BIGINT(20) NOT NULL AUTO_INCREMENT;

instead
