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

The SQL script is correct

ALTER TABLE your_table MODIFY some_column INT NOT NULL AUTO_INCREMENT;

but if you try so make before in the visual mode, with the mysql version 4.7.4, in the struct of the table

Appear when you create the table one option to say "A_I" , if you put your mouse appear message with AUTO_INCREMENT (The version of the foto is in Spanish version)
