I need to add a section so that when a post is made there is a row (or column idk what their called) called locked that can hold the values 0 or 1 or true or false so i can tell if the post is locked. So i was wondering if somone could make me something i can query into my database to create this, thanks.

ALTER TABLE forumtutorial_posts ADD COLUMN locked TINYINT NOT NULL DEFAULT 0

thanks mate.
