   INSERT INTO forum_posts (topic_id, user_id, subject, content) VALUES (@tid, i_user_id, i_title, i_content);

END;

I’m not sure what’s wrong with it. MySQL tells me all sorts of things are incorrect, it just doesn’t want to be created. Also, the parameters are identical types and lengths to their respective tables.

Answer 1

It is your first “;” that breaks procedure definition and mysql thinks you are done and treats whatever goes after “;” as another query.
You have to use delimiter for stored procedures.
