title: Auto increment stopped in MySQL?
body: <p>I'm working on a script that sadly I inherited - with no commenting or anything. Argh! 
  For testing purposes I duplicated one of the tables in the database which had an auto-incrementing ID. When the data is saved to the database, though, the ID number just reads "0" -- which is the default for that column. I'm not sure why it's not auto increasing anymore... any thoughts? Thank you!</p>
