Re: How to force auto-increment field to increase monotonically

An auto-incrementing INTEGER allows values from 1 - 4294967295

How many skills were you thinking of inserting.

If the id has any meaning beyond the immediate scope of the database then don't use auto_increment. Despite its name, that's not what its for. Its purpose, as GD explained, is only to ensure uniqueness (of the PK). It could just as easily insert any unused random number between 1 and 4292967295 - but I imagine this would be harder for MySQL to manage.
