I think MySQL has auto-increment columns instead. As for the rest of the
differences, I couldn't supply a full list but from what I know:

- transactions are only supported on InnoDB tables
- foreign keys only supported on InnoDB tables
- no sub-queries
- no stored procedures
- no triggers or constraints
- crap/non-existent range checking
- no views
- don't expect adherence to SQL standards

No doubt others will be able to correct/expand this list. I haven't used
MySQL for about 4 years and always _detested_ it. Happily, on migrating to
Linux, I discovered PostgreSQL and I've not touched MySQl since :)
