Okay so someone went and explained way back when why ADO was an enhancement over DAO in the old vb5/6 days (Beacon from memory or it could have been someone else).

Not seeing a lot of advantages to PDO for MySQL queries over the traditional MySQL functions. Still have to hack out great wads of sql etc. Anyone actually found the killer reason to go to PDO?

We're doing so regardless, but not seeing it as the single bestest ever solution to multiple database type processing, you still need to be all over the various SQL implementations.
