If I saw this sort of code I'd be appalled! It's possibly the worst way
to get the auto increment value. You won't notice it testing the site
out on your own, but all hell will break loose when you start getting a
lot of hits, and two people cause an auto increment at the same time!
ADOdb handles SEQUENCE correctly across all databases. Since MySQL does not
understand SEQUENCE or GENERATOR, ADOdb simulates it with a dummy table which
autoincrements and gets around the problem. Then one can use a secure generic
GetID ;)
