Use Generators,

They are the easy to use, multi-thread, multi-connection and multi-
transaction safe. The concept is also now included in the SQL standard
as "SEQUENCES", Firebird 2 introduces the Get Next Value For [Sequence]

If you do decide to write your own, you would probably need to
implement a UDF to get the value, but make sure it is threadsafe!!!. If
you are currently implementing another DB, then check whether they
support the concept.
