Bltoolkit - Dealing with identity with multiple db's

How do I deal with identity when I'm supporting multiple db's with Bltoolkit. I know that BL supports InsertWithIdentity call with linq 开发者_Go百科whne doing inserts, but I think it only works with Sql Server and in this instance I don't want to use it in this instance

Is their a better way doing. Pehaps creating some kind of identity map to store the last primary key value for a particular entity stored.

Any advice would be helpful. Thanks scope_creep

MySql supports AUTO_INCREMENT, so it's not a problem.

For Oracle there are two ways to implement identity:

1. Define a trigger.
2. Use a sequence.
