Question

I’d like to be able to get the identity value back after calling an insert statement. I can do this now and it works fine with SQL server by adding SET @RETURN_VALUE = SCOPE_IDENTITY() and using an out parameter.

The problem is that this would only work with SQL server and I need to support Oracle and SQLite as well. Now I know could write separate code for each but is there a generic way to do this in .NET?

Java for example has a getGeneratedKeys method which can be called after the insert, returning a result set of generated column names and values.

Any similar construct in .NET?

TIA

Unfortunately each DBMS has its own specific way of retrieving the last inserted identity value, so you have to write specific code for each DBMS.
