> I'm using DbMerger to update the DataMap with attributes from the database. This solves a raft of problems, including how to let database managers modify length of fields from e.g. SQL Manager(which they are comfortable with).
> My DataMap states that the pk is generated by the database, but when that is not the case I'll get this exception:
> Caused by: java.sql.SQLException: Cannot insert the value NULL into column 'user_id', table 'qpb.dbo.users'; column does not allow nulls. INSERT fails.
