Yes, PK field is calculated using GUID() function. I first added CalculateGUID function in the insert-sql (the difference in CalculateGUID is that API declaration is outside), but then took it out, because I'm not sure of using function in Select-SQL.

Also it looks like UpdateUserAndTime record rule is invoked too. It has if m.glDontUpdateUserAndTime check at the top, so it doesn't do anything even if it's called, but it's still time to call.
