Does the exception happen on any INSERT / UPDATE /
DELETE SQL command ?


If yes, then please do the following:
- create simple test application
- execute trivial INSERT / UPDATE / DELETE SQL command
- run application up to the exception
- when debugger will stop on the exception, copy the call stack
and past it into your reply
