[RESOLVED] Invalid Operation Exception

Does anyone know why the following exception would occur:

"Dynamic SQL generation for the DeleteCommand is not supported against a SelectCommand that does not return any key column information."

All i am doing is deleting a row from my dataset and updating my database.

Please post the code generating this error.

Problem now solved it was because i didnt have a primary key on my table it was throwing this exeption for some reason. Cheers anyways always appreciate the help
