Debugging OleDbAdapter.Update

Does anyone have any suggestions for efficient ways to debug database problems? For example, my working code recently quit working on the following statement: OleDbDataAdapter1.Update(DataSet1) The error is: A first chance exception of type 'System.FormatException' occurred in mscorlib.dll Additional information: String was not recognized as a valid Boolean. It looks like there's a field mismatch between the dataset & the underlying database which I am trying to update. All I need to do is to figure out which fields are mismatched. My usual approach of breaking out into the debugger is not helpful, because the dataset structure is endlessly nested & takes forever to interpret. Any suggestions are welcome.
