Hi Karen, Yes it does look as though I am using them backwards. I am at a bit of a loss as to how to get around this problem, though it is Monday morning and my brain isn't fully into gear yet. Can anyone think of a way for me to bypass the transaction management? I believe that even if I execute an insert statement via the database cursor the transaction management will still take place, is this correct?
