Sorry but I was not clear. I need to insert a record only if it does not exist. If it does exists then I do nothing. However I do need to know if it was inserted. Its seems most efficient to just attempt the insert and look at the result. My only complaint is the log file is littered the error messages about attempting to insert a duplicate.
