A new bcp option named --clienterr errorfile has been added to log any rejected row and its associated error message into an error file, if the row was rejected by the client due to errors detected by the client, such as conversion or format errors.
If you use the --clienterr option without the -e option, client error messages are written into the error file. However, server error messages are not written into the error file.
If you use the --clienterr option with the -e option, bcp does not proceed with the copy in or copy out operation.
