DB Update (Labs)

The output table contains two additional columns if Append update statuses checkbox is checked. The first extra columns is the number of rows affected by the UPDATE statement. A number greater than or equal to zero -- indicates that the command was processed successfully and is an update count giving the number of rows in the database that were affected by the command's execution A value of -2 -- indicates that the command was processed successfully but that the number of rows affected is unknown. The second shows a warning message, if any.
