DB Delete (Table)

Deletes all data rows from the selected database table that match the values of a row from the selected KNIME input table columns. All selected column names of the KNIME table need to exactly match the column names inside the database. Only the rows matching all values of the selected column of any given input row will be deleted. The column order of the KNIME table and the database table do not need to match.
The output table contains two additional columns if Append delete statuses checkbox is checked. The first extra columns is the number of rows affected by the DELETE 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.
