DB Writer

Inserts data rows into the database based on the selected columns from the input table. All selected column names need to exactly match the column names within the database table.
The output table contains two additional columns if the Append insert statuses checkbox is checked. The first extra column is the number of rows affected by the INSERT statement. A number greater than or equal to zero -- indicates that the command was processed successfully and is an insert 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.
