The values of the selected columns are used in the command resulting in each row of the KNIME input table creating its own command that is send to the database with the corresponding values for execution.

SQL Statement

Enter the SQL Statement here, for example INSERT INTO table (col1) VALUES (1). Constant values and any identifier from the KNIME column and flow variable list can be used in the SQL statement by double clicking the column or variable name.
To open code completion press <CTRL> + <SPACE>. Table and columns names are only suggested if the metadata is available e.g. shown in the Database Metadata Browser. To perform undo press <CTRL> + Z and for re-do <CTRL> + Y.

Database Metadata Browser

The Database Metadata Browser allows you to browse the database metadata and to select a table or view. Click the Refresh button at the bottom right to re-fetch the metadata from the database. The data is grouped by database schema and type e.g. view or table. By clicking on an entity it shows contained elements. If you click on a table or view the dialog will fetch the column names and types of the selected element. To select a table or view select the name and click OK or double click the element. To search for a particular table or view enter the name or parts of the name into the search field and click on the Magnifying Glass button or press enter.

Column List

The list contains the columns that are available in the KNIME input table. Double clicking any of the entries will insert the respective identifier at the current cursor position (replacing the selection, if any).

Flow Variable List

The list contains the flow variables that are currently available at the node input. Double clicking any of the entries will insert the respective identifier at the current cursor position (replacing the selection, if any).

Batch size

Enter a number greater than 0 for the number of rows used in one batch job. Entering 1 disables batch processing. This way only one row is processed at a time.

Fail on error

Disable this if you want to continue after a database error.

Append manipulation status columns

Enable this to append two additional (status and error) columns to the output table (see description).
