Inserts data rows into the database based on the selected columns from the input table.
If the database table does not exist it will be created by the node prior inserting the values. The new table will have a column for each input KNIME column. The database column name will be the same as the name of the input KNIME column. The database type is derived from the given KNIME type based on the output type mapping rules specified in the "Output Type Mapping" tab. All database columns will allow missing values (NULL). Please use the DB Table Creator node if you want to control the properties of the created database table.
If the table already exists in the database 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 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.
This tab allows you to define rules to map from KNIME types to database types.
