DB Row Inserter

Inserts data rows into the selected database table based on the values from the selected KNIME input table columns. All selected column names need to exactly match the column names within the database table. The column order of the KNIME table and the database table do not need to match.

Options

Database name

The name of the database (or catalogue) to use.

Schema name

The optional database schema name.

Table name

Name of the database table to insert into.

If a database error occurs

The option allows you to change the behavior if a database error occurs.

• Fail: The node will abort the execution and fail on errors.
• Ignore: The node will ignore errors.

Batch size

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

Columns to write (SET in SQL)

Select the columns which should be merged in the database e.g. if a matching row exists the values of the selected columns are updated otherwise a new row is created and the values of the selected columns are inserted in to the corresponding database columns. The column names in the KNIME input table need to match the column names in corresponding database table. In SQL this is equivalent to the SET columns.

Append status column (to KNIME table)

If selected, it adds an extra column to the output table. The status column is the number of rows affected by the SQL 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.

Status column name

Name of the new status column.

Append error column (to KNIME table)

If selected, it adds an extra column to the output table. The error column shows a warning message, if any.

Error column name

The name of the error column.

Disable DB Data output port

Select this option to disable the DB Data output port and the execution of the metadata query at the end of the node execution which might cause problems with databases that do not support subqueries.

• Column selection type: The option allows you to select how the column is matched.
  • Manual: Use the exact name of the column
  • Regex: Allow regex expressions to select multiple columns
• Column name: The name or regex expression.
• Source type: Datatype to map from.
