This node is part of the deprecated database framework. For more information on how to migrate to the new database framework see the migration section of the database documentation .
This node creates a connection to an arbitrary JDBC database. You need to select an appropriate driver (if not available, add your vendor-specific driver under File > Preferences > KNIME > Database Driver) and the JDBC URL of the database (which is database specific). Login credentials can either be provided directly in the configuration or via credentials set on the workflow.
