Database Looping (deprecated)

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 runs SQL queries in the connected database restricted by the possible values given by the input table. It establishes and opens a database access connection from which to read data and restricts each SQL query so that only rows that match the possible values from the input table are retrieved.

The place holder in brackets for table name and table column must be replaced, while the possible value place holder enclosed in hashes must not be edit and will be resolved during execution.

If the optional input is connected the database connection information is taken from the port, otherwise you need to specify the connection information in the dialog.

Make sure you have your vendor-specific database driver registered in the KNIME preference page (section Database Driver).
