Database Table Selector (legacy)

KNIME Base Nodes version 4.2.3.v202011031328 by KNIME AG, Zurich, Switzerland

This node is part of the legacy database framework. For more information on how to migrate to the new database framework see the migration section of the database documentation.

This node takes a database connection as input and allows selecting a table based on the incoming database JDBC connection. The node outputs the incoming connection together with the query which can later on be used in subsequent database manipulation nodes.

Options

SQL Statement
Enter SQL statement being executed here, for example SELECT * FROM mytable.
Additional SQL commands (create, drop, set parameter, etc.) can be added before the actual SELECT statement and are executed together line-by-line during configure and execute. Note, those additional SQL commands need to be separated by semicolon.
Database Browser
Click Fetch Metadata to connect to the database using the entered settings and to fetch all tables and display them grouped by type in the Database Browser.
Click on any table to retrieve all contained columns. Double-click on a table or column to insert its name into the SQL query at the current cursor position.
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).
