DB SQL Executor

KNIME database nodes version 4.3.2.v202103021015 by KNIME AG, Zurich, Switzerland

This node allows custom SQL statements to be executed on the input database. The output port can be used for flow control, to prevent subsequent nodes from executing if one of the statements fails.


SQL Statement
Enter new database statement(s). This node supports multiple statements with a custom delimiter (see SQL Statement separator).
To open code completion press <CTRL> + <SPACE>. Table and columns names are only suggested if the metadata is available e.g. shown in the Database Metadata Browser. To perform undo press <CTRL> + Z and for re-do <CTRL> + Y.
Database Metadata Browser
The Database Metadata Browser allows you to browse the database metadata and to select a table or view. Click the Refresh button to re-fetch the metadata from the database. The data is grouped by type. By clicking on an entity it shows contained elements. To select a table or view select the name and click OK or double click the element. To search for a particular table or view name enter the name or parts of the name into the search field and click the search button.
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).
Support multiple SQL statements
Enable this option if the node should support multiple statements.
SQL Statement separator
This is the separator that separates statements if the support multiple SQL statements option is enabled. The delimiter itself is removed from the statement.

Input Ports

Database connection to connect to database.
