Database Table Selector
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.
Dialog 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).
