Database Query Node: Incompatible port spec

KNIME Analytics Platform
#1

Dear all

I'm very new to Knime so it might be a simple question:

I try to use the Database Query node and as soon I connect it to a working Database Connector (or MySQL Connector)  I'll get an Error: Incompatible port spec, expected: DatabasePortObjectSpec, actual: DatabaseConnectionPortObjectSpec

Any help is highly appreciated, Markus

You need to select a table, e.g. with the DB Table Selector node before you can edit the query in the DB Query node. Note also the slightly different colors of the ports.
