Database connector Try/Catch

Hi Folks,
I’m trying to catch a error from the database connector (Hive). If the connection is not possible then load from a csv reader node. I cant seem to find a Try for the DB ports, just a catch. Is there any work around for this type of error that will try a DB port and if error is caught, load from a data port (csv reader). Image of flow below

Hi 501SCO,
the Catch nodes description states that it requires a try node before the failing node. As the Hive Connector does not have any input port, the only solution i see would be a “Try (Variable Ports)” before the Hive Connector.
Unfortunately we need an input for the Try node (we have to connect a output variable port to it). I tried it with a connection from the CSV Reader, this has the disadvantage that the reader has to be finished before the Database reading can start (see https://www.knime.com/nodeguide/control-structures/flow-variables/using-flow-variables-to-control-execution-order). Maybe a dummy node would be better here, if you are using a big CSV file.

However, this will catch an error in the Connector or DB reader node, and will use the CSV Reader instead.

Thanks this should work for now!
