Execute database query to populate a Value Selection Configuration inside a component

Hi all,

I am trying to populate a value selection configuration node with the result from a database query. The query is done inside the component. The component is receiving a DB Data Connection as input, and the DB Connection for the query is extracted using a DB Connection Extractor node.

However, when in a workflow I connect the component to a DB Data Connection output port (already executed), I get a warning indicating that the input table does not contain any column with domain information and the value selection is empty in the configuration; I have to execute the component to get it populated.

Is there any way to solve this?

Many thanks in advanced

Hi Fando,

Welcome to KNIME Forum!

Is the DB Connection Extractor node inside the component? Can you please share a sample workflow or screenshot of your workflow so i can better understand the problem.

Best regards,
Hannan
