How to define a DATE column as primary key in a time-series data?

KNIME Analytics Platform
13

@mlauber71 I am trying to stick with a simple solution that works by default. The same workflow has been suggested for @takbb and seemed to have worked -DB Table Creator creates table without data - #5 by takbb

@takbb if we use DB SQL Executor node, do we even need DB Table Creator node at all? Anyway, that SQL snippet ended up in error :frowning:

Overall, I think this should be a rather simple update option in KNIME to set the Primary key.
