Database Looping no longer working

Hi @zhuma, Could this be similar to the issue outlined here on a different jdbc driver?

Basically it tries to call isValid which isn’t supported by the driver, so you need to supply a validation query in the config instead. Might not be, but looks very similar to me.

I came across this same issue recently when assisting with SQL Server too… buried in here… KNIME to SQL Server - #10 by takbb

I don’t recall if it has to return zero, or just a value but obviously the query has to be syntactically correct for your database.
