Hello. Maybe someone have experience with this kind of problem: I’ve downloaded drivers from http://dev.monetdb.org/downloads/Java/Jul2015-SP4/ http://dev.monetdb.org/downloads/Java/Jul2015-SP4/ added them to KNIME and now, when i’m trying to make something more difficult than just counting rows in table, I see an error: ERROR Database Reader 0:3 SQL Exception reading Object of type "2005": Operation getCharacterStream() currently not supported - all further errors are suppressed and reported on debug level only ERROR Database Reader 0:3 Execute failed: Cell at index 1 is null!
