Hey @HaveF ! So basically there are databases that create tables other than the standard “TABLE” or “VIEW” type. This is referenced e.g. in this thread : Reading HANA Tables
DuckDB for some reason creates each table as a “BASE TABLE” type (VIEW works out of the box though) . So this has to be added to the following setting of the DB connector node " List of table types to show in metadata browser. When you’re using a new database and you’re not sure why you’re not seeing the tables, the following Vernalis node is useful , so you know how to modify the setting https://nodepit.com/node/com.vernalis.knime.db.nodes.rsettobdt.DBListTableTypesNodeFactory
