Selecting Tables without SQL-Statements

Is there a way to select import-tables vom databases inside Knime instead of selecting them with a SQL-Statement? I would like to add Tables to Knime without first opening the database and looking for the tablename. Instead, a node with a dropdone-selection would be nice. Is there something like this? Or can i build db-reader nodes outside with java (build the sql-string with java)?

thx
