Another problem: the second and third results from each of query 2 and query 3 are identical; this should not be so because the first column is a primary key. Note that kfznr is allegedly TEXT ... interesting question: is it possible to have two rows, one where typeof(kfznr) is text and the other is integer AND they are not considered equal for primary key purposes?
