Thanks Markus,

See my reply to Helen. You have helped me over that SQL hurdle more so than anyone here with your generous detailed descriptions and explanations.

It is obvious to me now, that the former four tries I made at understanding and using SQL were doomed with the poor support I could find.

Thanks a heap, you really made a huge difference to my basic understanding of getting started with SQL. As I mention in the reply to Helen, SQLite3 seems to be my answer.

Dave
