Thanks. Ryan. Wow, your tool is pretty amazing. I did not know it existed. The site is also very nice. Thank for the CTE links. I am a newbie to SQL, and I started with SQLite for a project for work in 2006 and now it has become bigger than I wanted/thought, which is pushing me to learn more and more about this fancy world of SQL. :-) Again, thanks for all the help. jos?
