RE: Joining to a join in SQL?

You can even have a mix of SQL views and DDS logical files within in one SQL view.

A really fun exercise is to do a "select * from yourview" in iNavigator SQL Scripts and use the visual explain tool. I have one SQL view that looks at several other SQL views that are joined and then unions to some other SQL views. This view is very slow, but I haven't found time for a better solution. The visual explain is barely readable when printed out on a 11"x17" piece of paper.

If they are SQL views then yes you can create a view over it

Even if the view involves additional joins?
