Re: proc sql

First: please use some descriptive subjects than "proc sql". It would help to distinguish between your inquiries.
Second: what are you up to? Since you have severe more or less basic SQL questions I sugest that you take some formal training first, and then return to the forum more specific coding problems, or at least show the code you tried so far.
