Hi all,

Rich is correct on the first point here. The "?var" essentially works like macro substitution. Note that if var has a valid date value, "var" and "?var" will work exactly the same way when the SQL statement gets processed.

I suspect Rich is also correct on the second point. Pierre will have to elaborate on this one. Thanks Marc for pointing out the "select *.." and column creation rule thing to me. I was sure I had read somewhere that that was not allowed, but I am most likely confused...happens all the time!
