To what do you disagree, the bit about rows, or the bit about columns, or
both? The return of rows is limited, I believe, by any S/O specs. The
columns available are only those that are in the logical, right?

I've not looked at Interactive SQL in a while. Do all the fields of the
physical appear when you prompt the SELECT clause, or only those of the
logical you've named?
