Ah so.  Well, friendliness aside, I'd go with the spec's syntax.

It looks to me like SQL99 allows

        GET DIAGNOSTICS :a = ROW_COUNT, :b = OID, ...;

which is at least as good as the SELECT syntax, if not better since each
target variable and info spec are kept together.

He's still engaged in moving from Germany to Norfolk, VA.  I think his
net-access is somewhat erratic :-(
