It turns out that INNER JOIN is in the ANSI 92 standard.
However virtually the only place that I have seen it used is Access. And certainly I have never seen anyone working on a non-Microsoft database who uses the INNER JOIN syntax. We all do as, say, Spiceware did above and put the joins in the WHERE clause.
Sorry for my misimpression, but the general observation holds. Microsoft uses the INNER JOIN syntax, but you don't see many non-Microsoft people using it.
