I'll defer to the SQL standard gurus on this, as well as to the internals guys, but I suspect there is a difference between the standard itself and implementor details, such as how char, varchar, varchar2 and text are implemented. As long as things work as specified, I don't think the standard cares much about what's happening behind the curtain. -- Mike Nolan
