Oh.  Sybase?  OK, I was just trying something I thought was simple.  How
about "select 1 as A union select NULL order by A desc"?  That should
(not) work.

Unfortunately, it's not implemented, as Brian points out.  But it's a good
idea to know where the online docs are, so here goes:

http://manuals.sybase.com:80/onlinebooks/group-cn/cng1250e/dblib/@ebt-link;nh=1;pt=1727?target=%25N%15_36280_START_RESTART_N%25;;__next_hit__=7748;DwebQuery=dbsetnull

Easier to remember, go to:

        http://sybooks.sybase.com/middleware.html

Choose "Open Client/Server", followed by "Open Client DB-Library/C
Reference Manual" and search for dbsetnull.
