The number of rows in a resultset is not known to the *server* until the
last one has been transmitted to the client.  It is impossible -- with
any version of any Sybase or Microsoft server -- to know the size of a
resultset in advance.  

For any insert/update/delete, the server returns "rows affected".
Obviously, the rowcount of a select statement can be captured by first
inserting the rows in a temporary table (INSERT INTO ... SELECT ...) .

I think if you dig a little deeper, you'll find someone, somewhere is
buffering the rows and providing a count.  If you can identify the
specific API and function call that works one way on IIS and another on
Apache, we can at least put it on the TODO.
