You can create a cursor on the server and move back and forth on it,
but that can be pretty complex and tie up the connection, expensive
both on client and server. I've used Progressive Fetch before, but
it's likely not what you want. However, try this:
A hack I ran into in a PHP framework (CodeIgniter) used this
workaround to emulate the "LIMIT" clause that other db have:
Take your SELECT <fieldlist> FROM <tables and joins> WHERE <clause>
ORDER BY <expression ASC/DESC>
Drop the 'top 20' and change to:
SELECT (row_number() OVER (order by expression), <fieldlist> FROM
<tables and joins> WHERE <clause> ORDER BY <expression ASC/DESC>) AS A
WHERE A.rownum BETWEEN (offset+1) AND (offset + limit)
Where offset is the starting row number (typically zero-based, hence
the plus one) and limit is the number of rows you want retrieved, 20
in your case.
This works with newer SQL Servers (I'm running it on 2008R2) but not
on older ones (I've heard it doesn't work on 2000, but you shouldn't
be using that anyway, right?)
