i know this is really late..but hopefully it will help someone else in the same predicament.
took me an hour to find this out..
TOP n (where n is the number of rows)
TOP n PERCENT (where n is the percent of results that get returned)
example:
SELECT TOP 1 *
FROM mw_agenda
ORDER BY ag_artist
note the wonky syntax. TOP must preceed the rest of your select statement. don't know why..
