How about: SELECT convert( varchar,eventime,110) as date from events, badge, count(convert( varchar,eventime, 110)) as count WHERE events.cardnum = badge.id and devid = '1' and convert( varchar, events.eventime, 110) BETWEEN '$startdate' and 'enddate' AND type = '1' GROUP BY convert( varchar,events.eventime, 110), badge > I'm using some proprietary software/hardware where when a visitor swipes > their entry card, it is recorded in a mssql 2000 server.
