Yeah I basically had that with my previous SQL statement, I was grouping by event.cardnum instead of counting the cardnums by date. I think what I'm trying to do is beyond the scope of SQL and I'll have to write some PHP to take the SQL statement results and feed them into an array and count the distinct cardnums for each date and then spit it all into an html table. thanks On Wed, 21 Apr 2004, Daniel Clark wrote: > AND: any count >=1 shows they came in that day. > > 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.
