tpimental Posted May 30, 2007 Share Posted May 30, 2007 I've been struggling with this query for way too long and decided I needed some help. Seems simple enough, but I get 0 results. I'm trying to get the latest date of a set of IDs (loc_id) in a report set only when that date is older than 1 year. (mysql version 4.0.27) SELECT Max( report_date ) AS LatestDate, loc_id FROM report_index WHERE 'LatestDate' < curdate( ) - INTERVAL 365 DAY GROUP BY loc_id LIMIT 0 , 500 Table looks something like this: loc_id report_date 1 12/13/2001 2 3/4/2003 2 12/13/2001 3 6/4/2003 3 6/4/2003 4 3/6/2003 4 3/6/2003 5 3/14/2003 5 3/14/2003 5 9/8/2003 5 9/8/2003 Link to comment https://forums.phpfreaks.com/topic/53490-solved-help-with-max-dates/ Share on other sites More sharing options...
