Question

I have a file upload site, and I want to run a maintenance script that will run every day and delete items that haven’t been accessed in a week. I log views for each day, and each item into a table:

• hit_itemid
• hit_date
• hit_views

The main table actually has the files that were uploaded, for the purposes of this example, its just vid_id, vid_title thats in this table, and vid_id will equal to hit_itemid.

I have a query as follows:

 SELECT vid_id, 
        vid_title, 
        SUM(case when hit_date >= '2009-09-17' then hit_hits else 0 end) as total_hits 
   FROM videos
  LEFT JOIN daily_hits ON vid_id = hit_itemid 
  WHERE vid_posttime <= '$last_week_timestamp' AND vid_status != 3
  GROUP BY hit_itemid 
  HAVING  total_hits < 1

But this always returns a single record.

How can I rewrite this query?

Answer 1

first guess, may be you have to do a

GROUP BY vid_id

instead of

GROUP BY hit_itemid
