Hi, I am trying to deal with empty values so that I can graph data over a 24 hour period without gaps.
I created a table called HOURS which simply has 0->23 and I am trying to do a join on this to produce the desired results. I think that the DATE_FORMAT in the query is screwing things up. The query looks something like this: SELECT COUNT(*),DATE_FORMAT(timestamp,'%H') AS hour FROM HOURS LEFT JOIN event ON HOURS.hour=hour WHERE timestamp BETWEEN '2007-01-09 04:00:00' AND '2007-01-10 04:00:00' AND sid=2 GROUP BY HOURS.hour; Any help would be appreciated.
