My query below returns however many rows fit the WHERE condition, in this case when they
year, period, week is <= 2009131. In my case it is returning 11 rows because I have
11 rows where the year,period, week is 2006XXX. However, this is not what I want. I
only need 4 rows returned to me and not all 11 no matter what the <= XXXXXXX part of
the where is.
I guess my question becomes is it possible to put a LIMIT of how many rows are returned on
a GROUP BY?
SELECT ROUND(AVG(page_hit)) as page_hit, ROUND(AVG(training_tracking)) as
training_tracking, ROUND(AVG(certificates)) as certificates, ROUND(AVG(team_members)) as
team_members, ROUND(AVG(evaluation)) as evaluation, CONCAT(year,period,week) as date
WHERE CONCAT(year,period,week) <= 2009131 AND region_id != 'AA'
GROUP BY date
ORDER BY date DESC LIMIT 0,77
