The current code I have finds the average and shows all 4. I am trying to trim it down to holy show the information for the top 2 highest average,
SELECT BRANCHSUBURB, AVG(SESSIONPRICE)
FROM BRANCH NATURAL JOIN SESSIONS
GROUP BY BRANCHSUBURB
ORDER BY BRANCHSUBURB;
ie should only show manly and cronulla click image click me
Just use order by
and limit
:
SELECT BRANCHSUBURB, AVG(SESSIONPRICE)
FROM BRANCH NATURAL JOIN SESSIONS
GROUP BY BRANCHSUBURB
ORDER BY AVG(SESSIONPRICE) DESC
LIMIT 2;
Note: I strongly advise you not to use NATURAL JOIN
. In my opinion, it is a bug waiting to happen. The NATURAL JOIN
works based on any columns that have the same names in the two tables -- it doesn't even use declared foreign key relationships. It is much better to use a regular join with a USING
clause.
