Sql filtering id's -
i want create sql query lets me make top 5 of used ids in table. table has these columns:
reservationid costumerid roomid hotelid
i'm trying top 5 of used hotel ids.
i thought had use count function doesn't seem work. counts hotelids , doesn't see difference between id's
select count(hotelid) reservation;
can me push me in right direction?
thanks in advance!
select count(`hotelid`) `freq`, `hotelid` `reservation` group `hotelid` order `freq` desc limit 5 ;
