MySQl - SQL - Top 5 records per day - mysql

Question

With respect to the data set below, I'm trying to get the top 5 records per day on a MySQL database. It's a table of web page visits & my aim is to find out the 5 most visited pages.
I'm comfortable getting just the top 10 in a given date range, but, have not been able to manage to get a query going for the topic in question.
I did try the below
select
VISIT_DATE,
group_concat(PAGE_ID order by NUM_VISITS desc separator ',') as pagehits
from
PAGEVISITS
where
VISIT_DATE >= '2015-07-01' and VISIT_DATE <= '2015-07-15'
group by
VISIT_DATE
but I can't get SUM(NUM_VISITS) int here & I couldn't get group byVISIT_DATE` which makes it pretty useless. This apart, this is how far I've got
select
VISIT_DATE,
PAGE_ID,
SUM(NUM_VISITS) as pagehits
from
PAGEVISITS
where
VISIT_DATE >= '2015-01-01' and VISIT_DATE <= '2015-03-15'
group by
VISIT_DATE,
PAGE_ID
order by
pagehits desc
limit 5;
which obviously is not top 5 per day. Also, there could be more than one page that can end up having the same number of page hits obviously & may also end up appearing as one of the top 5 which is why I tried using group concat to display all those PAGE IDs whose number of page hits is in the top 5 page hit count for that day.
I'm not a seasoned SQL coder. Could I please request assistance to get this working. If I've not sounded clear anywhere, please do let me know.

Answer 1

If this is going to be used daily, then you should consider to create a separate table and fill the data in it using procedure. There is still better way to do this(using merge). This is just for your reference.
create table daily_results
(`VISIT_DATE` date, `PAGE_ID` varchar(20), `SERVER_NAME` varchar(50), `NUM_VISITS` int);
CREATE PROCEDURE proc_loop_test( IN startdate date, in enddate date)
BEGIN
WHILE(startdate < enddate) DO
insert into daily_results (select * from PAGEVISITS where VISIT_DATE=startdate order by NUM_VISITS desc limit 5);
SET startdate = date_add(startdate, INTERVAL 1 DAY);
end WHILE;
END;
call it using
call proc_loop_test(`2015-01-01`,`2015-03-15`);
select * from daily_results;

Answer 2

The query should be
select sub.*,
CASE WHEN #vd!=VISIT_DATE THEN #rn:=0 ELSE #rn:=#rn+1 END as row_num,
#vd:=VISIT_DATE
from (
select
VISIT_DATE,
PAGE_ID,
SUM(NUM_VISITS) as pagehits
from
PAGEVISITS
where
VISIT_DATE >= '2015-01-01' and VISIT_DATE <= '2015-03-15'
group by
VISIT_DATE,
PAGE_ID
order by
VISIT_DATE, pagehits desc) sub
having row_num<5
Somehow the SQL fiddle shows kind of internal error when the query is executed.
