I am having 3 column field in mysql table id, status and count i want to get group of status and sum of count with distinct id value example is given below
id - status - count
1 - test1 - 1
1 - test1 - 1
1 - test2 - 1
1 - zer1 - 0
2 - exam1 - 1
2 - exam1 - 1
2 - zer2 - 0
2 - exam2 - 1
3 - mit1 - 1
3 - mit2 - 1
3 - zer3 - 0
4 - term1 - 1
i want the result like the following
id - status - count
1 - test1 - 2
2 - exam1 - 2
3 - mit1 - 1
4 - term1 - 1
i am tried the following query for the result but i didn't get the result
SELECT id,status,sum(count) as count FROM `test` where count=1 group by status order by id
for the above query i am getting the following result
id - status - count
1 test1 2
2 exam1 2
2 exam2 1
3 mit1 1
3 mit2 1
4 term1 1
i am unable to find the right query to remove the duplicate id's and order by sum of count.Please guide me to get the result.
You can use multiple query here like:
Select distinct id from
(SELECT id,status,
sum(count) as count
FROM `test` where count=1 group by status order by id
)
This is a tricky one because of two entries with id
3 having the same count
. However I think this query will do what you want:
SELECT c1.id, MIN(c1.status) AS status, c1.sum_c
FROM (SELECT id, status, SUM(`count`) AS sum_c
FROM `counts`
GROUP BY id, status
) c1
JOIN (SELECT id, MAX(sum_c) AS max_c
FROM (SELECT id, status, SUM(`count`) AS sum_c
FROM `counts`
GROUP BY id, status
) c1
GROUP BY id) c2
ON c2.id = c1.id AND c2.max_c = c1.sum_c
GROUP BY c1.id
Output:
id status sum_c
1 test1 2
2 exam1 2
3 mit1 1
4 term1 1
Try below using subquery:
select t2.id, b.status, t2.scount
from
(SELECT id,max(scount) as scount
FROM
(
SELECT id,status,sum(count) as scount
FROM t where count=1
group by status,id
)a group by id) t2
inner join
(
SELECT id,status,sum(count) as scount
FROM t where count=1
group by status,id
)b on t2.id =b.id and t2.scount=b.scount
use co-related sub-query
select min(status) status,id,s as count from
(
select * from
(
select id,status,sum(cnt) s from t
where cnt>0
group by id,status
) as t1 where t1.s in( select max(s) from
(select status,id,sum(cnt) s from t
where cnt>0
group by
status,id) t2 where t1.id=t2.id
group by t2.id
)
) as t3 group by id,s
