I have a query that works but in addition to what I already have I want to add one extra column for each category free,reduced,paid and certified free with the percentage compared to the total number of students. Can anyone help me?
select
count(case when Lunchstatus = 'P' then 1 else null end) as Paid
, count(case when LunchStatus = 'R' then 1 else null end) as Reduced
, count(case when LunchStatus = 'F' then 1 else null end) as Free
, count(case when LunchStatus = 'fdc' then 1 else null end) as CertifiedFree
, count(case when LunchStatus = 'P' then 1
when LunchStatus = 'fdc' then 1
when LunchStatus = 'R' then 1
when LunchStatus = 'F' then 1
else null
end) as Total
from students
where enroll_status = 0
and schoolid = %param1%
Treat you existing query as a derived table, cross join for the total count, then calculate your percentages:
select
d.*
, d.Paid * 100.0 / cj.totcount as paid_pct
... more like that
from (
select
count(case when Lunchstatus = 'P' then 1 else null end) as Paid
, count(case when LunchStatus = 'R' then 1 else null end) as Reduced
, count(case when LunchStatus = 'F' then 1 else null end) as Free
, count(case when LunchStatus = 'fdc' then 1 else null end) as CertifiedFree
, count(case when LunchStatus = 'P' then 1
when LunchStatus = 'fdc' then 1
when LunchStatus = 'R' then 1
when LunchStatus = 'F' then 1
else null
end) as Total
from students
where enroll_status = 0
and schoolid = %param1%
) d
CROSS JOIN (
select count(*) as totcount
from students
where enroll_status = 0
and schoolid = %param1%
) cj

I need count total register in a SQL table.
I have some status like this:
SELECT
COUNT(CASE WHEN status = 'WAITING_MEASUREMENT' THEN 1 ELSE NULL END) as '1',
COUNT(CASE WHEN status = 'WAITING_WEIGHMENT' THEN 1 ELSE NULL END) as '2',
COUNT(CASE WHEN status = 'WAITING_DATA_ENTRY' THEN 1 ELSE NULL END) as '3',
COUNT(CASE WHEN status = 'WAITING_PICTURES' THEN 1 ELSE NULL END) as '4'
FROM product;
But when I run query , i have a same result in all columns.
What's wrong in query?
You should sum instead of count and also use 0 instead of null, count will just count all the records.
SELECT
SUM(CASE WHEN status = 'WAITING_MEASUREMENT' THEN 1 ELSE 0 END) as '1',
SUM(CASE WHEN status = 'WAITING_WEIGHMENT' THEN 1 ELSE 0 END) as '2',
SUM(CASE WHEN status = 'WAITING_DATA_ENTRY' THEN 1 ELSE 0 END) as '3',
SUM(CASE WHEN status = 'WAITING_PICTURES' THEN 1 ELSE 0 END) as '4'
FROM product;
I want to display a table with SQL query like this:
I have run my query:
select
tb_r_orderdata.finishtime as date ,
count(*)sum all,
sum(when status = 'SUCCESS' and issync = '1' then 1 else 0 end) sumpaid,
sum(when status = 'SUCCESS' and issync in ('3', '4') then 1 else 0 end) sumfail,
sum(when status = 'CLOSED' then 1 else 0 end) sumclose,
sum(when status = 'Null' then 1 else 0 end) sumunflag
from
tb_r_orderdata;
But when I execute it, the result is different than what I expected. The result is like this:
Thank you for any help
You are missing the GROUP BY and the CASE:
select tb_r_orderdata.finishtime as date ,
COUNT(*) as sumall,
SUM(CASE WHEN status='SUCCESS' AND issync='1' then 1 ELSE 0 END) as sumpaid,
SUM(CASE WHEN status='SUCCESS' AND issync in ('3','4') then 1 ELSE 0 END) as sumfail,
SUM(CASE WHEN status='CLOSED' then 1 ELSE 0 END) as sumclose,
SUM(CASE WHEN status is null then 1 ELSE 0 END) as sumunflag
from tb_r_orderdata
group by tb_r_orderdata.finishtime ;
MySQL treats booleans as integers in a numeric context, with "1" for true and "0" for false. You can simplify your query to:
select o.finishtime as date ,
COUNT(*) as sumall,
SUM(status = 'SUCCESS' AND issync = '1') as sumpaid,
SUM(status = 'SUCCESS' AND issync in ('3', '4')) as sumfail,
SUM(status = 'CLOSED') as sumclose,
SUM(status is null) as sumunflag
from tb_r_orderdata o
where tb_r_orderdata.finishtime is not NULL
group by o.finishtime ;
This also removes NULL finish times.
Explanation in comment for Gordon Linoff
i have try your answer but there is record NULL in the top of table, i dont know why, can you explain it
with little bit change from Gordon Linoff answer
select tb_r_orderdata.finishtime as date ,
SUM(CASE WHEN status='SUCCESS' AND issync='1' then 1 ELSE 0 END) as sumpaid,
SUM(CASE WHEN status='SUCCESS' AND issync in ('3','4') then 1 ELSE 0 END) as sumfail,
SUM(CASE WHEN status='CLOSED' then 1 ELSE 0 END) as sumclose,
SUM(CASE WHEN status='NULL' then 1 ELSE 0 END) as sumunflag
from tb_r_orderdata
group by tb_r_orderdata.finishtime

How to get the sum of values for specific fields,i am getting the count of value but not getting the sum of value,what to do? help me if any body knows
You should use conditional aggregation inside the SUM too:
SELECT trtm,
COUNT(CASE WHEN trtm= 'TM' THEN 1 ELSE NULL END) AS Transmission,
COUNT(CASE WHEN trtm= 'TR' THEN 1 ELSE NULL END) AS Transfer,
COUNT(CASE WHEN trtm= 'DL' THEN 1 ELSE NULL END) AS Deletion
SUM(CASE WHEN trtm = 'TM' THEN tshares END) AS Total_Transmission,
SUM(CASE WHEN trtm = 'TR' THEN tshares END) AS Total_Transfer
FROM transfer_file
WHERE t_date between '10/1/1992' and '10/2/1992'
I have two dates, say start_date is 20141215 and end_date = 20150115. I would like to use SQL DATEDIFF to only count the dates within the year 2015 which I will specify in the query. Here is the current SQL I have written:
SELECT COUNT(leave_id),
sum(case when leave_status = 1 then 1 else 0 end) pending,
sum(case when leave_status = 2 then 1 else 0 end) declined,
sum(case when leave_status = 3 then 1 else 0 end) approved,
sum(case when leave_status = 4 then 1 else 0 end) rostered,
SUM(DATEDIFF(end_date, start_date)+1) as datetotals
FROM employee_leave WHERE
((YEAR(start_date) = :year) OR (YEAR(end_date) = :year))
AND employee_id = :emp_id
Thanks
You need to fix datediff() to only consider dates during the year. I think this does what you want:
SELECT COUNT(leave_id),
sum(case when leave_status = 1 then 1 else 0 end) pending,
sum(case when leave_status = 2 then 1 else 0 end) declined,
sum(case when leave_status = 3 then 1 else 0 end) approved,
sum(case when leave_status = 4 then 1 else 0 end) rostered,
SUM(DATEDIFF(least(end_date, date(concat_ws('-', :year, 12, 31))),
greatest(start_date, date(concat_ws('-', :year, 1, 1)))
) + 1) as datetotals
FROM employee_leave
WHERE ((YEAR(start_date) = :year) OR (YEAR(end_date) = :year)) AND
employee_id = :emp_id
Make it a AND condition rather like
WHERE
((YEAR(start_date) = :year) AND (YEAR(end_date) = :year))
I am using SUM ( CASE WHEN ) to count number of Yes and No, it work fine.
I am havin problem counting number of matching mobile number from two tables. It dont seem to be counting correctly.
There is a MobileNO field in dairy table and mobile field in the sales table
SELECT
D.Username,
SUM(CASE WHEN D.type = 'Yes' THEN 1 ELSE 0 END) as Yes,
SUM(CASE WHEN D.type = 'No' THEN 1 ELSE 0 END) as No,
SUM(CASE WHEN D.type = '' THEN 1 ELSE 0 END) as Other,
(SELECT SUM(CASE WHEN D.MobileNo = S.mobile THEN 1 ELSE 0 END) from sales as S) as Sales,
COUNT(*) as TOTAL FROM dairy as D
WHERE source = 'Company' AND UNIX_TIMESTAMP(CheckDate) >= 1293840000 AND UNIX_TIMESTAMP(CheckDate) <= 1322697600
group by D.Username order by TOTAL DESC
SELECT
D.Username,
SUM(CASE WHEN D.type = 'Yes' THEN 1 ELSE 0 END) as Yes,
SUM(CASE WHEN D.type = 'No' THEN 1 ELSE 0 END) as No,
SUM(CASE WHEN D.type = '' THEN 1 ELSE 0 END) as Other,
SUM(CASE WHEN S.mobile IS NULL THEN 0 ELSE 1 END) as Sales,
COUNT(*) as TOTAL
FROM dairy as D
LEFT JOIN (SELECT DISTINCT mobile FROM sales) as S ON D.MobileNo = S.mobile
WHERE source = 'Company' AND UNIX_TIMESTAMP(CheckDate) >= 1293840000 AND UNIX_TIMESTAMP(CheckDate) <= 1322697600
group by D.Username order by TOTAL DESC
