I'm having a hard time getting the rows to group like needed. It gives me 4 rows instead of 1. I'm sure it's something simple, but I can't figure it out.
SELECT DISTINCT
th.name Serial,
CASE WHEN td.parameter = 4854455 THEN TRIM(LEADING '0' FROM td.text) ELSE NULL END Auto_PF,
CASE WHEN td.parameter = 797902 THEN TRIM(LEADING '0' FROM td.text) ELSE NULL END Auto_IC,
CASE WHEN td.parameter = 797402 THEN TRIM(LEADING '0' FROM td.text) ELSE NULL END Auto_NIC,
CASE WHEN td.parameter = 4854430 THEN TRIM(LEADING '0' FROM td.text) ELSE NULL END Auto_E46
FROM thisdata td
INNER JOIN this th
ON td.thisid = th.id
WHERE td.parameter IN ('4854455', '797902', '797402', '4854430', '6332168',
'6332160', '798102', '12000003', '12020956', '12020947', '12015253')
AND td.created >= (NOW() - INTERVAL 1 MONTH)
GROUP BY Serial, td.parameter, td.text
...
Result1
I think you should be aggregating only by the name, and then pivoting the CASE expressions:
SELECT
th.name Serial,
MAX(CASE WHEN td.parameter = 4854455 THEN TRIM(LEADING '0' FROM td.text) END) Auto_PF,
MAX(CASE WHEN td.parameter = 797902 THEN TRIM(LEADING '0' FROM td.text) END) Auto_IC,
MAX(CASE WHEN td.parameter = 797402 THEN TRIM(LEADING '0' FROM td.text) END) Auto_NIC,
MAX(CASE WHEN td.parameter = 4854430 THEN TRIM(LEADING '0' FROM td.text) END) Auto_E46
FROM thisdata td
INNER JOIN this th
ON td.thisid = th.id
WHERE
td.parameter IN ('4854455', '797902', '797402', '4854430', '6332168', '6332160',
'798102', '12000003', '12020956', '12020947', '12015253') AND
td.created >= (NOW() - INTERVAL 1 MONTH)
GROUP BY
th.name;

You could try using a join of the same table filter for null time_out and time_in
select a.dates, a.store_id, a,time_in, b.time_out
FROM attendance_store_user a
INNER JOIN attendance_store_user b on a.dates = b.dates

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%

Your case/when can be simplified, but I believe the killer of your query was the correlated NOT IN SELECT clause for your Opt-in request not sent.
I've change your query to do a left-join to your mailing table based on the contact AND the mailed status of "Y". So this simplifies your case to only have to check for IS NULL of the mailing table contact ID.
You can't do too much on performance since your Group by is by columns from different tables that won't take advantage of any index optimization, then all that ordered by the name makes it more of an issue... but the correlated subquery per the field being executed every time to a left-join SHOULD help.

CONCAT(CCD.CONTACT_FIRST_NAME, ' ', CCD.CONTACT_LAST_NAME) AS NAME,

I want to use Case When with AND condition and it is not calculating the sum properly.
For example:
SELECT DATE(`SubmitDate`),
SUM(CASE status WHEN 'New' AND `Type` = 'consumer' THEN 1 ELSE 0 END) as new_consumer,
SUM(CASE status WHEN 'New' AND `Type` = 'business' THEN 1 ELSE 0 END) as new_business
FROM report
WHERE `source` = 'net'
group by DATE(`SubmitDate`) Order by `SubmitDate` DESC
You need to use CASE WHEN [Condition] THEN... rather than a simple case expression:
SELECT DATE(`SubmitDate`),
SUM(CASE WHEN status = 'New' AND `Type` = 'consumer' THEN 1 ELSE 0 END) as new_consumer,
SUM(CASE WHEN status = 'New' AND `Type` = 'business' THEN 1 ELSE 0 END) as new_business
FROM report
WHERE `source` = 'net'
group by DATE(`SubmitDate`) Order by `SubmitDate` DESC
You should write
CASE WHEN status='New' AND `Type` = 'consumer' THEN 1 ELSE 0 END
Check the syntax of CASE WHEN
How do I get the Total value of Yes, No, Other fields of each username?
I like to add Total field.
SELECT Username,
SUM(CASE WHEN type = 'Yes' THEN 1 ELSE NULL END) as Yes,
SUM(CASE WHEN type = 'No' THEN 1 ELSE NULL END) as No,
SUM(CASE WHEN type = '' THEN 1 ELSE NULL END) as Other
//How to get total of Yes/No/Other
FROM table
WHERE source = 'CompanyName' ";
Also the highest Total goes at the top order.
use 0 instead of NULL, add the missing group by and use COUNT(*) to get the total of each group and order the result:
SELECT Username,
SUM(CASE WHEN type = 'Yes' THEN 1 ELSE 0 END) as Yes,
SUM(CASE WHEN type = 'No' THEN 1 ELSE 0 END) as No,
SUM(CASE WHEN type = '' THEN 1 ELSE 0 END) as Other,
COUNT(*) as TOTAL
FROM table
WHERE source = 'CompanyName'
group by Username
order by TOTAL desc;
This assumes that type can only be 'Yes', 'No' or ''.
Use a sub query to sum up your results and add a sort:
select yes, no, other, yes + no + other as Total
from (
SELECT Username,
SUM(CASE WHEN type = 'Yes' THEN 1 ELSE 0 END) as Yes,
SUM(CASE WHEN type = 'No' THEN 1 ELSE 0 END) as No,
SUM(CASE WHEN type = '' THEN 1 ELSE 0 END) as Other
FROM table
WHERE source = 'CompanyName'
)
order by (yes + no + other) desc
Don't use SUM(null), the SUM of (1,1,1,null) = null, not 3.
SELECT s.*, s.yes+s.no+s.other as all FROM (
SELECT Username,
SUM(CASE WHEN type = 'Yes' THEN 1 ELSE 0 END) as Yes,
SUM(CASE WHEN type = 'No' THEN 1 ELSE 0 END) as No,
SUM(CASE WHEN type = '' THEN 1 ELSE 0 END) as Other
FROM table
WHERE source = 'CompanyName'
GROUP BY Username
) s
ORDER BY all DESC
