I want to ask about mysql with rollup only get rollup value, this is my code
SELECT tbldept.CodeDept AS Dept,
SUM(CASE WHEN tblemp.Status = '1' THEN 1 ELSE 0 END) AS headcount,
SUM(CASE WHEN tblemp.Status = '1' THEN 1 ELSE 0 END) * 144 AS RegHrsEst,
CONCAT(ROUND(20), '%') AS TargetOT,
round(SUM(CASE WHEN tblemp.Status = '1' THEN 1 ELSE 0 END) * 144 * 0.2) AS OTHrsBdgt
FROM tbldept
LEFT JOIN tblemp
ON tbldept.CodeDept = tblemp.CodeDept AND
tblemp.class = "DIR"
WHERE tbldept.CodeDept != 'FIN' AND
tbldept.CodeDept != 'HRT' AND
tbldept.CodeDept != 'ISD'
GROUP BY tbldept.CodeDept with ROLLUP;
result of rollup query:
how can i only get the rollup values? Thanks before
If you just want the row of rollup, simply use having:
SELECT tbldept.CodeDept AS Dept,
SUM(CASE WHEN tblemp.Status = '1' THEN 1 ELSE 0 END) AS headcount,
SUM(CASE WHEN tblemp.Status = '1' THEN 1 ELSE 0 END) * 144 AS RegHrsEst,
CONCAT(ROUND(20), '%') AS TargetOT,
round(SUM(CASE WHEN tblemp.Status = '1' THEN 1 ELSE 0 END) * 144 * 0.2) AS OTHrsBdgt
FROM tbldept
LEFT JOIN tblemp
ON tbldept.CodeDept = tblemp.CodeDept AND
tblemp.class = "DIR"
WHERE tbldept.CodeDept != 'FIN' AND
tbldept.CodeDept != 'HRT' AND
tbldept.CodeDept != 'ISD'
GROUP BY tbldept.CodeDept with ROLLUP
HAVING Dept IS NULL;
Edit:
having should work, check if there are some other reasons exist or not.
Or just wrap your query with a subquery:
SELECT *
FROM (
SELECT tbldept.CodeDept AS Dept,
SUM(CASE WHEN tblemp.Status = '1' THEN 1 ELSE 0 END) AS headcount,
SUM(CASE WHEN tblemp.Status = '1' THEN 1 ELSE 0 END) * 144 AS RegHrsEst,
CONCAT(ROUND(20), '%') AS TargetOT,
round(SUM(CASE WHEN tblemp.Status = '1' THEN 1 ELSE 0 END) * 144 * 0.2) AS OTHrsBdgt
FROM tbldept
LEFT JOIN tblemp
ON tbldept.CodeDept = tblemp.CodeDept AND
tblemp.class = "DIR"
WHERE tbldept.CodeDept != 'FIN' AND
tbldept.CodeDept != 'HRT' AND
tbldept.CodeDept != 'ISD'
GROUP BY tbldept.CodeDept with ROLLUP
) t
WHERE Dept IS NULL;

My Query :
SELECT
(ref_intake.intakeno) AS intake,
SUM(CASE WHEN(student.intakeid AND student.status = '3' AND (student.courseid=3 OR student.courseid=17)) THEN 1 else 0 END) as active,
SUM(CASE WHEN(student.intakeid AND student.status = '5' AND (student.courseid=3 OR student.courseid=17)) THEN 1 else 0 END) as deffered,
SUM(CASE WHEN(student.intakeid AND student.status = '16' AND (student.courseid=3 OR student.courseid=17)) THEN 1 else 0 END) as inactive,
SUM(CASE WHEN(student.intakeid AND student.status = '9' AND (student.courseid=3 OR student.courseid=17)) THEN 1 else 0 END) as missing,
SUM(CASE WHEN(student.intakeid AND student.status = '6' AND (student.courseid=3 OR student.courseid=17)) THEN 1 else 0 END) as widthdrawn,
SUM(CASE WHEN(student.intakeid AND student.status IN (18,7,36) AND (student.courseid=3 OR student.courseid=17)) THEN 1 else 0 END) as dis_ter_dereg
FROM student
LEFT JOIN ref_intake ON student.intakeid = ref_intake.intakeid
GROUP BY student.intakeid ORDER BY ref_intake.intakeno ASC
The the image is my result:
I do suspect that your query can be simplified as follows:
SELECT
s.intakeid AS intake,
SUM(CASE WHEN s.status = 3 THEN 1 ELSE 0 END) as active,
SUM(CASE WHEN s.status = 5 THEN 1 ELSE 0 END) as deffered,
SUM(CASE WHEN s.status = 16 THEN 1 ELSE 0 END) as inactive,
SUM(CASE WHEN s.status = 9 THEN 1 ELSE 0 END) as missing,
SUM(CASE WHEN s.status = 6 THEN 1 ELSE 0 END) as widthdrawn,
SUM(CASE WHEN s.status IN (18, 7, 36) THEN 1 ELSE 0 END) as dis_ter_dereg
FROM student s
INNER JOIN ref_intake ri ON s.intakeid = ri.intakeid
WHERE
s.intakeid
AND s.status IN (3, 5, 16, 9, 6, 18, 7, 36)
AND s.courseid IN (3, 17)
GROUP BY s.intakeid
ORDER BY ri.intakeno ASC
That is:
most conditions can be moved to the WHERE clause - this should actually remove rows where no condition matches
it seems like you actually want an INNER JOIN rather than a LEFT JOIN - but you can revert that change if needed
table aliases make the query easier to read and write
ORed conditions can be simplified to use IN
How can I do a "union" in order to get only distinct values for "ACTIVITY" field, but with the variables started by "OUTPUT_" from "OUTPUT_TAB" appearing in the header. (Like "INPUT_" variables from "INPUT_TAB") .
It's possible ? I can not do it.

In case there can be input without output or vice versa, you'll have to use an outer join instead. In case there can even be both, input without output and output without input, you'll have to look up how to emulate a full outer join in MySQL.
I've removed CASE WHEN .. THEN 1 ELSE 0 END, because a boolean expression results in true or false which equal to 1 and 0 in MySQL.
BTW: As this is all about 2017, you can get your queries simpler and faster by using WHERE YEAR(data_val_registo) and WHERE YEAR(data_fim_rep) = 2017 and removing the condition from the sum expressions.
I have two tables and i wanted data should come in specific format.
My query
SELECT
DISTINCT ur.suid,
(CASE WHEN ur.sceneID = '1' THEN ur.data ELSE 0 END) AS Scenario1data,
(CASE WHEN ur.sceneID = '1' THEN ss.score ELSE 0 END) AS Scenario1score,
(CASE WHEN ur.sceneID = '2' THEN ur.data ELSE 0 END) AS Scenario2,
(CASE WHEN ur.sceneID = '3' THEN ur.data ELSE 0 END) AS Scenario3,
(CASE WHEN ur.sceneID = '4' THEN ur.data ELSE 0 END) AS Scenario4
FROM tbluserresults AS ur LEFT JOIN tbluserscenescores AS ss ON ss.suid = ur.suid;
Result i wanted
suid Scenario1data Scenario1score Scenario2 Scenario3 Scenario4
1 'abc show1' 334 abc show2 abc show3 abc show 4
2 0 0 0 0.
Check my SQLFIDDLE
There are probably other better ways to do this, but I believe the following does what you want
SELECT results.suid as suid,
(CASE WHEN results.Scenario1data IS NOT NULL THEN results.Scenario1data ELSE 0 END) AS Scenario1data,
(CASE WHEN results.Scenario1score IS NOT NULL THEN results.Scenario1score ELSE 0 END) AS Scenario1score,
(CASE WHEN results.Scenario2 IS NOT NULL THEN results.Scenario2 ELSE 0 END) AS Scenario2,
(CASE WHEN results.Scenario3 IS NOT NULL THEN results.Scenario3 ELSE 0 END) AS Scenario3,
(CASE WHEN results.Scenario4 IS NOT NULL THEN results.Scenario4 ELSE 0 END) AS Scenario4
FROM
(SELECT DISTINCT(suid), #suid:= suid,
(SELECT ur.data FROM tbluserresults ur WHERE ur.suid = #suid AND ur.sceneID = '1') AS Scenario1data,
(SELECT ss.score FROM tbluserscenescores ss WHERE ss.suid = #suid AND ss.sceneID = '1') AS Scenario1score,
(SELECT ur.data FROM tbluserresults ur WHERE ur.suid = #suid AND ur.sceneID = '2') AS Scenario2,
(SELECT ur.data FROM tbluserresults ur WHERE ur.suid = #suid AND ur.sceneID = '3') AS Scenario3,
(SELECT ur.data FROM tbluserresults ur WHERE ur.suid = #suid AND ur.sceneID = '4') AS Scenario4

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.

Is it possible to combine these two queries into one query?
SELECT sum(amount) as credit FROM statement WHERE userId= '33003' AND debitOrCredit = '1' AND actionDate <= '2012-10-17';
SELECT sum(amount) as debit FROM statement WHERE userId= '33003' AND debitOrCredit = '0' AND actionDate <= '2012-10-17';
so I get the result:
| credit | debit |
| 90 | 60 |
You could use CASE within your SUM:
SELECT sum(CASE WHEN debitOrCredit = '1' THEN amount ELSE 0 END) as credit,
sum(CASE WHEN debitOrCredit = '0' THEN amount ELSE 0 END) as debit
FROM statement WHERE userId= '33003' AND actionDate <= '2012-10-17';
use CASE in your SELECT clause
SELECT sum(CASE WHEN debitOrCredit = '1' THEN amount ELSE 0 END) as credit,
sum(CASE WHEN debitOrCredit = '0' THEN amount ELSE 0 END) as debit
FROM statement
WHERE userId= '33003' AND
actionDate <= '2012-10-17';
Use like this.
SELECT sum(a.amount) as credit,sum(b.amount) as debit FROM statement a left join statement b
on a.userId=b.userId
WHERE a.userId= '33003' AND a.debitOrCredit = '1' AND b.debitOrCredit = '0' AND a.actionDate <= '2012-10-17' AND b.actionDate <= '2012-10-17' ;
-- Mark answered if this answer answers your question...
Thank you for your help.
This is how I used it in Zend framework:
$sql = $this->_dba->select()
->from('statement', array(
"credit" => "sum(CASE WHEN debitOrCredit = '1' THEN amount ELSE 0 END)",
"debit" => "sum(CASE WHEN debitOrCredit = '0' THEN amount ELSE 0 END)"))
->where('userId = ?', $userId)
->where('actionDate <= ?', $date);
try
{
$result = $this->db->fetchRow($sql);
//process result here
}
catch (Exception $e)
{
throw new Exception("Error on ...... ");
}
Try this
SELECT sum(case when debitOrCredit = '1' then amount else 0 end) as credit, sum(case when debitOrCredit = '2' then amount else 0 end) as debit FROM statement WHERE userId= '33003' AND actionDate <= '2012-10-17'
