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
FROM tbluserscenescores) AS results

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
When I run the following query.
SELECT tblhostingaddons.id as id,
MAX(CASE WHEN (tblcustomfields.fieldname = 'boyut') THEN tblcustomfields.fieldoptions ELSE NULL END) AS quota,
MAX(CASE WHEN (tblcustomfields.fieldname = 'adet') THEN tblcustomfields.fieldoptions ELSE NULL END) AS pc,
MAX(CASE WHEN (tblcustomfields.fieldname = 'gonderimlimiti') THEN tblcustomfields.fieldoptions ELSE NULL END) AS send,
MAX(CASE WHEN (tblcustomfields.fieldname = 'turu') THEN tblcustomfields.fieldoptions ELSE NULL END) AS type
FROM `tblhostingaddons`
LEFT JOIN tbladdons ON tbladdons.id = tblhostingaddons.addonid
LEFT JOIN tblcustomfields ON tblcustomfields.relid = tbladdons.id
WHERE tblhostingaddons.hostingid = '88'
AND tblhostingaddons.status = 'Active'
GROUP BY tblhostingaddons.id
ORDER BY tblhostingaddons.id
The following result comes up. But I just want the type to come in lines that are epostapro.
id quota pc send type
74 5120 1 200 epostapro
75 NULL NULL NULL NULL
Try using having clause:
SELECT tblhostingaddons.id as id,
MAX(CASE WHEN (tblcustomfields.fieldname = 'boyut') THEN tblcustomfields.fieldoptions ELSE NULL END) AS boyut,
MAX(CASE WHEN (tblcustomfields.fieldname = 'adet') THEN tblcustomfields.fieldoptions ELSE NULL END) AS adet,
MAX(CASE WHEN (tblcustomfields.fieldname = 'gonderimlimiti') THEN tblcustomfields.fieldoptions ELSE NULL END) AS gonderimlimiti,
MAX(CASE WHEN (tblcustomfields.fieldname = 'turu') THEN tblcustomfields.fieldoptions ELSE NULL END) AS turu
FROM `tblhostingaddons`
LEFT JOIN tbladdons ON tbladdons.id = tblhostingaddons.addonid
LEFT JOIN tblcustomfields ON tblcustomfields.relid = tbladdons.id
WHERE tblhostingaddons.hostingid = '88'
AND tblhostingaddons.status = 'Active'
GROUP BY tblhostingaddons.id
having MAX(CASE WHEN (tblcustomfields.fieldname = 'turu') THEN tblcustomfields.fieldoptions ELSE NULL END)='epostapro'
ORDER BY tblhostingaddons.id
OR you can remove id from selection list as well as group by
like below:
SELECT
MAX(CASE WHEN (tblcustomfields.fieldname = 'boyut') THEN tblcustomfields.fieldoptions ELSE NULL END) AS boyut,
MAX(CASE WHEN (tblcustomfields.fieldname = 'adet') THEN tblcustomfields.fieldoptions ELSE NULL END) AS adet,
MAX(CASE WHEN (tblcustomfields.fieldname = 'gonderimlimiti') THEN tblcustomfields.fieldoptions ELSE NULL END) AS gonderimlimiti,
MAX(CASE WHEN (tblcustomfields.fieldname = 'turu') THEN tblcustomfields.fieldoptions ELSE NULL END) AS turu
FROM `tblhostingaddons`
LEFT JOIN tbladdons ON tbladdons.id = tblhostingaddons.addonid
LEFT JOIN tblcustomfields ON tblcustomfields.relid = tbladdons.id
WHERE tblhostingaddons.hostingid = '88'
AND tblhostingaddons.status = 'Active'
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.

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.

Anybody can convert this query to active record codeigniter???
SELECT b.name,
SUM(CASE WHEN c.size = 'S' THEN 1 ELSE 0 END) S,
SUM(CASE WHEN c.size = 'M' THEN 1 ELSE 0 END) M,
SUM(CASE WHEN c.size = 'L' THEN 1 ELSE 0 END) L,
SUM(CASE WHEN c.size = 'XL' THEN 1 ELSE 0 END) XL
FROM orderTB a
INNER JOIN productTB b
ON a.id_product = b.id_shirt
INNER JOIN sizeTB c
ON a.id_size = c.id_size
GROUP BY b.name
i've tried like this
function get()
{
$this->db->select("b.name,SUM(CASE WHEN c.size ='S' THEN 1 ELSE 0 END) as S,SUM(CASE WHEN c.size = 'M' THEN 1 ELSE 0 END) as M,SUM(CASE WHEN c.size = 'L' THEN 1 ELSE 0 END) as L,SUM(CASE WHEN c.size = 'XL' THEN 1 ELSE 0 END) as XL");
$this->db->from('order');
$this->db->join('ukuran','order.id_size=ukuran.id_size');
$this->db->where('date',$date);
return $this->db->get();
}
but its wrong
Just try this one and let me know,
$this->db->select("b.name,SUM(CASE WHEN c.size = 'S' THEN 1 ELSE 0 END) S,SUM(CASE WHEN c.size = 'M' THEN 1 ELSE 0 END) M,SUM(CASE WHEN c.size = 'L' THEN 1 ELSE 0 END) L,SUM(CASE WHEN c.size = 'XL' THEN 1 ELSE 0 END) XL", FALSE );
$this->db->from('orderTB a');
$this->db->join('productTB b','a.id_product = b.id_shirt','inner');
$this->db->join('sizeTB c','a.id_size = c.id_size','inner');
$this->db->group_by('b.name');
From document here
$this->db->select() accepts an optional second parameter. If you set
it to FALSE, CodeIgniter will not try to protect your field or table
names with backticks. This is useful if you need a compound select
statement.
EDIT
Just add FALSE in your select statement
function get() {
$this->db->select("b.name,SUM(CASE WHEN c.size ='S' THEN 1 ELSE 0 END) as S,SUM(CASE WHEN c.size = 'M' THEN 1 ELSE 0 END) as M,SUM(CASE WHEN c.size = 'L' THEN 1 ELSE 0 END) as L,SUM(CASE WHEN c.size = 'XL' THEN 1 ELSE 0 END) as XL",FALSE);
