ALTER TABLE `tbldakmst`
ADD PRIMARY KEY (`inwardId`);
ALTER TABLE `tbldakmst` MODIFY `inwardId` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=8;
I have tried:
SELECT
sum(CASE
WHEN status = '1' THEN 1
ELSE 0
END) AS 'pending',
sum(CASE
WHEN status = '3' THEN 1
ELSE 0
END) AS 'initiated',
sum(CASE
WHEN status = '4' OR status = '5' THEN 1
ELSE 0
END) AS 'disposed' FROM tbldakmst
Above Query Output Was :
pending initiated disposed
2 1 3
<!-- Note:Status(0,1) ==>Pending ,Status (3) ==>Initiated,Status(4,5)==>Disposed
column FileInitiatedBy => User Value which one has initiated file.
Column disposedBy=> User Value which one has disposed file.
Column dakmarkTo => User Value which one have pending file -->
But I want Result Like this
User | Pending | Initiated | Disposed |
------------------------------------------------------
User 2 | 1 | 1 | 2 |
------------------------------------------------------
User 3 | 2 | 3 | 4 |
------------------------------------------------------

Answer 1

SELECT u.name AS 'Name',
sum(CASE
WHEN tb.status in ('0','1') AND (u.id = tb.dakMarkTo OR u.id = tb.createdBy) THEN 1
ELSE 0
END) AS 'pending' ,
sum(CASE
WHEN tb.status in ('3') AND u.id = tb.fileInitiateBy THEN 1
ELSE 0
END) AS 'initiated',
sum(CASE
WHEN tb.status in ('4', '5') AND u.id = tb.disposedBy THEN 1
ELSE 0
END) AS 'disposed'
FROM
tbldakmst tb, user u
group by u.name
