Question

I'm trying to convert my result table which consist of multiple rows into multiple columns. below are my sample result before and after:
Before:
After:
Got a some idea from here but still no luck.
Update 1:
select #cols = STUFF((select ',' + QUOTENAME(institution) + ',' + QUOTENAME(intstatus)
From #temp
group by refno,frmstatus
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'),1,1,'')
i have no idea how to insert each column into the pivot query
set #query = 'select refno, frmstatus,' + #cols + '
from (
select refno, frmstatus, institution, intstatus from #temp
) x
pivot
(
???????
)

Answer 1

Please try the below query:
CREATE TABLE #temp(refno nvarchar(20), firmstatus nvarchar(20), institution nvarchar(20), intstatus nvarchar(20), ranking int)
DECLARE #qu NVARCHAR(MAX), #pcol NVARCHAR(MAX)
INSERT INTO #temp
SELECT
*,
ROW_NUMBER() OVER (PARTITION BY refno ORDER BY institution ASC) AS ranking
FROM temp
SELECT #pcol=
STUFF((
SELECT
DISTINCT N', Institution'+ CAST (ranking AS NVARCHAR(25)) +', '+ N'Intstatus'+ CAST (ranking AS NVARCHAR(25))
FROM #temp
FOR XML PATH('')),1,1,'')
SET #qu=N'SELECT refno, firmstatus,'+ #pcol +
N' FROM
(
select refno,firmstatus,ColData,colheader+ CAST(ranking as varchar) as colnames from
(select * from #temp)s
UNPIVOT
(ColData for colheader in ([institution], [intstatus])) up
)S
PIVOT
(MAX(ColData) FOR colnames IN ('+#pcol +N')) AS piv'
EXEC sp_executesql #qu -- execute the dynamic sql
DROP TABLE #temp -- remove the temp table
The temp table in above script was created like below
--create table temp( refno nvarchar(20), firmstatus nvarchar(20), institution nvarchar(20), intstatus nvarchar(20))
--insert into temp values
--('AAA/1','Active','InstA','Ongoing'),
--('AAA/1','Active','InstB','Ongoing'),
--('AAA/1','Active','InstC','Ongoing'),
--('AAA/2','Active','InstA','Ongoing'),
--('AAA/2','Active','InstB','Ongoing')
Result received:

If repeated columns number is small and restricted, you can use simple solution:
WITH A AS (
SELECT *,
ROW_NUMBER() OVER(PARTITION BY refno, fmstatus ORDER BY institution) n
FROM myTable
),
B AS (
SELECT refno, fmstatus,
CASE WHEN n=1 THEN institution END institution,
CASE WHEN n=1 THEN intstatus END intstatus,
CASE WHEN n=2 THEN institution END institution1,
CASE WHEN n=2 THEN intstatus END intstatus1,
CASE WHEN n=3 THEN institution END institution2,
CASE WHEN n=3 THEN intstatus END intstatus2
FROM A
)
SELECT refno, fmstatus,
MAX(institution) institution,
MAX(intstatus) intstatus,
MAX(institution1) institution1,
MAX(intstatus1) intstatus1,
MAX(institution2) institution2,
MAX(intstatus2) intstatus2
FROM B
GROUP BY refno, fmstatus
Otherwise use PIVOT
