Getting error when dynamically unpivoting in SQL Server 2012 - sql-server

Question

The goal is to dynamically pivot data and then dynamically unpivot it.
I am getting an error saying Invalid ControlNo
I am assuming its because variable #colsUnpivot contains ControlNo column.
But how can I fix it? I definitely need that ControlNo.
IF OBJECT_ID('tempdb..##A') IS NOT NULL DROP TABLE ##A
IF OBJECT_ID('tempdb..#table1') IS NOT NULL DROP TABLE #table1
Create table #Table1 ( ControlNo INT, Bound INT, Declined INT, Rated INT, Quoted INT, QuoteStatus VARCHAR(50) )
INSERT INTO #Table1 (ControlNo, Bound, Declined, Rated, Quoted, QuoteStatus)
VALUES (1111,1,0,1,1,'Lost'),
(2222,0,1,0,1,'No Action'),
(3333,1,1,0,0,NULL),
(4444,1,0,0,1,'Lost'),
(5555,0,1,1,1,'No Action')
DECLARE #columns AS NVARCHAR(MAX),
#finalquery AS NVARCHAR(MAX);
SET #columns = STUFF((SELECT distinct ',' + QUOTENAME(QuoteStatus) FROM #Table1 FOR XML PATH(''), TYPE ).value('.', 'NVARCHAR(MAX)') ,1,1,'')
--PRINT #columns
set #finalquery = '
select p.controlno,
p.Bound,
p.Declined,
p.Rated,
p.Quoted,' + #columns + '
into ##A
from ( select ControlNo, Bound, Declined, Rated, Quoted, QuoteStatus
from #Table1
)a
pivot
(
COUNT(QuoteStatus)
for QuoteStatus IN (' + #columns + ')
)p '
exec(#finalquery)
--SELECT *
--FROM ##a
DECLARE #colsUnpivot AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #colsUnpivot
= stuff((select ','+quotename(C.name)
FROM tempdb.sys.columns c
WHERE c.object_id = OBJECT_ID('tempdb..##A')
for xml path('')), 1, 1, '')
--PRINT #colsUnpivot
set #query
= 'select ControlNo, Counts, Status
from ##A
unpivot
(
Counts
for Status in ('+ #colsunpivot +')
) u'
exec sp_executesql #query;
Output should look like this:

Answer 1

I assume your sample output was that, a sample, and you excluded the other control numbers. If so, changing the where clause in your stuff will remove that column from the unpivot group, and give you desired results. You can't return a column that you are pivoting or unpivoting.
IF OBJECT_ID('tempdb..##A') IS NOT NULL DROP TABLE ##A
IF OBJECT_ID('tempdb..#table1') IS NOT NULL DROP TABLE #table1
Create table #Table1 ( ControlNo INT, Bound INT, Declined INT, Rated INT, Quoted INT, QuoteStatus VARCHAR(50) )
INSERT INTO #Table1 (ControlNo, Bound, Declined, Rated, Quoted, QuoteStatus)
VALUES (1111,1,0,1,1,'Lost'),
(2222,0,1,0,1,'No Action'),
(3333,1,1,0,0,NULL),
(4444,1,0,0,1,'Lost'),
(5555,0,1,1,1,'No Action')
DECLARE #columns AS NVARCHAR(MAX),
#finalquery AS NVARCHAR(MAX);
SET #columns = STUFF((SELECT distinct ',' + QUOTENAME(QuoteStatus) FROM #Table1 FOR XML PATH(''), TYPE ).value('.', 'NVARCHAR(MAX)') ,1,1,'')
--PRINT #columns
set #finalquery = '
select p.controlno,
p.Bound,
p.Declined,
p.Rated,
p.Quoted,' + #columns + '
into ##A
from ( select *
from #Table1
)a
pivot
(
COUNT(QuoteStatus)
for QuoteStatus IN (' + #columns + ')
)p '
exec(#finalquery)
--SELECT *
--FROM ##a
DECLARE #colsUnpivot AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #colsUnpivot
= stuff((select ','+quotename(C.name)
FROM tempdb.sys.columns c
--notice i remove controlno here...
WHERE c.object_id = OBJECT_ID('tempdb..##A') and c.name <> 'controlno'
for xml path('')), 1, 1, '')
--PRINT #colsUnpivot
set #query
= 'select Controlno, Counts, Status
from ##A
unpivot
(
Counts
for Status in ('+ #colsunpivot +')
) u'
exec sp_executesql #query;
To get your exact output, then just add a where clause to the set #query.
set #query
= 'select Controlno, Counts, Status
from ##A
unpivot
(
Counts
for Status in ('+ #colsunpivot +')
) u
where controlno = 1111'
