Error during PIVOT in SQL Server 2014 - sql

Question

I am trying to create pivot where row is Brand and SKU, sum is qty for column YYMM, but I'm not sure why it is throwing an error. Please help.
Code:
DECLARE #TABLE TABLE
(
SKU VARCHAR(10),
YYMM VARCHAR(50),
BRAND VARCHAR(50),
QTY INT
)
INSERT INTO #TABLE
SELECT '104591168', '2015-January', 'abott', 2 UNION ALL
SELECT '104580709', '2016-January', 'GSK', 2 UNION ALL
SELECT '104720038', '2017-January', 'RANBAXCY', 2 UNION ALL
SELECT '10467011A', '2018-January', 'abott', 2 UNION ALL
SELECT '104590691', '2019-January', 'abott', 10
Pivot code:
select *
from
(select
BRAND, sku, QTY, YYMM
from #TABLE) src
pivot
(sum(QTY)
for [Year Month]

Answer 1

You forgot to finish your query.
Please see the bottom of MSDN article for PIVOT examples.
I would guess that you wanted your query to look something like this:
SELECT *
FROM(
SELECT BRAND, sku, QTY, YYMM
FROM #TABLE
) AS src
PIVOT(
sum(QTY)
for [YYMM] IN( [2015-January], [2016-January], [2017-January] /* add other moneths here */ )
) AS Pivoted

Answer 2

We can make it as Dynamic sql
DECLARE #Column NVARCHAR(max),
#Column2 NVARCHAR(max),
#Sql NVARCHAR(max)
SELECT #Column = Stuff((SELECT DISTINCT ', '
+ Quotename(Cast(yymm AS VARCHAR(20)))
FROM #table
FOR xml path ('')), 1, 1, '')
SELECT #Column2 = Stuff((SELECT DISTINCT ', ' + 'ISNULL('
+ Quotename(Cast(yymm AS VARCHAR(20)))
+ ','
+ '''0''' + ') AS '
+ Quotename(Cast(yymm AS VARCHAR(20)))
FROM #table
FOR xml path ('')), 1, 1, '')
SET #Sql='
SELECT BRAND ,sku,'+#Column2+'
FROM(
SELECT *
FROM #TABLE
) AS src
PIVOT(
sum(QTY)
for [YYMM] IN('+#Column+')
) AS Pivoted
'
PRINT #Sql
EXEC(#Sql)
Result
BRAND sku 2015-January 2016-January 2017-January 2018-January 2019-January
