SQL Server Pivot and Sort - sql-server

Question

I have a shop order table with the Item code, description ReleaseDate and Required quantity.
How to query in a pivot table format in such a way that the results will be pivoted using Year+Month of [ReleaseDate] in sorting order from oldest date to latest date. Using the Year+Month as a column.
This is my query but it fails.
--Declare necessary variables
DECLARE #SQLQuery AS NVARCHAR(MAX)
DECLARE #PivotColumns AS NVARCHAR(MAX)
--Get unique values of pivot column
SELECT #PivotColumns = COALESCE(#PivotColumns + ',','') + QUOTENAME([YEARMONTH])
FROM (SELECT DISTINCT CONVERT(char(6), cast([releaseddate] as date), 112 ) as [YEARMONTH] FROM [dbo].[ShopOrder]) as PivotQuery
SELECT #PivotColumns
--Create the dynamic query with all the values for
--pivot column at runtime
SET #SQLQuery =
N'SELECT ItemCode, ' + #PivotColumns + '
FROM [dbo].[ShopOrder]
PIVOT( SUM(RequiredQty)
FOR [releaseddate] IN (' + #PivotColumns + ')) AS P'
SELECT #SQLQuery
--Execute dynamic query
EXEC sp_executesql #SQLQuery
This is the original record
Results query must be like this

Answer 1

Here I have tried to execute the pivot with your provided data.
Query
Select
[ItemCode],
[Description],
[2017/8],
[2017/9]
from
(
select cast(year(ReleasedDate) as nvarchar)+'/'+cast(month(ReleasedDate) as nvarchar) as ReleasedDate,ItemCode,Description,RequiredQty
from shoporder) as PivotData
Pivot
(
sum(RequiredQty) for ReleasedDate in
([2017/8],[2017/9])) as Pivoting
order by ItemCode
Output:
Fiddle

Answer 2

You are not pivoting correctly and the column names should be generated in a single string. Try this:
CREATE TABLE ShopOrder (ItemCode VARCHAR(100),[Description] VARCHAR(100),ReleaseDate DATE, RequiredQty INT)
GO
INSERT INTO ShopOrder
VALUES
('A','SLEEVE NUT','08/01/2017',19200)
,('A','SLEEVE NUT','08/02/2017',18000)
,('A','SLEEVE NUT','09/01/2017',17000)
,('B','STARTER','08/03/2017',10000)
,('B','STARTER','08/04/2017',18000)
,('B','STARTER','09/15/2017',16000)
DECLARE #SQLQuery AS NVARCHAR(MAX)
DECLARE #PivotColumns AS NVARCHAR(MAX)
SET #PivotColumns = STUFF(( SELECT DISTINCT ',[' + CONVERT(char(6), cast(ReleaseDate as date), 112 ) + ']'
FROM ShopOrder
ORDER BY ',[' + CONVERT(char(6), cast(ReleaseDate as date), 112 ) + ']'
FOR XML PATH('')),1,1,'')
SET #SQLQuery =
N'
SELECT ItemCode,'+ #PivotColumns + '
FROM (SELECT ItemCOde,CONVERT(char(6), cast(ReleaseDate as date),112) ReleaseDate, RequiredQty
FROM ShopOrder) AS T
PIVOT( SUM(RequiredQty)
FOR ReleaseDate IN ('+#PivotColumns+')) AS P
'
SELECT #SQLQuery
--Execute dynamic query
EXEC sp_executesql #SQLQuery
