Dynamic SQL Query for Date Column

Dec 26, 2019 07:53 AM|umerfaiz123@outlook.com|LINK

This is the source https://www.sqlrelease.com/dynamic-pivot-query-in-sql-server

From the above instead of customer column i would to pivot using date column. Let me know how to do so?

Table

CREATE TABLE [dbo].[ShoppingDetail](
	[CustomerName] [varchar](256) NOT NULL,
	[ProductCategory] [varchar](256) NOT NULL,
	[TotalAmount] [numeric](18, 2) NOT NULL,
	[Date] [date] NULL
) ON [PRIMARY]
GO

INSERT [dbo].[ShoppingDetail] ([CustomerName], [ProductCategory], [TotalAmount], [Date]) VALUES (N'Roy Martin', N'Clothing', CAST(2967.00 AS Numeric(18, 2)), CAST(N'2019-12-10' AS Date))
INSERT [dbo].[ShoppingDetail] ([CustomerName], [ProductCategory], [TotalAmount], [Date]) VALUES (N'Roy Martin', N'Accessories', CAST(2458.00 AS Numeric(18, 2)), CAST(N'2019-12-10' AS Date))
INSERT [dbo].[ShoppingDetail] ([CustomerName], [ProductCategory], [TotalAmount], [Date]) VALUES (N'Roy Martin', N'Bikes', CAST(52478.00 AS Numeric(18, 2)), CAST(N'2019-12-10' AS Date))
INSERT [dbo].[ShoppingDetail] ([CustomerName], [ProductCategory], [TotalAmount], [Date]) VALUES (N'Caitlin C Watson', N'Clothing', CAST(3289.00 AS Numeric(18, 2)), CAST(N'2019-12-11' AS Date))
INSERT [dbo].[ShoppingDetail] ([CustomerName], [ProductCategory], [TotalAmount], [Date]) VALUES (N'Caitlin C Watson', N'Bikes', CAST(75769.00 AS Numeric(18, 2)), CAST(N'2019-12-14' AS Date))
INSERT [dbo].[ShoppingDetail] ([CustomerName], [ProductCategory], [TotalAmount], [Date]) VALUES (N'Taylor Torres', N'Clothing', CAST(2875.00 AS Numeric(18, 2)), CAST(N'2019-12-14' AS Date))
INSERT [dbo].[ShoppingDetail] ([CustomerName], [ProductCategory], [TotalAmount], [Date]) VALUES (N'Taylor Torres', N'Accessories', CAST(6567.00 AS Numeric(18, 2)), CAST(N'2019-12-10' AS Date))
INSERT [dbo].[ShoppingDetail] ([CustomerName], [ProductCategory], [TotalAmount], [Date]) VALUES (N'Taylor Torres', N'Bikes', CAST(46897.00 AS Numeric(18, 2)), CAST(N'2019-12-11' AS Date))
INSERT [dbo].[ShoppingDetail] ([CustomerName], [ProductCategory], [TotalAmount], [Date]) VALUES (N'Taylor Torres', N'Food Products', CAST(15783.00 AS Numeric(18, 2)), CAST(N'2019-12-14' AS Date))

Instead of customer in need date column pivot

DECLARE @SQLStatement NVARCHAR(MAX) = N'' --Variable to hold t-sql query
DECLARE @UniqueCustomersToPivot NVARCHAR(MAX) = N'' --Variable to hold unique customers to be used in PIVOT clause
DECLARE @PivotColumnsToSelect NVARCHAR(MAX) = N'' --Variable to hold pivot column names with alias to be used in SELECt clause
--Extarct unique customer names with pivot formattings
SELECT @UniqueCustomersToPivot = @UniqueCustomersToPivot + ', [' + COALESCE(CustomerName, '') + ']' FROM (SELECT DISTINCT CustomerName FROM dbo.ShoppingDetail)DT
SELECT @UniqueCustomersToPivot = LTRIM(STUFF(@UniqueCustomersToPivot, 1, 1, '')) --Remove first comma and space
--Generate column names to be put in SELECT list with NULL handling and aliases also
SELECT @PivotColumnsToSelect = @PivotColumnsToSelect + ', ISNULL([' + COALESCE(CustomerName, '') + '], 0) AS [' + CustomerName + ']'
FROM (SELECT DISTINCT CustomerName FROM dbo.ShoppingDetail)DT
--Generate dynamic PIVOT query here
SET @SQLStatement =
N'SELECT ProductCategory '
+ @PivotColumnsToSelect +
'
FROM dbo.ShoppingDetail
PIVOT
(
SUM(TotalAmount) FOR
CustomerName IN
(' + @UniqueCustomersToPivot + ')
) AS PVT

Pivot query

The query result of above query you provided is:

According to the description, you want [date] as your query result's fields instead of [CustomerName] if i didn't misunderstand anything which should looks like below?

If so, you just need to change some little parts of your current query code:

DECLARE @SQLStatement NVARCHAR(MAX) = N'' --Variable to hold t-sql query
DECLARE @UniqueCustomersToPivot NVARCHAR(MAX) = N'' --Variable to hold unique customers to be used in PIVOT clause
DECLARE @PivotColumnsToSelect NVARCHAR(MAX) = N'' --Variable to hold pivot column names with alias to be used in SELECt clause
--Extarct unique customer names with pivot formattings
SELECT @UniqueCustomersToPivot = @UniqueCustomersToPivot + ', [' + COALESCE(convert(varchar(50),[Date]), '') + ']' FROM (SELECT DISTINCT [Date] FROM dbo.ShoppingDetail)DT
SELECT @UniqueCustomersToPivot = LTRIM(STUFF(@UniqueCustomersToPivot, 1, 1, '')) --Remove first comma and space
--Generate column names to be put in SELECT list with NULL handling and aliases also
SELECT @PivotColumnsToSelect = @PivotColumnsToSelect + ', ISNULL([' + COALESCE(convert(varchar(50),[Date]), '') + '], 0) AS [' + convert(varchar(50),[Date]) + ']'
FROM (SELECT DISTINCT [Date] FROM dbo.ShoppingDetail)DT
--Generate dynamic PIVOT query here
SET @SQLStatement =
N'SELECT ProductCategory '
+ @PivotColumnsToSelect +
'
FROM dbo.ShoppingDetail
PIVOT
(
SUM(TotalAmount) FOR
[Date] IN
(' + @UniqueCustomersToPivot + ')
) AS PVT
'
--Execute the dynamic t-sql PIVOT query below
EXEC (@SQLStatement)

Or if i misunderstood anything please feel free to tell.
