In this blog I am going to show how we can generate a report using Pivot in SQL Server:

I want to dedicate this post to two of my friends cum brother Abhishek Nigam & Yogesh Gupta.

Abhishek Nigam & Yogesh Gupta If you see this post then I want to remember that beautiful day with both of you.

I got a business requirement to generate a report of Customer and their order detail by Month. Mean I have below 2 tables.

Customer:

  1. CREATE TABLE [dbo].[Customer](
  2. [Customer_ID] [int] IDENTITY(1,1) NOT NULL,
  3. [Customer_Name] [varchar](50) NULL,
  4. CONSTRAINT [PK_Customer] PRIMARY KEY CLUSTERED
  5. (
  6. [Customer_ID] ASC
  7. )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
  8. ) ON [PRIMARY]
  10. GO
  12. SET ANSI_PADDING OFF
  13. GO


  1. CREATE TABLE [dbo].[OrderDetails](
  2. [Order_ID] [int] IDENTITY(1,1) NOT NULL,
  3. [Customer_Name] [varchar](50) NULL,
  4. [Unit] [int] NULL,
  5. [Month] [varchar](50) NULL,
  6. CONSTRAINT [PK_OrderDetails] PRIMARY KEY CLUSTERED
  7. (
  8. [Order_ID] ASC
  9. )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
  10. ) ON [PRIMARY]
  12. GO
  14. SET ANSI_PADDING OFF
  15. GO


Select Records From both Tables:



Now I want to see records by Month mean in which month which customer order how many unit.

To get this write below query using PIVOT syntax in SQL Server:
  1. SELECT * FROM (
  2. SELECT c.Customer_Name, d.[Month],
  3. ISNULL(d.Unit,0) AS Unit
  4. FROm OrderDetails d RIGHT JOIN Customer c on d.Customer_Name=c.Customer_Name
  5. ) as s
  6. PIVOT
  7. (
  8. SUM(Unit)
  9. FOR [Month] in (January, February, March, April, May, June, July, August, September, October, November, December)
  10. ) As Pivot1
