hi all,
i am new to t-sql i need to sum of the sales based on months and quarters together can some one help me to solve this.
CREATE TABLE [dbo].[tablesales2](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Name] [nchar](10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[cost] [numeric](18, 0) NULL,
[saledate] [datetime] NULL,
)
insert into [tablesales2](name,cost,saledate)values('pen',100,'01/01/2001')
insert into [tablesales2](name,cost,saledate)values('pencil',100,'01/01/2001')
insert into [tablesales2](name,cost,saledate)values('pen',200,'02/02/2001')
insert into [tablesales2](name,cost,saledate)values('pencil',200,'02/02/2001')

Hmmm.. try this:

; with cte as

(

SELECT name,cost , saledate ,

Quarter_Num = DATEPART(M ,[saledate] )

,Month_Name = LEFT ( DATENAME( M , [saledate]) , 3 )

FROM [dbo].[tablesales2]

)

SELECT

Name,

SUM ( CASE WHEN Month_Name = 'Jan' THEN Cost ELSE 0 END ) AS 'JAN' ,

SUM ( CASE WHEN Month_Name = 'Feb' THEN Cost ELSE 0 END ) AS 'FEB' ,

SUM ( CASE WHEN Month_Name = 'Mar' THEN Cost ELSE 0 END ) AS 'MAR' ,

SUM ( CASE WHEN Month_Name = 'Apr' THEN Cost ELSE 0 END ) AS 'APR' ,

SUM ( CASE WHEN Month_Name = 'May' THEN Cost ELSE 0 END ) AS 'MAY' ,

SUM ( CASE WHEN Month_Name = 'Jun' THEN Cost ELSE 0 END ) AS 'JUN' ,

SUM ( CASE WHEN Month_Name = 'Jul' THEN Cost ELSE 0 END ) AS 'JUL' ,

SUM ( CASE WHEN Month_Name = 'Aug' THEN Cost ELSE 0 END ) AS 'AUG' ,

SUM ( CASE WHEN Month_Name = 'Sep' THEN Cost ELSE 0 END ) AS 'SEP' ,

SUM ( CASE WHEN Month_Name = 'Oct' THEN Cost ELSE 0 END ) AS 'OCT' ,

SUM ( CASE WHEN Month_Name = 'Nov' THEN Cost ELSE 0 END ) AS 'NOV' ,

OOooch :pinch:, Mark beat me to it..

one variation between Mark and mine, i used DATENAME for the Month, he used DATEPART.. both do the same, infact, mark's is good one, considering the fact that we don't need that extra LEFT(,3) thingy 😉

thanks a lot both of you for your support , both solution works.

sayedkhalid99 Ten Centuries Points: 1394 More actions · Answer 7

one thing more is it possible to add total also at the bottom for each months and quarters , i tried to use union didn't work , do i need to add the results to temporary table then i have to aggregate the columns?

Try this:

Tweaked with the idea from Mark:

; with cte0 as

(

SELECT name,cost , saledate

,Quarter_Num = DATEPART(Q ,[saledate] )

,Month_Num = DATEPART(M ,[saledate] )

FROM [dbo].[tablesales2]

) -- SELECT * FROM cte0

, cte1 as

(

SELECT

Name,

SUM ( CASE WHEN Month_Num = 1 THEN Cost ELSE 0 END ) AS 'JAN' ,

SUM ( CASE WHEN Month_Num = 2 THEN Cost ELSE 0 END ) AS 'FEB' ,

SUM ( CASE WHEN Month_Num = 3 THEN Cost ELSE 0 END ) AS 'MAR' ,

SUM ( CASE WHEN Month_Num = 4 THEN Cost ELSE 0 END ) AS 'APR' ,

SUM ( CASE WHEN Month_Num = 5 THEN Cost ELSE 0 END ) AS 'MAY' ,

SUM ( CASE WHEN Month_Num = 6 THEN Cost ELSE 0 END ) AS 'JUN' ,

SUM ( CASE WHEN Month_Num = 7 THEN Cost ELSE 0 END ) AS 'JUL' ,

SUM ( CASE WHEN Month_Num = 8 THEN Cost ELSE 0 END ) AS 'AUG' ,

SUM ( CASE WHEN Month_Num = 9 THEN Cost ELSE 0 END ) AS 'SEP' ,

SUM ( CASE WHEN Month_Num = 10 THEN Cost ELSE 0 END ) AS 'OCT' ,

SUM ( CASE WHEN Month_Num = 11 THEN Cost ELSE 0 END ) AS 'NOV' ,

SUM ( CASE WHEN Month_Num = 12 THEN Cost ELSE 0 END ) AS 'DEC' ,

SUM ( CASE WHEN Quarter_Num = 1 THEN Cost ELSE 0 END ) AS 'Q1' ,

SUM ( CASE WHEN Quarter_Num = 2 THEN Cost ELSE 0 END ) AS 'Q2' ,

SUM ( CASE WHEN Quarter_Num = 3 THEN Cost ELSE 0 END ) AS 'Q3' ,

SUM ( CASE WHEN Quarter_Num = 4 THEN Cost ELSE 0 END ) AS 'Q4',

SUM ( Cost ) AS Total

It's probably most efficient to use the WITH ROLLUP clause, but I'm not at a computer where I can test it.

I finally had a chance to test this on a table with 18K records. Here are the results for producing a grand total:

WITH ROLLUP

Table 'Worktable'. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.

Table 'LEAD'. Scan count 1, logical reads 2428, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.

SQL Server Execution Times:

CPU time = 93 ms, elapsed time = 108 ms.

SQL Server parse and compile time:

CPU time = 63 ms, elapsed time = 63 ms.

Warning: Null value is eliminated by an aggregate or other SET operation.

UNION ALL

Table 'Worktable'. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.

Table 'LEAD'. Scan count 2, logical reads 4856, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.

SQL Server Execution Times:

CPU time = 187 ms, elapsed time = 209 ms.

As you can see, the UNION ALL has exactly double the number of Scan Counts and Logical Reads of the WITH ROLLUP.

Here is the query I used with the rollup.

SELECT CASE Grouping(Name) WHEN 1 THEN 'Total' ELSE Name END AS [Name],
