Query optimization?

Question

Hello guys i had seprate 12 queries and some c# code to get the data formatted on the page, but now we are converted those pages to the SSRS reports. I have built the stored procedure which is combination of the 12 queries and some new additional queries to format the data as we want on the ssrs report. Now the new stored procedure is taking more time than the old page here is my query can any optimization possible on the following stored procedure any help would be great .

CREATE PROCEDURE [dbo].[GetHistoryByYear_Get] 
-- Add the parameters for the stored procedure here    
@Year AS VARCHAR(4),
@PreYear AS VARCHAR(4)

any help would be great i have indexed the tables and tables have lots of data it takes near about the 10 to 12 min to execute is there any way i can minimize it. and it's the SQL SERVER 2008 database

which is still takes time but is there any more optimization possible thanks

Answer 1

I think, you can try replace this

SELECT * FROM (
    SELECT @Year AS 'Year',Company, Customer,SUM(Jan) AS Jan, SUM(Feb) AS Feb, SUM(Mar) As Mar, SUM(Apr) AS Apr, SUM(May) AS May, SUM(Jun) AS Jun, SUM(Jul) AS Jul, SUM(Aug) AS Aug, SUM(Sep) AS Sep, SUM(Oct) AS Oct, SUM(Nov) AS Nov, SUM(Dec) AS Dec    
    ,(SUM(Jan) + SUM(Feb) + SUM(Mar) + SUM(Apr) + SUM(May) + SUM(Jun) + SUM(Jul) + SUM(Aug) + SUM(Sep) + SUM(Oct) + SUM(Nov) + SUM(Dec) ) AS YearlyTotal    
    FROM(    
        SELECT Company, Customer, DateRcvd, SUM(Records) AS Jan, 0 AS Feb, 0 As Mar, 0 As Apr, 0 As May, 0 As Jun, 0 As Jul, 0 As Aug, 0 As Sep, 0 As Oct, 0 As Nov, 0 As Dec    
        FROM(    
            select * from vwjmrep where datercvd >=@Year + '0101' and datercvd <= @Year + '1231' AND SUBSTRING(DateRcvd,5,2) = '01' AND Company IS NOT NULL    
            )  AS T    
        GROUP BY Company, Customer, DateRcvd    
        UNION    
        SELECT Company, Customer, DateRcvd, 0 AS Jan, SUM(RECORDS) AS Feb, 0 As Mar, 0 As Apr, 0 As May, 0 As Jun, 0 As Jul, 0 As Aug, 0 As Sep, 0 As Oct, 0 As Nov, 0 As Dec    
        FROM(    
            select * from vwjmrep where datercvd >=@Year + '0101' and datercvd <= @Year + '1231' AND SUBSTRING(DateRcvd,5,2) = '02' AND Company IS NOT NULL    
            )  AS T    
        GROUP BY Company, Customer, DateRcvd   

GROUP BY Company, Customer

with this

 SELECT @Year AS 'Year',Company, Customer,
    SUM(CASE WHEN SUBSTRING(DateRcvd,5,2) = '01' THEN Records ELSE 0 END) AS Jan,
    SUM(CASE WHEN SUBSTRING(DateRcvd,5,2) = '02' THEN Records ELSE 0 END) AS Feb,
    ...,
    SUM(Records) AS YearlyTotal    
    FROM  vwjmrep
WHERE datercvd >=@Year + '0101' and datercvd <= @Year + '1231'  AND Company IS NOT NULL 
GROUP BY Company, Customer

At least, there will be less Table Scans.

Answer 3

about my last comment:- I still go by it.Doing some stuff in sql and some in C# specially when query is so heavy .also your query do not have pagination.So no optmize query can help if it more than 100 rows.Also you hv to use index. Ok man check this out,if its not running then tell
