improve execution Time of stored procedure

  • Hi,

    I have created 1 stored procedure for down loading the products into excel file from the data base.In this stored procedure,fields are selecting from 4 data base tables.This stored procedure is a simple select statement, but selecting 72

    fields from 4 database tables.The problem is that , this stored procedure is taking too much time for executing.

    My data base having more than 2,00,000 products.Now this stored procedure is trying to down load maximum 5000 products at a time.In local application it is taking maximum 5 seconds. But in server, this is taking more than 12 minutes.

    In future, my client want to down load lacks of products at a time. So please give me an advice to solve this problem

    This is the stored procedure, that I have written

    ALTER procedure [dbo].[CMRC_SP_ProductDetails](@merchantID INT)

    AS

  • Can you show the execution plan for this query? Output it as XML and attach it to a post.

    You may want to look at SSIS as a mechanism for moving large amounts of data around.

  • I'd definitely think SSIS if this is data movement, as in download or transfer to another server.

    If not, get the plan, be sure things are indexed properly, and I might suck out the list to a temp table without the left join, then add in the left join as a second step.
