I am using a ms sql stored procedure to get a set of records , when i am adding this stored procedure to my LinqToSql class and using it my repository it shows like it is returning a int value but it should be returning a set of rows. Is there some thing wrong with my stored procedure or some thing else???
ALTER PROCEDURE [dbo].[GetDocumentsAdvancedSearch]
-- Add the parameters for the stored procedure here
@SDI CHAR(10) = NULL
,@Client CHAR(4) = NULL
,@AccountNumber VARCHAR(20) = NULL
,@Address VARCHAR(300) = NULL
,@StartDate DATETIME = NULL
,@EndDate DATETIME = NULL
,@Job INT = NULL
,@Invoice INT = NULL
,@Amount MONEY = NULL

My guess would be that since the SQL is dynamic, LINQ isn’t able to determine exactly what the procedure will be returning.
Best workaround for this would probably be to just hand-edit the .dbml file
ETA: If you aren’t sure what to put in the .dbml file, another option might be to “trick” it into figuring out what you are returning from your sproc by putting some SQL inside a block that will never actually execute in practice:
