Executing Stored Procedure with Result Sets in SQL Server Denali

WITH RESULT SETS” is new enhanced feature comes with SQL Server “DENALI”. In many scenarios, we want to return the result sets from SP with changed column name and with different data type. In these cases we have been using Temporary table. 
Create temporary table, Insert data in temp table by executing Stored Procedure and display data from temp table, what if we can do it with simply executing stored procedure? Isn’t it awesome???
Yes, it is…. Now SQL Server Denali makes it possible. Let us see it how…..
–create Member’s personal detail table and insert data in it.
Create Table MemberPersonalDetail
(
MemberID INT Identity(1,1),
MemberName Varchar(20),
RegisterDate date,
ExpirationDate date
)
GO
INSERT INTO MemberPersonalDetail
SELECT ‘Ritesh Shah’,’01/01/2000′,’12/31/2015′ Union ALL
SELECT ‘Rajan Shah’,’02/07/2005′,’06/20/2011′ Union ALL
SELECT ‘Teerth Shah’,’06/22/2011′,’12/31/2015′
GO
SELECT * FROMMemberPersonalDetail
go
Now, I will make one simple stored procedure to return all columns of this table in SQL Server Denali CTP1 which we used to do since very long back. There is nothing new in this stored procedure.
CREATE PROC getMemberPersonalDetail
AS
      SELECT 
            MemberID
            ,MemberName
            ,RegisterDate
            ,ExpirationDate
      FROM
            MemberPersonalDetail
GO
After making this simple stored procedure, I will execute this stored procedure with regular method which we used to do and after that, I will execute the same stored procedure with “WITH RESULT SETS”,which will have changed column name of few column and changed data type of column.
–executing SP
EXECgetMemberPersonalDetail
GO
–Executing SP with “WITH RESULT SETS”
–MemberName will become “Name” from Varchar(20) to Varchar(6)
–both date column name will also be changed.
EXECgetMemberPersonalDetail
WITH RESULT SETS
(
      (
            ID INT,
            Name Varchar(6),
            DateOfRegistration date,
            DateOfExpiration date
      )
);
Here is the screen shot which shows results of both the execution of stored procedure.
