EF与Stored Proc 连用 Collection

=======Example 1.

Stored Proc

USE [InstagramData]

GO
/****** Object:  StoredProcedure [dbo].[CreateTempTableForPostIdWithIdentity]    Script Date: 2014/12/5 15:09:19 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[CreateTempTableForPostIdWithIdentity] 
-- Add the parameters for the stored procedure here
AS

BEGIN

-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
declare @return int


IF OBJECT_ID('PostIdWithIdentity') IS NOT NULL  
  DROP TABLE PostIdWithIdentity 
 
CREATE TABLE PostIdWithIdentity 
(
Id   int IDENTITY (1,1)     not null,
PostId nvarchar(255),
Tags nvarchar(MAX),
primary key (Id)   
)
truncate table PostIdWithIdentity 
insert into PostIdWithIdentity(PostId,Tags) select Id,Tags from [InstagramData].[dbo].[Post] 
set @return = @@identity
select @return

END

EF Code:

int? newIdentityValue = db.Database.SqlQuery<Int32>("exec CreateTempTableForPostIdWithIdentity").FirstOrDefault();

=====EXAMPLE 2，no return value

STORE PROC

USE [InstagramData]
GO
/****** Object:  StoredProcedure [dbo].[CreateTempTableForPostIdWithIdentity]    Script Date: 2014/12/5 15:09:19 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[CreateTempTableForPostIdWithIdentity] 
-- Add the parameters for the stored procedure here
AS
BEGIN

-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
declare @return int


IF OBJECT_ID('PostIdWithIdentity') IS NOT NULL  
  DROP TABLE PostIdWithIdentity 
 
CREATE TABLE PostIdWithIdentity 
(
Id   int IDENTITY (1,1)     not null,
PostId nvarchar(255),
Tags nvarchar(MAX),
primary key (Id)   
)
truncate table PostIdWithIdentity 
insert into PostIdWithIdentity(PostId,Tags) select Id,Tags from [InstagramData].[dbo].[Post] 
END

EF CODE:

db.Database.ExecuteSqlCommand("exec CreateTempTableForPostIdWithIdentity");

EXAMPLE 3 ，带参数的

Store Proc

USE [InstagramData]
GO
/****** Object:  StoredProcedure [dbo].[GetDataFromPostIdWithIdentity]    Script Date: 2014/12/5 15:09:23 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO


ALTER PROCEDURE [dbo].[GetDataFromPostIdWithIdentity]
-- Add the parameters for the stored procedure here
@StartWith int,
@Count int


AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;


Select Id,PostId,Tags from PostIdWithIdentity order by ID OffSET @StartWith ROW FETCH NEXT @Count ROWS only
--Select * from PostIdWithIdentity order by ID OffSET 10 ROW FETCH NEXT 10 ROWS only
-- Insert statements for procedure here
--SELECT row_number() over (order by Id asc) as id,Id as PostId,Tags From  [InstagramData].[dbo].[Post] 
END

EF Code

var data = db.Database.SqlQuery <DataFromPostIdWithIdentity>("exec GetDataFromPostIdWithIdentity @StartWith,@Count", new SqlParameter("StartWith", startWith), new SqlParameter("Count", _getRowCount)).ToList(); 

public class DataFromPostIdWithIdentity
    {
        public int Id { set; get; }


        public string PostId { get; set; }


        public string Tags { get; set; }
    }
