如何使用Linq To SQL從存儲過程中檢索返回值和結果集？

Question

考慮這樣一個存儲過程：

create procedure p1 as 
begin 
    declare @n1 int; 
    select @n1=count(*) 
    from Employee; 

    select top 100 * 
    from Employee; 
    return @n1; 
end 

如何使用LINQ在C＃SQL我捕捉@n1以及員工的ResultSet？

Answer 1

您需要的OUTPUT參數

create procedure p1(@n1 int =0 OUTPUT) as 
begin 
    select 
     @n1=count(*) 
    from 
     Employee 

    select top 100 
     * 
    from 
     Employee 
end 

- 兼記住，你必須表明參數是當你執行PROC

Declare @val int 
exec p1 @val OUTPUT 

Answer 2

解決輸出：

//I can access the resultset as following: 
var emps = dataContext1.p1; 

//I can get to @n1 by this: 
int i1=int(emps).ReturnValue;
