如何从多个表中的存储过程中检索数据？

I have a stored procedure in SQL as below:

我在SQL中有一个存储过程,如下所示:

CREATE PROCEDURE USP_Select
    (@id INT)
AS
    SELECT * FROM EMO;
    SELECT * FROM student WHERE id = @id;
    SELECT * FROM tbl1;

    RETURN 0

I am getting data using Entity Framework from that stored procedure using this code:

我使用以下代码从该存储过程使用Entity Framework获取数据:

Modalities context = new Modalities();
context.USP_Select(1);

How can I define which table data gets in my code?

如何定义代码中的表数据?

So here how can I get data different tables in code from the stored procedure?

那么在这里如何从存储过程中获取代码中的数据不同的表?

#1

first, add your stored procedure in .edmx file and create a complex type for that stored procedure and you can use an entity. Use the following link to create complex type

首先,在.edmx文件中添加存储过程并为该存储过程创建复杂类型,然后可以使用实体。使用以下链接创建复杂类型

Cant you just pass a parameter to select which table you wanna get data from?

你只是传递一个参数来选择你想从哪个表中获取数据?

CREATE PROCEDURE USP_Select
   @table varchar(50),
   @id INT = NULL
    AS
    BEGIN

     IF @table = "EMO" 
     BEGIN 
        SELECT * FROM EMO;
     END
     ELSE IF @table = "student"
     BEGIN
        SELECT * FROM student WHERE id = @id;
     END
     ELSE IF @table = "tal1"
     BEGIN
        SELECT * FROM tbl1;
     END


END
