Asp.net mvc 如何在ASP.NET MVC中使用实体框架、存储库模式和在给定sp上创建基于角色的访问来使用存储过程

如何使用实体框架、存储库模式在ASP.NET MVC中使用存储过程，并在给定sp上创建角色库访问。我必须使用下面的sp创建角色库访问。我是新手，我不知道如何创建和使用此存储过程。谢谢

  CREATE PROCEDURE [dbo].[sp_AccountAccess] 
    @UserName NVARCHAR(255), @Password NVARCHAR(255)

    AS

    SELECT CASE WHEN (
SELECT UserType
    FROM (SELECT Username, Password, 'Admin' UserType 
            FROM AccountAccess AC
            WHERE EXISTS (SELECT * FROM v_Admins AD WHERE AD.Email = AC.Email)
            UNION ALL

            --Sales by Department
            SELECT Username, Password, 'Department' UserType
            FROM AccountAccess AC
            WHERE SalesView <> ''
            AND  AC.Department <> SalesView
            AND NOT EXISTS (SELECT * FROM v_AllUser AD WHERE AD.Email = AC.Email)
            AND Email NOT LIKE '%process%'
            AND Email <> ''
            AND Password <> ''
            UNION ALL

    (SELECT UserType
    SELECT UserType

            WHERE SalesView <> ''
            AND  AC.Department <> SalesView

您是否先使用数据库？还是类优先？我们使用的实体框架代码优先和存储库模式。
