如何使用代码优先 ASP.NET MVC 和实体框架导入存储过程

Question

我想先使用 EF 代码导入存储过程，代码是从 SQL Server 创建的。我试图检查发布的文章，但到目前为止我似乎没有找到我理解的东西。下面的 SQL 语句是 3 个表连接，所以如果我可以使用下面的示例代码获得一个如何解决它的示例。

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[InvoiceReport]
AS
    SELECT 
        Ordering.order_id,
        Ordering.CustomerId,
        Ordering.invoice_number,
        Ordering.date_order_placed, 
        Customer.FirstName, 
        Customer.LastName, 
        Customer.EmailId, 
        Invoice_Line_Items.item, 
        Invoice_Line_Items.department, 
        Invoice_Line_Items.service, 
        Invoice_Line_Items.gender, 
        Invoice_Line_Items.quantity, 
        Invoice_Line_Items.price, 
        Invoice_Line_Items.pick_up_address, 
        Invoice_Line_Items.pick_up_date, 
        Invoice_Line_Items.pick_up_time, 
        Invoice_Line_Items.drop_off_address, 
        Invoice_Line_Items.drop_off_date, 
        Invoice_Line_Items.drop_off_time 
    FROM 
        Ordering 
    JOIN
        Customer ON Ordering.CustId = Customer.CustId
    JOIN
        Invoice_Line_Items ON Customer.CustId = Invoice_Line_Items.CustId

RETURN 0

我通常以如下方式使用存储过程：

• 添加EF代码先迁移(https://www.entityframeworktutorial.net/code-first/code-based-migration-in-code-first.aspx)
• 通过Sql()将存储过程添加到您的迁移中
• 使用模型构建器或在您的实体中配置存储过程
• 在您的代码中使用它:-)

迁移示例：

public partial class yourmigration: DbMigration
{
    protected override void Up()
    {
        Sql("CREATE PROCEDURE SQL HERE");
    }

    //dont forget the down.
}

对于 EF 6，这里有一篇关于它的好文章：https://www.entityframeworktutorial.net/entityframework6/code-first-insert-update-delete-stored-procedure-mapping.aspx
