执行非查询程序不起作用 asp.net 核心 [英] Execute non-query procedure not working asp.net core

问题描述

我想执行一个存储过程，它返回三个值(Email、Name、CompanyID)并获取一个参数(CompanyID)，但它不起作用.

I want to execute a stored procedure which returns three values (Email, Name, CompanyID) and get one parameter (CompanyID) but it's not working.

我创建了一个具有这些属性的类和一个返回数据的存储过程.通过它显示 DatabaseFacade 错误.

I have created a class with these properties and a stored procedure which returns the data. By it is showing DatabaseFacade error.

我的代码是:

 List<MyClass> AppUser = new List<MyClass>(); //Class with three properties
 SqlParameter param1 = new SqlParameter("@CompanyID", CompanyID);
 AppUser = _context.Database.SqlQuery<CC>("GetUserAndRolesForCompany", param1).ToList(); 

显示此错误:我已包含 System.Linq

Showing this error: I have include System.Linq

DatabaseFacade"不包含SqlQuery"的定义，并且找不到接受DatabaseFacade"类型的第一个参数的扩展方法SqlQuery"(您是否缺少 using 指令或程序集引用?)

'DatabaseFacade' does not contain a definition for 'SqlQuery' and no extension method 'SqlQuery' accepting a first argument of type 'DatabaseFacade' could be found (are you missing a using directive or an assembly reference?)

Core 2.0 或 EntityFramework 7 不支持 ef 6 之前版本中提供的 SqlQuery 功能.

In Core 2.0 or EntityFramework 7 does not support SqlQuery feature which was available in previous version of ef 6.

以下是如何在 EntityFramework 7 中执行 sp 的示例.

Below is the example how you can execute sp in EntityFramework 7.

 public List<UserDetails> GetUserDetailsUsingSP(int LoggedInID)
        {
            var loggedInUser = new SqlParameter("Id", LoggedInID);

            return WidServices
                .FromSql("EXECUTE WID_Services_GetAll  @Id ", loggedInUser)
                .FirstOrDefault();
        }

注意:在主数据库上下文类下添加 DbSet 的位置添加此方法，然后通过实例化 dbContext 调用此方法.

Note : Add this method where you are adding your DbSet under your main db context class and then call this method by instantiating your dbContext.
