执行非查询过程不起作用的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，该存储过程返回三个值(Email，Name，CompanyID)并获得一个参数(CompanyID)，但是它不起作用.

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存储过程，该存储过程返回了数据.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，并且找不到扩展方法'SqlQuery'接受类型为'DatabaseFacade'的第一个参数(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?)

推荐答案

从此链接获取帮助在Core 2.0或EntityFramework 7中，不支持ef 6的早期版本中提供的SqlQuery功能.

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

下面是在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:在要在主db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.
