Question

我正在使用stored-procedure更新表上的字段。我不想更新所有字段，因此不需要的字段未包含在存储过程中。

当我尝试使用以下代码从控制器调用stored-procedure时，会得到：The

数据读取器与指定的“ EMSMVCModel.Call_Info”不兼容。类型为“ ambulanceDispatch”的成员在数据读取器中没有与之相同的对应列名称。

 var insert_query = entities.Database.SqlQuery<Call_Info>("exec [dbo].[update_call_info]  @call_info_id, @call_id, @user_id, @ambulanceNum, @patientId, @patientName, @dateOfBirth, @ethnicity, @gender,
                        new SqlParameter("call_info_id", call_info_id),
                        new SqlParameter("call_id", call_id),
                        new SqlParameter("user_id", u_id),
                        new SqlParameter("ambulanceNum", ambulanceNum),
                        new SqlParameter("patientId", patientId),
                        new SqlParameter("patientName", patientName),
                        new SqlParameter("dateOfBirth", dateOfBirth),
                        new SqlParameter("ethnicity", ethnicity),
                        new SqlParameter("gender", gender)
                        )
                        .Select(x => new
                        {
                            x.call_info_id,
                            x.call_id,etUser,
                            x.Call,*/
                            StatusCode = 1 //Success StatusCode
                        }).ToList();

但是，我的表中还有更多字段，例如ambulanceDispatch。我的call_info类如下：

 public partial class Call_Info
    {
        public int call_info_id { get; set; }
        public int call_id { get; set; }
        public string user_id { get; set; }
        public int ambulanceNum { get; set; }
        public string patientId { get; set; }
        public string patientName { get; set; }
        public System.DateTime dateOfBirth { get; set; }
        public string ethnicity { get; set; }
        public Nullable<int> gender { get; set; }
        public System.DateTime ambulanceDispatch { get; set; }
        public System.DateTime arrivalOnScene { get; set; }

    }

在SQL Server中，存储过程正在运行，如下所示。

请注意，我实际的存储过程还有更多字段。

您的结果集（存储过程的输出）不包含名为

的列

ambulanceDispatch

https://docs.microsoft.com/en-us/dotnet/api/system.data.entity.database.sqlquery?view=entity-framework-6.2.0

创建一个原始SQL查询，该查询将返回给定类型的元素。该类型可以是具有与以下名称匹配的属性的任何类型查询返回的列，或者可以是简单的原语类型。该类型不必是实体类型。结果即使对象类型，查询也不会被上下文跟踪返回的是实体类型。使用SqlQuery（String，Object []）方法返回由上下文跟踪的实体。

请注意，“ 类型可以是具有与查询返回的列名称相匹配的属性的任何类型，”

名称必须匹配。

您需要创建一个POCO对象，该对象与存储过程中返回列的（所有）列名和数据类型相匹配。
