使用存储过程选择数据

Question

我使用存储过程来获取满足该条件的多条记录

CREATE PROCEDURE [dbo].[Sp_GetAttendanceBwDates]
@datefrom datetime,
@dateto datetime,
@empid int

ASBEGIN`
select AM.employee_Id,CONVERT(varchar(10),AM.date,111) from
tblAttendanceMaster AM where AM.employee_Id=@empid and
CONVERT(varchar(10),AM.date,111)<=CONVERT(varchar(10),@datefrom,111)
and CONVERT(varchar(10),AM.date,111)=CONVERT(varchar(10),@dateto,111)
END

在后面的代码中，执行以下代码时出现错误。我不明白

var objattendance = context.Sp_GetAttendanceBwDates(datefrom,dateto,emp);

错误信息

occurred in System.Data.Entity.dll but was not handled in user code.
   Additional information: The data reader is incompatible with the specified 'FlairModel.Sp_GetAttendanceBwDates_Result'. A member of the type, 'record_Id', does not have a corresponding column in the data reader with the same name.

我猜列中有问题，即当您在整个框架中导入 SP 时创建了属性，

所以这里的 select 语句可能存在问题，它没有返回与生成的复杂类型或生成的类型匹配的正确名称

例如，此查询具有匹配的列，例如

select AM.employee_Id as record_Id''need to be matching property name,
CONVERT(varchar(10),AM.date,111) as date''need to be matching property name
from
tblAttendanceMaster AM where AM.employee_Id=@empid and
CONVERT(varchar(10),AM.date,111)<=CONVERT(varchar(10),@datefrom,111)
and CONVERT(varchar(10),AM.date,111)=CONVERT(varchar(10),@dateto,111)
