问题在asp.net mvc的SP

Question

我有asp.net的MVC 4项目中，尝试调用T-SQL，我需要选择一些行与并非所有列

CREATE PROCEDURE [dbo].[SP_name] 
@iSkip int, @iTake int 
    AS 
    BEGIN 
    SELECT [Column1], [Column2], [Column3] FROM [dbo].[Table] WITH(NOLOCK) 
    ORDER BY 
    [Column1] DESC 
OFFSET @iSkip ROWS 
FETCH NEXT @iTake ROWS ONLY 
    END 

但是，当我尝试调用该SP从代码中我有以下错误

The data reader is incompatible with the specified 'Model.Table'. A member of the type, 'Column4', does not have a corresponding column in the data reader with the same name. 

当我试图把这种对MS SQL工作室一切正常，没有任何人知道哪里是我的错？我该怎么做？

编辑：

这是库：

public IEnumerable<T> GetAllEntitiesWithParam(string procedureName, int param1, int param2) { 
      return _context.DbContext.Database.SqlQuery<T>("EXEC " + procedureName + " @param1, @param2", new SqlParameter("param1", param1), new SqlParameter("param2", param2)); 
     } 

这里是内部代码：

IEnumerable<Table> list = _myRepo.GetAllEntitiesWithParam("SP_name", par1, par2);

的错误似乎很清楚 - 你有你的模型Column4那不在该sproc的结果集中。您可以为存储过程添加“默认”值：

CREATE PROCEDURE [dbo].[SP_name] 
@iSkip int, @iTake int 
    AS 
    BEGIN 
    SELECT [Column1], 
      [Column2], 
      [Column3], 
      NULL AS [Column4]  // <---------------- 
    FROM [dbo].[Table] WITH(NOLOCK) 
    ORDER BY 
    [Column1] DESC 
OFFSET @iSkip ROWS 
FETCH NEXT @iTake ROWS ONLY 
    END
