Question

我正在使用实体框架，我必须使用存储过程更新表，但我收到错误

“数据阅读器与指定的型号”backupmodel.company“不兼容。属于该类型的companyid的成员，数据阅读器中没有相应的列具有相同的名称。” < / p>

如何纠正这个......请建议解决..

存储过程：

ALTER PROCEDURE [dbo].[sp_UpdateCompany]
(
     @CompanyId int
    ,@CompanyName varchar(50)
    ,@CompanyUrl varchar(50)
    ,@CompanyType varchar(50)
    ,@Country varchar(50)
    ,@State varchar(50)
    ,@ZipCode varchar(10)
    ,@Industry varchar(50)
    ,@RevenueSize int
    ,@Vertical int
    ,@Employee int
)
as
BEGIN
    set @CompanyUrl=REPLACE(@CompanyUrl,' ','') 
    UPDATE Companies 
    SET
    CompanyName=@CompanyName,
    CompanyUrl=@CompanyUrl,
    CompanyType=@CompanyType,
    Country=@Country,
    State=@State,
    ZipCode=@ZipCode,
    Industry=@Industry,
    RevenueSize=@RevenueSize,
    Vertical=@Vertical,
    EmpSize=@Employee
    where
    CompanyId=@CompanyId    
END

显示错误：

我正在调用存储过程，如：

BDE_backupEntities obj = new BDE_backupEntities();
 public ActionResult Save(string Name, string Url, string RecordOwner)
        {
            var x = obj.Companies.ToList();
            x = (from n in obj.Companies where n.CompanyUrl.Contains(Url) select n).ToList();
            int? Id=x[0].CompanyId;
            obj.sp_UpdateCompany(Id, Name, Url, "solutions", "USA", "us", "s1234", "IT", 0, 0, 0);
            return View("CompanyDetails");
        }

Answer 1

如果您正在使用EF并将存储过程与输出参数一起使用，则需要在函数导入中将返回类型标记为NONE。

数据读取器与模型不兼容。该类型的成员，数据读取器中没有相应的列具有相同的名称
