asp.net - 给我的 ASP 问题，错误：过程或函数 uspPatientUpdate 指定了太多参数

Question

发生了什么：我正在尝试使用存储过程更新 gridview 表中的患者表。

错误：

“DropDownList2”有一个无效的 SelectedValue，因为它不存在于项目列表中。参数名称：值

这是我的程序：

ALTER PROCEDURE dbo.uspPatientUpdate
    @ID int,
    @OHIP char(10),
    @FirstName nvarchar(20),
    @LastName nvarchar(40),
    @DOB date,
    @VisitsPerYear int,
    @DoctorID int
AS
BEGIN
    SET NOCOUNT OFF
    UPDATE Patient
    SET OHIP = @OHIP,
      FirstName = @FirstName, 
      LastName = @LastName,
      DOB = @DOB,
      VisitsPerYear = @VisitsPerYear,
      DoctorID = @DoctorID
    WHERE ID = @ID 
END

这是我的asp：

uspPatientUpdate缺少TimeStamp参数：

<UpdateParameters>
  ...
  <asp:Parameter Name="Timestamp" Type="Object"></asp:Parameter>
</UpdateParameters>

或者，也许它没有丢失它，您根本不应该在标记中指定它。
