Question

我有这个存储过程：

USE [Events2]
GO
/****** Object:  StoredProcedure [dbo].[spUpdateRegistrantPaper]    Script Date: 11/20/2015 7:02:31 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[spUpdateRegistrantPaper]
    -- Add the parameters for the stored procedure here
        @RegistrantId int,
        @LocalNumber int,
        @LocalUnionEmail nvarchar(50),
        @DistrictId int,
        @CompletedByFirstName nvarchar(20),
        @CompletedByLastName nvarchar(25),
        @CompletedByPhone nvarchar(15),
        @FirstName nvarchar(20),
        @LastName nvarchar(25),
        @Position nvarchar(15),
        @Email nvarchar(50),
        @ShirtSize nvarchar(50),
        @Comments nvarchar(300)
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    UPDATE Registrant SET
        LocalNumberId = @LocalNumber,
        LocalUnionEmail = @LocalUnionEmail,
        DistrictId = @DistrictId,
        CompletedByFirstName = @CompletedByFirstName,
        CompletedByLastName = @CompletedByLastName,
        CompletedByPhone = @CompletedByPhone,
        FirstName = @FirstName,
        LastName = @LastName,
        Position = @Position,
        Email = @Email,
        ShirtSize = @ShirtSize,
        Comments = @Comments
        WHERE RegistrantId = @RegistrantId
END

我有一个带有编辑和更新按钮的GridView。

  <UpdateParameters>
                <asp:Parameter Name="RegistrantId" Type="Int32" />
                <asp:Parameter Name="LocalNumber" Type="Int32" />
                <asp:Parameter Name="LocalUnionEmail" Type="String" />
                <asp:Parameter Name="DistrictId" Type="Int32" />
                <asp:Parameter Name="CompletedByFirstName" Type="String" />
                <asp:Parameter Name="CompletedByLastName" Type="String" />
                <asp:Parameter Name="CompletedByPhone" Type="String" />
                <asp:Parameter Name="FirstName" Type="String" />
                <asp:Parameter Name="LastName" Type="String" />
                <asp:Parameter Name="Position" Type="String" />
                <asp:Parameter Name="Email" Type="String" />
                <asp:Parameter Name="ShirtSize" Type="String" />
                <asp:Parameter Name="Comments" Type="String" />
            </UpdateParameters>

但是我收到了这个错误：

过程或函数spUpdateRegistrantPaper包含太多参数指定。

我不明白为什么...... ???我该怎么做才能解决这个问题？

请注意，您在GridView中使用了大量BoundField个。要了解这些字段的事情是它们的值会自动添加到update / insert命令中。例如：

<asp:BoundField DataField="LocalNumberId" HeaderText="Local" 
    SortExpression="LocalNumberId" />

这将导致param LocalNumberId被添加到存储过程的调用中。由于您已经只有LocalNumber作为参数，因此LocalNumberId出乎意料。因此，您拥有在UpdateParameters标记中明确声明的所有参数以及BoundField中的其他参数。

我在这里看到你的选择：

确保BoundFields在存储的proc中准确表示您想要的参数，根据需要重命名列或存储的proc参数。

删除绑定字段，使用TemplateFields代替Eval。简单的例子：

而不是

<asp:BoundField DataField="LocalNumberId" HeaderText="Local" 
            SortExpression="LocalNumberId" />

你会有

<asp:TemplateField HeaderText="Local" SortExpression="LocalNumberId">
    <ItemTemplate>
        <%# Eval("LocalNumberId") %>
    </ItemTemplate>
</asp:TemplateField>

仅使用您需要的参数，以UpdateCommand手动编写对存储过程的调用

GridView - 过程或函数指定了太多参数
