Question

我有一个数据源，它有一个名为更新的sp并被绑定到gridview。我想在更新它时应该使用sp和更新表。下面是我的设计代码。

 < asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4"
        DataKeyNames="Title" DataSourceID="SqlDataSource1" EnableModelValidation="True"
        ForeColor="#333333" GridLines="None" ShowFooter="True" Width="1000" AllowPaging="true"
        PageSize="10" OnRowCommand="GridView1_RowCommand">  
        < AlternatingRowStyle BackColor="White" ForeColor="#284775" />  
        < Columns>  
            < asp:TemplateField HeaerText="Title">  
                < ItemTemplate>  
                    < asp:Label ID="lblTitle" runat="server" Text='<%# Eval("Title") %>'></asp:Label>  
                < /ItemTemplate>  
            < /asp:TemplateField>  
            < asp:TemplateField HeaderText="Quote">

        SelectCommand= "SELECT [TITLE], [QUOTE], [QUOTELINK], [PUBLISHED], [PUBLISHEDDATE] FROM [DBO].[QUOTES]"
        UpdateCommand="sp_ModifyQuotes" UpdateCommandType="StoredProcedure">  
        < UpdateParameters>  
            < asp:Parameter Name="Title" Type="String" />

以下是我的SP

ALTER PROCEDURE [dbo].[sp_ModifyQuotes]
    @Title varchar(max),
    @Quote varchar(max),
    @QuoteLink varchar(max),
    @Published Bit,
    @PublishDate DateTime,
    @Modify varchar(10)

AS
BEGIN
    Declare @QuoteId int
    IF (@Modify = 'Add')
    BEGIN
        INSERT INTO dbo.QUOTES
        (
            Title,
            Quote,
            QuoteLink,
            Published,
            PublishedDate
        )
        values
        (
            @Title,
            @Quote,
            @QuoteLink,
            @Published,
            @PublishDate
        )
        SET @QuoteId = @@IDENTITY
        If @Published = 1
        BEGIN
            UPDATE dbo.Quotes SET Published = 0 WHERE Id <> @QuoteId AND Published = 1
        END
        --SELECT @QuoteId As ID
    END
    ELSE IF (@Modify = 'Update')
    BEGIN
        UPDATE dbo.Quotes SET
        Quote = @Quote,
        QuoteLink = @QuoteLink,
        Published = @Published,
        PublishedDate = @PublishDate

        WHERE Title = @Title
        --SELECT '1' As ID

    END
    ELSE IF (@Modify = 'Delete')
    BEGIN
        DELETE FROM dbo.Quotes
        WHERE Title = @Title

        --SELECT '1' As ID
    END
END

请任何人帮助我当我尝试更新时如何更新我的记录我得到一个错误说：

过程或函数sp_ModifyQuotes 指定了太多参数。

但我想我已经通过了所有适当的参数。

Answer 1

Modify参数位于SP的INSERT / VALUES部分 - 基本上它们不匹配。

使用sqldatasource中的存储过程更新记录
