Question

我在asp.net项目中使用UPDATE命令时遇到问题。该项目允许用户通过登录页面登录，该登录页面将用户名和密码与数据库中的记录相匹配，并将用户名保存为cookie。然后我有一个设置页面，我想让用户编辑他们的帐户详细信息，但是当我使用UPDATE函数时，执行查询没有任何错误，但不会发生更新。我正在使用AccessDataSource和UpdateCommand，希望有人可以找到我的代码的问题，并指导我正确的方向。提前致谢

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)


    Dim sqlcmd As String
    sqlcmd = "SELECT FirstName, SecondName, UserName, DOB, Password FROM UserTable WHERE UserName = '" & Request.Cookies("UserInfo")("userName") & "'"
    AccessDataSource1.SelectCommand = sqlcmd

    If (Not Page.IsPostBack) Then

        Dim sqlcmd2 As String
        sqlcmd2 = "UPDATE [UserTable] SET [FirstName] = ?, [SecondName] = ?, [UserName] = ?, [DOB] = ?, [Password] = ? WHERE [UserID] = ? AND ISNULL (([FirstName] = ?) OR ([FirstName] IS NULL AND ? IS NULL)) AND (([SecondName] = ?) OR ([SecondName] IS NULL AND ? IS NULL)) AND (([UserName] = ?) OR ([UserName] IS NULL AND ? IS NULL)) AND (([DOB] = ?) OR ([DOB] IS NULL AND ? IS NULL)) AND (([Password] = ?) OR ([Password] IS NULL AND ? IS NULL))"
        AccessDataSource1.UpdateCommand = sqlcmd2

    End If

End Sub

<form id="webform" runat="server">
    <div id="content">
     <asp:AccessDataSource ID="AccessDataSource1" DataSourceMode = "DataSet" runat="server"

            OldValuesParameterFormatString="original_{0}"  
            UpdateCommand = "UPDATE [UserTable] SET [FirstName] = ?, [SecondName] = ?, [UserName] = ?, [DOB] = ?, [Password] = ? WHERE [UserID] = ? AND ISNULL (([FirstName] = ?) OR ([FirstName] IS NULL AND ? IS NULL)) AND (([SecondName] = ?) OR ([SecondName] IS NULL AND ? IS NULL)) AND (([UserName] = ?) OR ([UserName] IS NULL AND ? IS NULL)) AND (([DOB] = ?) OR ([DOB] IS NULL AND ? IS NULL)) AND (([Password] = ?) OR ([Password] IS NULL AND ? IS NULL))">

         <UpdateParameters>
             <asp:Parameter Name="UserID" Type="Int32" />
             <asp:Parameter Name="FirstName" Type="String" />

             <asp:Parameter Name="original_Password" Type="String" />
             <asp:Parameter Name="original_Password" Type="String" />
         </UpdateParameters>
        </asp:AccessDataSource>
        <asp:GridView ID="GridView1" runat="server" DataSourceID="AccessDataSource1">
            <Columns>
                <asp:CommandField ShowEditButton="True" />
            </Columns>
        </asp:GridView>
<div>
</div>
</div>
</form>

对不起，如果它有点乱，但这是我的第一篇文章，我不完全确定我在做什么。

Answer 1

尝试添加

accessdatasource1.update()

与AccessDataSource vb asp.net一起使用时更新不起作用
