Question

我在GridView上有以下SqlDataSource。所有工作除删除功能外。

我做错了什么，没有给出错误但也没有结果。

如何解决这个问题？

 <asp:SqlDataSource ID="BookingsSQL" runat="server" ConnectionString="<%$    ConnectionStrings:BookingsConnectionString %>"
 OldValuesParameterFormatString="original_{0}" ConflictDetection="OverwriteChanges"
 SelectCommand="SELECT [ID], [programme name] AS programme_name, [Start], [Finish], [Source], [Destination], [Comment] FROM [Bookings]"
 DeleteCommand="DELETE FROM [Bookings] WHERE [programme name] = @ID" InsertCommand="INSERT INTO [Bookings] ([programme name], [Start], [Finish], [Source], [Destination], [Comment]) VALUES (@programme_name, @Start, @Finish, @Source, @Destination, @Comment)"
 UpdateCommand="UPDATE [Bookings] SET [programme name] = @programme_name, [Start] = @Start, [Finish] = @Finish, [Source] = @Source, [Destination] = @Destination, [Comment] = @Comment WHERE [ID] = @ID">
 <DeleteParameters>

      <asp:Parameter Name="Start" Type="DateTime" />
      <asp:Parameter Name="Finish" Type="DateTime" />
      <asp:Parameter Name="Source" Type="String" />
      <asp:Parameter Name="Destination" Type="String" />
      <asp:Parameter Name="Comment" Type="String" />
      <asp:Parameter Name="programme_name" Type="String" />
 </UpdateParameters>

Answer 1

我想这个：

DELETE FROM [Bookings] WHERE [programme name] = @ID

应该是这样的：

DELETE FROM [Bookings] WHERE [ID] = @ID

Answer 2

您可以[programme name]从[ID]列中删除您想要删除的其他查询。

由于该列存在，您不会收到错误，也不会删除匹配项。将查询更改为：

 DELETE FROM Bookings WHERE ID=@ID

在SqlDataSource中找不到SQL变量
