我有一个场景，在上传文件之前，我想检查日期和区域是否相同然后它应该提示一条javascript消息
＆＃34;具有相同日期和地区的文件已经是他们的，您要覆盖它吗？＆＃34;
如果用户单击“是”，则旧文件数据应进入历史记录表，新上传的文件应进入主表。
我的表名如下： -
WMS_Future_Del_Order_Hdr ---主表
WMS_Future_Del_Order_trl ---主表
历史表
WMS_Future_Del_Order_Hdr_h - 历史记录表
WMS_Future_Del_Order_trl_h - 历史记录表
这是我的HTML： -
<td valign="middle" width="20%">
<input id="TxtEdate" runat="server" maxlength="20" style="width: 65%; background-repeat: no-repeat;
background-position: bottom right; border: solid 1px #ACACAC" type="text" />
<cc3:Calendar ID="CalEntryDt" runat="server" DatePickerMode="true" TextBoxId="TxtEdate"
DatePickerImagePath="../Images/icon2.gif" CultureName="en-GB">
</cc3:Calendar>
</td>
<td align="left" width="10%">
<span class="xy8">Region :</span>
</td>
<td valign="left" width="40%">
<asp:DropDownList ID="ddlRegion" runat="server" Style="width: 50%; background-repeat: no-repeat;
background-position: bottom right; border: solid 1px #ACACAC; font-family: Tahoma,Arial,Helvetica,Geneva,sans-serif">
</asp:DropDownList>
</td>
另见我背后的代码： -

File.SaveAs(path);

答案 0 :(得分：0)
我认为你可以使用存储过程。
1）首先使用select
2）如果存在则意味着调用java脚本消息。否则将数据存储到主表
3）如果他们点击yes（javascript消息）
- 选择行并将选定的值传递给历史记录表写入insert查询和故事
- 然后在主表中使用Update查询并存储新的上传文件
