查询返回任何记录显示在我的网页

问题描述

我有在那里我运行下面的code网站：

 ＆LT; ASP：的AccessDataSource ID =AccessDataSource1=服务器
    数据文件=〜/ App_Data文件/ TravelJoansDB.accdb
    的SelectCommand =SELECT * FROM [表2] INNER JOIN BlogEntryItems ON Table2.ID = BlogEntryItems.BlogID WHERE（[Table2.ID] = @ ID）＆GT;
    ＆LT; SelectParameters＆GT;
        ＆LT; ASP：QueryStringParameter名称=IDQueryStringField =Table2.IDTYPE =十进制/＆GT;
    ＆LT; / SelectParameters＆GT;
＆LT; / ASP：的AccessDataSource＆GT;
 

这似乎返回任何记录，虽然我已经运行在Access查询，并返回我期待的记录。注：在我的访问查询，我取代

  WHERE（[Table2.ID] = @ ID）
 

与

 ，其中Table2.ID = 4
 

解决方案

请在你的code中的查询完全一样，你正在运行对访问之一。 （替换 @ID 与 4 ）。如果它返回你所期望的记录，问题是与 @ID 。

如果它仍然显得返回任何记录，那么你的问题是，无论是与你是如何将您的命令将数据库或如何你正在阅读的结果。

I've got a website where I'm running the following code:

<asp:AccessDataSource ID="AccessDataSource1" runat="server"
    DataFile="~/App_Data/TravelJoansDB.accdb"
    SelectCommand="SELECT * FROM [Table2] INNER JOIN BlogEntryItems ON  Table2.ID=BlogEntryItems.BlogID WHERE ([Table2.ID]=@ID)">
    <SelectParameters>
        <asp:QueryStringParameter Name="ID" QueryStringField="Table2.ID" Type="Decimal" />
    </SelectParameters>
</asp:AccessDataSource>

It seems to return no records, although I have run the query in Access and it returns the records I'm expecting. Note: In my query in Access, I substituted

WHERE ([Table2.ID]=@ID)

with

WHERE Table2.ID=4

解决方案

Make the query in your code exactly the same as the one you're running against Access. (Replace @ID with 4.)If it returns the records you expect, the problem is with @ID.

If it still appears to return no records, then your problem is either with how you're sending your command to the database or how you're reading the results.
