Question

Select productid,
       (
           Select name
           From   menu
           Where  id = productid
       ) As Foodname,
       price,
       quantity,
       price * quantity As total
From   salesdetail
Where  salesid = (
                     Select id
                     From   booking
                     Where  secret = 'ypnok3bd'
                            And id = 'SSD00000000000000001'
                 );

DataBinding：＆＃39; System.Data.DataRowView＆＃39;不包含名称为＆＃39; productID＆＃39;的属性。我检查过这些字段是否正确，但为什么它仍然不能？

 <table border="1">
        <tr>
            <td>Food ID</td>
            <td>Food Name</td>
            <td>Quantity</td>
            <td>Price</td>
            <td>Total</td>

        </tr>

        <asp:ListView ID="listView1" runat="server">

            <ItemTemplate>

                <tr>
                    <td><%# Eval("productID") %></td>
                    <td><%# Eval("Foodname") %></td>
                    <td><%# Eval("quantity") %></td>
                    <td><%# Eval("price") %></td>
                    <td><%# Eval("total") %></td>
                </tr>
            </ItemTemplate>
        </asp:ListView>

    </table>
