Question

我是SQl的新手，我正在运行示例，我想知道是否有人可以帮助我提供一段代码。我知道我的一个问号存在语法错误，但我无法弄清楚它的位置或为什么会发生这种情况。

这是我的代码：

-

    <br />
    <asp:Label ID="Label1" runat="server" Font-Bold="True" Font-Overline="True" 
        Font-Size="X-Large" Font-Underline="True" Text="Product Information Log"></asp:Label>
    <br />
    <br />

</div>
<asp:GridView ID="GridView1" runat="server" 
    AllowSorting="True" AutoGenerateColumns="False" BackColor="White" 
    BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" 
    DataSourceID="SqlDataSource1" 
    EmptyDataText="There are no data records to display." ForeColor="Black" 
    GridLines="Vertical">
    <AlternatingRowStyle BackColor="#808080" />
    <Columns>
        <asp:CommandField ShowSelectButton="True" />

            SortExpression="ItemNumber" />
        <asp:BoundField DataField="PLUNumber" HeaderText="PLUNumber" 
            SortExpression="PLUNumber" />
        <asp:BoundField DataField="PackSize" HeaderText="PackSize" 
            SortExpression="PackSize" />
        <asp:BoundField DataField="CaseCost" HeaderText="CaseCost" 
            SortExpression="CaseCost" />
        <asp:BoundField DataField="UnitRetailCost" HeaderText="UnitRetailCost"

            <asp:CommandField ShowDeleteButton="true" />
            <asp:CommandField ShowEditButton="true" />

    </Columns>

                <asp:Parameter Name="UnitRetailCost" Type="Int32" />
            </InsertParameters>

</asp:SqlDataSource>
</form>

Answer 1

你有

[UnitRetailCost] = ?, WHERE [CICNumber] = ?

在update语句的末尾，需要删除逗号：

[UnitRetailCost] = ? WHERE [CICNumber] = ?

SqlException（0x80131904）：'？'附近的语法不正确
