Question

是否可以按LastActivityDate

的顺序显示此数据

<asp:AccessDataSource ID="usage_info_DS" runat="server" DataFile="~/App_Data/ASPNetDB.mdb" SelectCommand="SELECT aspnet_Users.UserName, aspnet_Users.LastActivityDate, aspnet_Membership.LastLoginDate FROM (aspnet_Membership INNER JOIN aspnet_Users ON aspnet_Membership.UserId = aspnet_Users.UserId) WHERE (aspnet_Membership.UserId <> 100) AND (aspnet_Membership.UserId IN (SELECT UserId FROM aspnet_UsersInRoles WHERE (RoleId = (SELECT RoleId FROM aspnet_Roles WHERE (RoleName = ?)))))">
        <SelectParameters>
            <asp:ControlParameter ControlID="DropDownList1" Name="?" PropertyName="SelectedValue" />
        </SelectParameters>
    </asp:AccessDataSource>

干杯罗斯

Answer 1

试

<asp:AccessDataSource ID="usage_info_DS" runat="server" DataFile="~/App_Data/ASPNetDB.mdb" SelectCommand="SELECT aspnet_Users.UserName, aspnet_Users.LastActivityDate, aspnet_Membership.LastLoginDate FROM (aspnet_Membership INNER JOIN aspnet_Users ON aspnet_Membership.UserId = aspnet_Users.UserId) WHERE (aspnet_Membership.UserId <> 100) AND (aspnet_Membership.UserId IN (SELECT UserId FROM aspnet_UsersInRoles WHERE (RoleId = (SELECT RoleId FROM aspnet_Roles WHERE (RoleName = ?))))) order by aspnet_Users.LastActivityDate">
        <SelectParameters>
            <asp:ControlParameter ControlID="DropDownList1" Name="?" PropertyName="SelectedValue" />
        </SelectParameters>
    </asp:AccessDataSource>

Answer 2

在sql语句中使用order by clause。所以你的查询应该是：

SELECT 
aspnet_Users.UserName, 
aspnet_Users.LastActivityDate, 
aspnet_Membership.LastLoginDate 
FROM 
        (aspnet_Membership INNER JOIN aspnet_Users ON aspnet_Membership.UserId = aspnet_Users.UserId) 
WHERE   
        (aspnet_Membership.UserId <> 100) 
        AND (aspnet_Membership.UserId IN (SELECT UserId FROM aspnet_UsersInRoles 
                                          WHERE (RoleId = (SELECT RoleId FROM aspnet_Roles WHERE (RoleName = ?)))))
order by 2;

2指定要应用order by的列，您也可以使用列名aspnet_Users.LastActivityDate

修改

如果您想在结果集的顶部获取最新日期，请使用：

order by 2 desc;

Asp - 按日期显示数据
