NHibernate原生SQL查询

习惯原生SQL的同学刚搞NH可能觉得坐点复杂的查询NH就无能为力了，其实不然，NH提供了使用原生SQL的功能，就是有些地方要注意下。

原生的SQL如图，查询每天的售票情况。。下面我们来看看NH里怎么写

        public IList<object[]> GetDaysOrderTotal()
        {
            string timeUnit = "100";
            string sql = "select CONVERT(VARCHAR(" + timeUnit + "), od.BuyTime, 102) timeUnit,count(*) count " +
"from TicketAssign ta, OrderDetail detail,[Order] od ,DJ_TourEnterprise dj,TicketPrice tp,Ticket t "+
"where ta.OrderDetail_id =detail.Id and detail.Order_id=od.Id "+
"and detail.TicketPrice_id=tp.Id and tp.Ticket_id=t.Id and t.Scenic_id=dj.Id group by CONVERT(VARCHAR(" + timeUnit + "), od.BuyTime, 102)";
            var query = session.CreateSQLQuery(sql)
                .AddScalar("count",NHibernateUtil.Int32)
                .AddScalar("timeUnit",NHibernateUtil.String);
            return query.List<object[]>();
        }

同时，前台绑定object也要这样

    <asp:Repeater runat="server" ID="rptdate">
        <HeaderTemplate>
            <table>
        </HeaderTemplate>
        <ItemTemplate>
            <tr>
                <td>
                    <a href='/manager/quzhouspring/TicketStatistics3.aspx?date=<%# ((object[])Container.DataItem)[1].ToString() %>'>
                        <%# ((object[])Container.DataItem)[1].ToString() %></a>
                </td>
                <td>
                    <%# ((object[])Container.DataItem)[0].ToString() %>
                </td>
            </tr>
        </ItemTemplate>
        <FooterTemplate>
            </table>
        </FooterTemplate>
    </asp:Repeater>
