在我的页面中,我有一个名为Recent activity的选项卡,其中我必须显示两种不同类型的操作
je_addchoice的表格结构
je_addpoll table
poll_id | user_id | poll_name | category_id | start_date | end_date
1 | 20 |Naturalflrs| 18 | 2012-12-03 | 2095-12-25
je_addchoice表
choice_id | poll_id | choice_creator_id | choice_name | choice_image | description | ctime
1 | 1 | 20 | Greenish | forest.jpg | forest |135453
je_user_vote table
vote_id | user_id | poll_id | choice_id | datetime_voted | user_type
12 | 31 | 1 | 1 |12-12-2606:23:17| normal
我已经显示结果页面,如下所示
使用查询
显示上述结果$result=mysql_query("SELECT * FROM je_addchoice, je_addpoll where je_addpoll.start_date <= '$check_date' AND je_addpoll.end_date >='$check_date' AND je_addpoll.poll_id=je_addchoice.poll_id order by je_addchoice.choicecreationtime desc");
两个表
1)je_addpoll(民意调查主表)
2)je_addchoice(为民意调查添加选项)
但我想在这里做的是如果任何用户投票支持民意调查,它将存储到
je_user_vote表如上图所示。
我想在同一个标签中显示最近投票的选项
答案 0 :(得分:1)
试试这个
在desc
datetime_voted
使用je_addchoice.choicecreationtime desc
订单
像这样。
$result=mysql_query("SELECT * FROM (SELECT P.poll_id,P.user_id,P.poll_name,P.category_id,P.start_date,P.end_date,C.choice_id,C.choice_creator_id,C.choice_name,C.choice_image,C.description,C.ctime FROM je_addchoice C, je_addpoll P where P.start_date <= '$check_date' AND P.end_date >='$check_date' AND P.poll_id=C.poll_id order by C.choicecreationtime desc) N,je_user_vote U WHERE U.poll_id=N.poll_id order by U.datetime_voted desc,N.choicecreationtime desc");
OR
$result=mysql_query("SELECT N.poll_id,N.user_id,N.poll_name,N.category_id,N.start_date,N.end_date,N.choice_id,N.choice_creator_id,N.choice_name,N.choice_image,N.description,N.ctime FROM (SELECT P.poll_id,P.user_id,P.poll_name,P.category_id,P.start_date,P.end_date,C.choice_id,C.choice_creator_id,C.choice_name,C.choice_image,C.description,C.ctime FROM je_addchoice C, je_addpoll P where P.start_date <= '$check_date' AND P.end_date >='$check_date' AND P.poll_id=C.poll_id order by C.choicecreationtime desc) N,je_user_vote U WHERE U.poll_id=N.poll_id order by U.datetime_voted desc,N.choicecreationtime desc");
