[英]mysql report join tables and Database structure issue
I'm trying to achieve the following report result: 我正在尝试实现以下报告结果:
campaign_name visits leads registrations
3333 3 0 0
direct 3 2 1
(null) 0 1 1
test 0 1 1
I have this database structure and I'm quite sure now that the relationships are incorrect. 我有这个数据库结构,现在我很确定关系是不正确的。 I played around with joining them but I am doing it wrong by http://sqlfiddle.com/#!9/451de/7
我和他们一起玩耍,但http://sqlfiddle.com/#!9/451de/7做错了
Your advise would be appreciated. 您的建议将不胜感激。
Try this 尝试这个
mysql_query("select campaign_name , count(t.id)
as visits, count(l.id) as leads ,count(r.id) as registrations
from trackings t
left join leads as l
on l.tracking_id =t.id
left join registrations as r
on r.tracking_id =t.id
where t.created_at between '2015-04-01' AND '2015-05-31' and t.aff_id =5
group by campaign_name");
Try This. 尝试这个。
SELECT `campaign_name`,
count(t.id) as visits,
count(l.id) as leads ,
count(r.id) as registrations
FROM `trackings` t
LEFT JOIN leads l ON t.`id` = l.`tracking_id`
LEFT JOIN registrations r ON t.`id` = r.`tracking_id`
WHERE t.created_at between '2015-04-01'
AND '2015-05-31'
AND t.aff_id =5
GROUP BY `campaign_name`
ORDER BY visits DESC
not what you are looking for because of date issue. 不是因为日期问题而在寻找什么。 trackings table id
跟踪表ID
