MYSQL计数与内部联接不工作

Question

我有两个表

1）外展

id profile_id url 
------------------------- 
1 2  www.test.com 
2 3  www.google.com 
3 4  www.example.com 
4 2  www.test2.com 
5 2  www.test3.com 
6 2  www.test4.com 

2）。 outreach_links

id outreach_id start_date    created_at  cost status 
----------------------------------------------------------------------- 
1 1   2016-12-01 00:00:00 2016-12-07 00:00:00 100.00 Approved 
2 1   2016-12-02 00:00:00 2016-12-09 00:00:00 120.00 Approved 
3 1   NUll     2016-12-28 00:00:00 20.00 Pending 
4 1   2016-12-05 00:00:00 2016-12-10 00:00:00 35.00 Approved 
5 1   2016-12-07 00:00:00 2016-12-13 00:00:00 10.00 Approved 
6 2   2016-12-10 00:00:00 2016-12-15 00:00:00 10.00 Pending 
7 2   2016-12-13 00:00:00 2016-12-18 00:00:00 10.00 Approved 
8 2   2016-12-01 00:00:00 2016-12-28 00:00:00 10.00 Pending 
9 2   2016-12-04 00:00:00 2016-12-21 00:00:00 10.00 Approved 
10 2   2016-12-09 00:00:00 2016-12-22 00:00:00 15.00 Pending 

我试图做的月/年计，我认为它的工作，但我认为它不工作，因为“PROFILE_ID”这里的问题是我的查询：

select monthname(date) as Month, year(date) as Year, month(date) as Mn, UNIX_TIMESTAMP(CONCAT(year(date),"-",month(date),"-","01")) as tt, 
(select count(*) from outreach_links where year(outreach_links.created_at) = year and month(outreach_links.created_at) = month and status = "Pending" and created_at>="2016-12-01 00:00:00" and created_at<="2016-12-31 00:00:00") as pp, 
(select count(*) from outreach_links where year(outreach_links.start_date) = year and month(outreach_links.start_date) = month and status = "Approved" and start_date>="2016-12-01 00:00:00" and start_date<="2016-12-31 00:00:00") as aa, 
(select sum(cost) from outreach_links where year(outreach_links.start_date) = year and month(outreach_links.start_date) = month and status = "Approved" and start_date>="2016-12-01 00:00:00" and start_date<="2016-12-31 00:00:00") as cc 
from 
(select year(outreach_links.created_at) as year, month(outreach_links.created_at) as month, outreach_links.created_at as date 
from outreach_links 
inner join outreach on outreach.id = outreach_links.outreach_id 
where outreach_links.created_at>="2016-12-01 00:00:00" and outreach_links.created_at<="2016-12-31 00:00:00" and outreach.profile_id=2 
union 
select year(outreach_links.start_date) as year, month(outreach_links.start_date) as month, outreach_links.start_date as date 
from outreach_links 
inner join outreach on outreach.id = outreach_id 
where start_date>="2016-12-01 00:00:00" and start_date<="2016-12-31 00:00:00" and outreach.profile_id=2) t1 
group by year, month 
order by date 

所以我我所做的日期范围从“2016-12-01 00:00:00”到“2016-12-31 00:00:00”，这些日期范围可以是用户输入的任何日期范围，并尝试根据outreach.profile_id = 2，我的输出是错误的，它计算所有的profile_ids的一切，我不知道为什么

注：这只是一个表的样本，可能有更多的记录和用户inputed日期范围到可能是不同的，我想他们按月/年

这里是我的输出： （其计算所有记录）

array:1 [▼ 
    0 => {#394 ▼ 
    +"Month": "December" 
    +"Year": "2016" 
    +"Mn": "12" 
    +"tt": "1480568400.000000" 
    +"pp": "4" 
    +"aa": "6" 
    +"cc": "285.00" 
    } 
] 

哪项是错误的，应该= 2，这里所需要的输出我想只为PROFILE_ID数：

array:1 [▼ 
    0 => {#394 ▼ 
    +"Month": "December" 
    +"Year": "2016" 
    +"Mn": "12" 
    +"tt": "1480568400.000000" 
    +"pp": "1" 
    +"aa": "4" 
    +"cc": "265.00" 
    } 
] 

正如你可以看到3个计数是错误的，他们假设是： “页”： “1” “AA”： “4” “CC”： “265.00”

这里就是我寻找：

1). **"pp" is Total Pending** Count when status="Pending" based on created_at 
2). **"aa" is Total Approved** Count when status="Approved" based on start_date 
3). **"cc" is Total Cost** Sum of All cost when Status="Approved" and based on start_date 
4). Group by Month & Year of the user imputed Date Range 

这里是一个SQLFIDDLE >>http://sqlfiddle.com/#!9/87dfa8/1

你能帮我解决吗？

感谢

我想你想是这样的：

SELECT MONTHNAME(d.date) AS Month 
     , YEAR(d.date)  AS Year 
     , MONTH(d.date)  AS Mn 
     , SUM(IF(l.status = 'Pending' AND l.created_at >= d.date AND l.created_at < d.date + INTERVAL 1 MONTH ,1  ,0)) AS pp 
     , SUM(IF(l.status = 'Approved' AND l.start_date >= d.date AND l.start_date < d.date + INTERVAL 1 MONTH ,1  ,0)) AS aa 
     , SUM(IF(l.status = 'Approved' AND l.start_date >= d.date AND l.start_date < d.date + INTERVAL 1 MONTH ,l.cost,0)) AS cc 
    FROM (SELECT '2016-12-01' + INTERVAL 0 MONTH AS date) d 
    JOIN outreach o 
    ON o.profile_id = 2 
    LEFT 
    JOIN outreach_links l 
    ON l.outreach_id = o.id 
    AND ( ( l.start_date >= d.date + INTERVAL 0 MONTH 
      AND l.start_date < d.date + INTERVAL 1 MONTH 
      ) 
     OR ( l.created_at >= d.date + INTERVAL 0 MONTH 
      AND l.created_at < d.date + INTERVAL 1 MONTH 
      ) 
     ) 
    GROUP BY d.date

编辑

要使用的起始日期，内嵌沿着指定范围的结束日期查看d可以返回两个日期值。并且外部查询可以引用第二个日期值，在此示例中为d.end_date，以及范围d.date的开始。

SELECT MONTHNAME(d.date) AS Month 
     , YEAR(d.date)  AS Year 
     , MONTH(d.date)  AS Mn 
     , SUM(IF(l.status = 'Pending' AND l.created_at >= d.date AND l.created_at < d.end_date,1  ,0)) AS pp 
     , SUM(IF(l.status = 'Approved' AND l.start_date >= d.date AND l.start_date < d.end_date,1  ,0)) AS aa 
     , SUM(IF(l.status = 'Approved' AND l.start_date >= d.date AND l.start_date < d.end_date,l.cost,0)) AS cc 
    FROM (SELECT '2016-12-01' + INTERVAL 0 MONTH AS date 
       , '2016-12-16' + INTERVAL 0 MONTH AS end_date 
     ) d 
    JOIN outreach o 
    ON o.profile_id = 2 
    LEFT 
    JOIN outreach_links l 
    ON l.outreach_id = o.id 
    AND ( ( l.start_date >= d.date 
      AND l.start_date < d.end_date 
      ) 
     OR ( l.created_at >= d.date 
      AND l.created_at < d.end_date 
      ) 
     ) 
    GROUP BY d.date, d.end_date
