我有两张桌子
1）外展

2）。 outreach_links

我正在尝试按月/年进行计数，我认为它有效，但我认为它不起作用因为“profile_id”问题在这里是我的查询：
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
所以我的日期范围从“2016-12-01 00:00:00”到“2016-12-31 00:00:00”，这些可以是用户输入的任何日期范围，并尝试根据outreach.profile_id = 2进行计数，我的输出是错误的，它计算所有profile_ids的所有内容，我不知道为什么
注意：这只是表格的一个示例，可能会有更多记录，用户输入的日期范围可能会有所不同，我想按月/年分组
这是我的输出:(它计算所有记录）
array:1 [▼
0 => {#394 ▼
+"Month": "December"
+"Year": "2016"
+"Mn": "12"
+"tt": "1480568400.000000"
+"pp": "4"
+"aa": "6"
+"cc": "285.00"
}
]
哪个错误应该只计算profile_id = 2， 这里是我想要的渴望输出：
array:1 [▼
0 => {#394 ▼
+"Month": "December"
+"Year": "2016"
+"Mn": "12"
+"tt": "1480568400.000000"
+"pp": "1"
+"aa": "4"
+"cc": "265.00"
}
]
正如你所看到的，他们认为3个计数是错误的： “pp”：“1” “aa”：“4” “cc”：“265.00”
这就是我要找的东西：
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
这是一个SQLFIDDLE＆gt;＆gt; http://sqlfiddle.com/#!9/87dfa8/1
你可以帮我解决一下吗？由于
答案 0 :(得分：-1)
我想你想要这样的东西：
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
修改
要指定范围的结束日期以及开始日期，内联视图d可以返回两个日期值。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的开头。
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
