I am trying to do a count by Month/Year and I thought its working but I think its not working because of "profile_id" issue here is my query:
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
So I am doing a date range from "2016-12-01 00:00:00" to "2016-12-31 00:00:00" these could be any date range inputed by the user , and try to do a count based on outreach.profile_id = 2 , my output is wrong its counting everything for all profile_ids, I am not sure why
Note: this is just a sample of the tables , there might be more records and the user inputed Date range from to could be different , I want to group them by Month / Year
here is my output: ( its counting ALL records)
array:1 [▼
0 => {#394 ▼
+"Month": "December"
+"Year": "2016"
+"Mn": "12"
+"tt": "1480568400.000000"
+"pp": "4"
+"aa": "6"
+"cc": "285.00"
}
]
Which is wrong it should count only for profile_id=2 , here is the DESIRED output I want:
array:1 [▼
0 => {#394 ▼
+"Month": "December"
+"Year": "2016"
+"Mn": "12"
+"tt": "1480568400.000000"
+"pp": "1"
+"aa": "4"
+"cc": "265.00"
}
]
As you can see the 3 counts are wrong they suppose to be:
"pp": "1"
"aa": "4"
"cc": "265.00"
here is what I am looking for:
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
here is a SQLFIDDLE >> http://sqlfiddle.com/#!9/87dfa8/1
can you please help me fix it?
Thanks

Answer 1

I think you want something like this:
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
EDIT
To specify the end date of the range along with the start date, the inline view d can return two date values. And the outer query can reference the second date value, in this example d.end_date, as well as the start of the range d.date.
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
