count multiple in one statement - mysql

i have a table with data title and date of the data inserted.
and right now i want to do count to make the statistic out of it.
can i do multiple count in one sql statement?
like from, the column date, i want to count how many on this month, and how many in this year, until month selected. is it possible? if yes, how?
this is what i have come up, for now.
SELECT a.trigger_type_code
, c.trigger_name
, COUNT(*) AS number
FROM issue_trigger a
INNER JOIN cs_issue b
ON b.issue_id = a.issue_id
INNER JOIN ref_trigger_type c
ON c.trigger_type_code = a.trigger_type_code
WHERE MONTH(b.created_date) = '05'
AND YEAR(b.created_date) = '2011'
GROUP BY trigger_type_code,trigger_name
by this is only for one count.help.:(

You could use a case:
select sum(case when MONTH(b.created_date) = '05'
AND YEAR(b.created_date) = '2011' then 1 end) as Count_2011_05
, sum(case when YEAR(b.created_date) = '2011'
then 1 end) as Count_2011
from ... etc ...

I think you could go like this:
SELECT
a.trigger_type_code,
c.trigger_name,
COUNT(MONTH(b.created_date) < 5 OR NULL) AS before_the_month,
COUNT(MONTH(b.created_date) = 5 OR NULL) AS in_the_month
FROM issue_trigger a
INNER JOIN cs_issue b
ON b.issue_id = a.issue_id
INNER JOIN ref_trigger_type c
ON c.trigger_type_code = a.trigger_type_code
WHERE YEAR(b.created_date) = 2011
GROUP BY a.trigger_type_code, c.trigger_name

MySQL - Joining same table twice, parent sum column value getting duplicated

I'm just 3 months of experience in MySQL. Here I'm trying to generate a report based on log and part table. When trying to join the "Part" table twice, the "Log" table Quantity gets doubled. Kindly let me know where I'm doing wrong.
Log Table
Part Table
Expected Report
Query Used
SELECT
report.*,
(SUM(report.quantity)) AS totalQuantity,
normalPart.price AS normalPrice,
premiumPart.price AS premiumPrice
FROM
log AS report
LEFT JOIN
(SELECT
*
FROM
part AS normalPart
WHERE
normalPart.type = 'normal'
GROUP BY normalPart.partNumber , normalPart.genId) AS normalPart ON report.partNumber = normalPart.partNumber
AND report.genId = normalPart.genId
AND normalPart.cat = report.fromCat
LEFT JOIN
(SELECT
*
FROM
part AS premiumPart
WHERE
premiumPart.type = 'premium'
GROUP BY premiumPart.partNumber , premiumPart.genId) AS premiumPart ON report.partNumber = premiumPart.partNumber
AND report.genId = premiumPart.genId
AND premiumPart.cat = report.toCat;
Query Result
This answers the original version of the question.
Aggregate before you join:
select l.*, p.normal_price, p.premium_price
from (select genid, partnumber, sum(quantity) as quantity
from log
group by genid, partnumber
) l left join
(select partnumber, genid,
max(case when type = 'normal' then price end) as normal_price,
max(case when type = 'premium' then price end) as premium_price
from part
group by partnumber, genid
) p
on p.partnumber = l.partnumber and p.genid = l.genid

COUNT not returning expected values

Given the following relationship between my tables:
I need to show the name of films which only have two starring actors like 'Seconday'.
SELECT act.cod_film,
(SELECT COUNT(act.cod_film) FROM film, act WHERE act.starring like
'Seconday' and act.cod_film=film.cod_film) as namecounter
FROM act;
This always returns the films with the 'Seconday' actor, but the count is always same number. I need the number of 'Seconday' actors in each film.
Any help would be appreciated
This will locate films with 2 'Secondary' actors
SELECT act.cod_film
FROM act
GROUP BY act.cod_film
HAVING SUM(CASE WHEN act.starring like = 'Seconday' THEN 1 ELSE O END) = 2
which you can use in a subquery like this (or in many other possible ways)
SELECT *
FROM FILMS
WHERE cod_film IN (
SELECT act.cod_film
FROM act
GROUP BY act.cod_film
HAVING SUM(CASE WHEN act.starring like = 'Seconday' THEN 1 ELSE O END) = 2
)
or: Which you can use this way in a join
SELECT *
FROM FILMS
INNER JOIN (
SELECT act.cod_film, COUNT(*) NUM_OF
FROM act
GROUP BY act.cod_film
HAVING SUM(CASE WHEN act.starring like = 'Seconday' THEN 1 ELSE O END) = 2
) A ON FILMS.cod_film = A.cod_film
Notes:
like requires the use of a wildcard to be effective, don't substitute equals with like they are not the same things
you can adjust the = to >= as in sum(case...) >= 2 if you wanted a minimum of 2 secondary actors
The act table is mentioned 2 times, try remove the act from the select count()
Preposition 1
SELECT act.cod_film,
(SELECT COUNT(act.cod_film) FROM film WHERE act.starring like
'Seconday' and act.cod_film=film.cod_film) as namecounter
FROM act;
Preposition 2
SELECT act.cod_film, count(*)
FROM act JOIN film ON (act.act.cod_film = film.cod_film)
WHERE act.starring like 'Seconday'
GROUP BY act.cod_film

MySQL query returning only one row because of SUM function in it

I am trying to create an advertisement query where I want to fetch data of all the impressions per advertisement. One user can have multiple advertisements and impressions will be counted in a table on per day basis. So for each day I will have one different row. Here is how my query currently looks like.
SELECT
eac.id,
eac.gender,
eac.start_date,
eac.end_date,
eac.ad_image_path,
eac.ad_link,
eac.requestfrom,
eac.traffic,
eac.registertype,
eacr.region_id,
eac.active,
eac.impression,
eac.center_image_path,
eac.bottom_image_path,
eac.approved_by,
er.name as country_name,
eac.budget,
sum(budget/ (DATEDIFF(end_date,start_date)) *1000) as daily_imp,
eaa.impression_count,
eac.customer_id,
eaa.created_at
FROM
`enrich_advert_customer` eac
JOIN `enrich_advert_customer_regions` eacr ON eac.id = eacr.advert_customer_id
JOIN `enrich_regions` er ON er.id = eacr.region_id
LEFT JOIN `enrich_advert_abstract` eaa on eac.id = eaa.advert_customer_id
WHERE
eac.requestfrom ='web' AND
eac.registertype = 'paid' AND
eac.active = 1 AND
eac.approved_by = 1 AND
eac.gender ='male' AND
er.name = 'india' AND
eac.start_date <= '2018-11-5' AND
eac.end_date >= '2018-11-10'
But the problem here is if I am using
sum(budget/ (DATEDIFF(end_date,start_date)) *1000) as daily_imp
this then its returning only one row at a time.
If you can suggest where I am making a mistake that will be helpful.
Thank you!
You need to add group by clause and others column in there as you applyied aggregation

MySQL | Sum Column If Different ID

I'm trying to Sum column only if id is different.
I tried like this, but it is not working:
SUM(CASE WHEN
DISTINCT empLeaves.ApprovedLeaveID
THEN empLeaves.TotalLeavesTaken END) AS Total
What Would be the proper way to SUM it?
Here is the total query, I am working on:
SELECT
E.employee_id AS EmployeeID,
E.employee_code AS EmployeeCode,
E.full_name AS EmployeeName,
empLeaves.LeavesFromDate,
empLeaves.LeavesToDate,
-- COUNT(empLeaves.ApprovedLeaveID) AS TotalApprovedApplications,
ATT.`in_date` AS InDate,
ATT.`out_date` AS OutDate,
SUM(CASE WHEN DISTINCT empLeaves.ApprovedLeaveID THEN empLeaves.TotalLeavesTaken END) AS Total
FROM employee E
LEFT JOIN `attendence` ATT ON ATT.`employee_id` = E.`employee_id`
LEFT JOIN (
SELECT
LA.`leave_approval_id` AS ApprovedLeaveID,
E.`employee_id` AS EmployeeID,
LA.`approved_from` AS LeavesFromDate,
LA.`approved_to` AS LeavesToDate,
DATEDIFF(LA.approved_to,approved_from) AS TotalLeavesTaken
FROM leave_application APP
INNER JOIN leave_approval LA
ON LA.`leave_application_id` = APP.`application_id` AND LA.`trashed` = 0 AND LA.`status` = 2
INNER JOIN employee E
ON E.`employee_id` = APP.`employee_id` AND E.`trashed` = 0 AND E.`enrolled` = 1
INNER JOIN ml_leave_type MLLT
ON MLLT.`ml_leave_type_id` = APP.`ml_leave_type_id` AND MLLT.`trashed` = 0
) empLeaves ON E.`employee_id` = empLeaves.EmployeeID
WHERE
E.`enrolled` = 1 AND E.`trashed` = 0
GROUP BY
E.`employee_id`,empLeaves.EmployeeID
When which ID is different from what?
In general, when you have a value in a field and you want to add them together except for those in a particular set of rows, you simply set the unwanted values to 0:
sum( case otherfield when somevalue then row.field else 0 end ) as SumOfValues
So when otherfield shows that this is the row you want included in the total, you expose the field you want to add (row.field in this example). Otherwise, you expose a zero. Of course, if the value you're testing is to find the rows you don't want in the total, just put the zero after the then and the field after the else.
