Include Subquery into SQL CASE Statement - mysql

Below query is used to get the number of Blocked test cases from ALM. Is it possible to include this query inside a CASE statement such that the output of the CASE Statement is "COUNT(LINK.LN_ENTITY_ID)"?
SELECT BUG.BG_BUG_ID, COUNT(LINK.LN_ENTITY_ID) AS COUNT_TC, TESTCYCL.TC_STATUS FROM BUG
LEFT JOIN ALL_LISTS
ON BG_SUBJECT = AL_ITEM_ID
INNER JOIN LINK
ON BG_BUG_ID = LN_BUG_ID
LEFT JOIN TESTCYCL
ON TESTCYCL.TC_TEST_ID = LINK.LN_ENTITY_ID AND LINK.LN_ENTITY_TYPE = 'TESTCYCL'
WHERE TESTCYCL.TC_STATUS = 'Blocked'
GROUP BY BG_BUG_ID, TESTCYCL.TC_STATUS

SELECT BUG.BG_BUG_ID,
SUM(CASE TESTCYCL.TC_STATUS WHEN ="Blocked" THEN 1 ELSE 0 END) AS COUNT_TC,
TESTCYCL.TC_STATUS
FROM BUG
LEFT JOIN ALL_LISTS
ON BG_SUBJECT = AL_ITEM_ID
INNER JOIN LINK
ON BG_BUG_ID = LN_BUG_ID
LEFT JOIN TESTCYCL
ON TESTCYCL.TC_TEST_ID = LINK.LN_ENTITY_ID AND LINK.LN_ENTITY_TYPE = 'TESTCYCL'
GROUP BY BG_BUG_ID
This query will display the total no. of bug with status="blocked" for each BUG_ID.(Assuming that you need).
Hope this helps

SQL Query based on multiple where conditions

I've got a script where checked in employee's can see the stock inventory from each other, linked with their personal stock location, so each checked in employee can see which items are in stock at different locations. However, I want the main stock (id of 1, which is not attached to an employee) to be showed always, but I can't get the query right because one of the where statements is clearly not correct:
`stock_locations`.`location_id` = 1 AND
`workschedule`.`checkedIn` = 1 AND
Rememeber, the main stock is not linked to an employee, so it doesn't show up at the workschedule table. If I remove the first statement, It clearly shows up all the checked in employee's with their location, but that doesn't give me the main stock. If I remove the second statement, it only shows me the main stock.
How can I solve this issue within SQL? This is btw the full statement:
SELECT
`item_quantities`.`item_id`,
`stock_locations`.`location_name`,
`item_quantities`.`quantity`,
`people`.`first_name`
FROM
`item_quantities`
JOIN `stock_locations` ON `item_quantities`.`location_id` = `stock_locations`.`location_id`
JOIN `items` ON `item_quantities`.`item_id` = `items`.`item_id`
LEFT JOIN `workschedule` ON `workschedule`.`linked_storage` = `stock_locations`.`location_id`
LEFT JOIN `people` ON `workschedule`.`employee_id` = `people`.`person_id`
WHERE
`stock_locations`.`location_id` = 1 AND
`workschedule`.`checkedIn` = 0 AND
`items`.`unit_price` != 0 AND
`items`.`deleted` = 0 AND
`stock_locations`.`deleted` = 0 NULL
Thanks in advance!
Make it an OR statement inside of parens.
(`stock_locations`.`location_id` = 1 OR `workschedule`.`checkedIn` = 1) AND
This will return all records that match either the main stock or the employee.
You need to use the OR operator. Clearly both things can't happen at the same time, so you need to specify each set of acceptable conditions.
SELECT
`item_quantities`.`item_id`,
`stock_locations`.`location_name`,
`item_quantities`.`quantity`,
`people`.`first_name`
FROM
`item_quantities`
JOIN `stock_locations`
ON `item_quantities`.`location_id` = `stock_locations`.`location_id`
JOIN `items`
ON `item_quantities`.`item_id` = `items`.`item_id`
LEFT JOIN `workschedule`
ON `workschedule`.`linked_storage` = `stock_locations`.`location_id`
LEFT JOIN `people`
ON `workschedule`.`employee_id` = `people`.`person_id`
WHERE
`stock_locations`.`location_id` = 1
OR (
AND `workschedule`.`checkedIn` = 1
AND `items`.`unit_price` != 0
AND `items`.`deleted` = 0
AND `stock_locations`.`deleted` = 0
NULL
)
You have LEFT JOIN, but your WHERE clause turns them into inner joins. Fixing that will probably fix your problem:
SELECT . . .
FROM item_quantities iq JOIN
stock_locations sl
ON iq.`location_id` = sl.`location_id` JOIN
items i
ON iq.`item_id` = i.`item_id` LEFT JOIN
workschedule ws
ON ws.`linked_storage` = sl.`location_id` AND
ws.`checkedIn` = 0 LEFT JOIN
--------^
people p
ON ws.`employee_id` = p.`person_id`
WHERE sl.`location_id` = 1 AND
i.`unit_price` != 0 AND
i.`deleted` = 0 AND
sl.`deleted` = 0

How to join a few tables without repeat?

I have a SQL query that left joins a few tables in different ways depending on a conditions.
SELECT
dh_partner.company_name,
dh_partner_abonnement.name,
dh_partner_abonnement.description,
dh_partner_abonnement.price,
dh_partner_abonnement.discount_price,
dh_studio.partner_id,
CONCAT('https://some.url/images/studio/logo/', dh_studio.logo) as logo_url,
CONCAT('https://some.url/studio/', dh_studio.alias) as page_url,
CONCAT('https://some.url/order/abonnement/', dh_studio.alias, '/', dh_partner_abonnement_studios.abonnement_id) as checkout_url
FROM dh_partner_abonnement
LEFT JOIN dh_partner on dh_partner.id = dh_partner_abonnement.partner_id
LEFT JOIN dh_studio on dh_studio.partner_id = dh_partner.id
LEFT JOIN dh_partner_abonnement_studios on dh_partner_abonnement_studios.studio_id = dh_studio.id
WHERE
dh_partner.status = 'active'
and dh_partner.id = dh_studio.partner_id
and dh_partner.city_id = '1'
and dh_partner_abonnement_studios.studio_id = dh_studio.id
and dh_studio.show_status = '1'
The challenge in the following code
CONCAT('https://some.url/ru/order/abonnement/', dh_studio.alias, '/', dh_partner_abonnement_studios.abonnement_id) as checkout_url
LEFT JOIN dh_partner_abonnement_studios on dh_partner_abonnement_studios.studio_id = dh_studio.id
and dh_partner_abonnement_studios.studio_id = dh_studio.id
It repeats to the each dh_partner_abonnement this column dh_partner_abonnement_studios.abonnement_id
I have to connect them correctly. I know that I need to use if, however having no idea how.
Just guessing from the table names:
SELECT
p.company_name,
pa.name,
pa.description,
pa.price,
pa.discount_price,
s.partner_id,
CONCAT('https://some.url/images/studio/logo/', s.logo) as logo_url,
CONCAT('https://some.url/studio/', s.alias) as page_url,
CONCAT('https://some.url/order/abonnement/', s.alias, '/', pa.abonnement_id)
as checkout_url
FROM dh_partner_abonnement pa
JOIN dh_partner_abonnement_studios pas ON pas.partner_id = pa.partner_id
AND pas.abonnement_id = pa.abonnement_id
JOIN dh_studio s ON s.id = pas.studio_id
AND s.show_status = 1
JOIN dh_partner p ON p.id = pa.partner_id
AND p.status = 'active'
AND p.city_id = 1
You haven't joined dh_partner_abonnement and dh_partner_abonnement_studios on the complete key, which should include the abonnement_id.
It also seems a studio has a partner_id to indicate that it belongs to a certain partner. However, in your query you are interested in the abbonement studios, so join the studio on the abbonement's studio_ids.

My where clause is returning the opposite of what I want

This is my query.
select sp.name, spi.sku, sum(spi.price), count(sp.name), spi.in_stock, spi.price, sp.is_published, spi.is_reorderable
from shop_product_category spc
inner join shop_product_category_xref spcx
on spc.shop_product_category_id = spcx.shop_product_category_id
inner join shop_product sp
on sp.shop_product_id = spcx.shop_product_id
inner join shop_product_item spi
on spi.shop_product_id = sp.shop_product_id
inner join shop_order_item soi
on spi.shop_product_item_id = soi.shop_product_item_id
where (spc.shop_product_category_id in (1316))
and sp.is_published = 1
group by sp.name
order by count(sp.name) desc
It returns everything just fine EXCEPT I want it to return lines where sp.is_published = 1 Hence the where clause. Yet to get the desired output, I have to change the current where clause to
sp.is_published <> 1
So the questions is this, why does <> 1 return rows with ones, and =1 return rows with zeros. Thanks
If sp.is_published = 1 is a string, you'll need to put it in ticks IE sp.is_published = '1'

sql inner join query can use value of outer query?

The below runs fine :
select Runs.runId,Runs.prodId,fail,Owner,
(cast(counts.Count as decimal(4,2))) as PercentAnalysed,Language,Platform
from Runs AS Runs Inner Join Product AS Product On Runs.prodId=Product.prodId
left join (SELECT COUNT(*) AS 'Count', Results.runId
FROM Results inner join Runs on Results.runId=Runs.runId
WHERE Analysed = 'True'
GROUP BY Results.runId ) counts on counts.runId = Runs.runId
I want PercentAnalysed value in outer query to be as below :
= [counts.Count/failCount] if failCount !=0
or
=[0] if failCount=0
How do I do this ?
Any idea anyone ?
You need to use the CASE statement to get what you want.
SELECT
Runs.runId,
Runs.prodId,
fail,
Owner,
CAST(CASE WHEN failcount <> 0 THEN counts.Count/failcount
WHEN failcount = 0 OR counts.Count IS NULL THEN 0
ELSE counts.Count END AS Decimal(4,2)) PercentAnalysed,
Language,
Platform
FROM

SQL Query producing wrong count result

I have the following SQL query
SELECT
DISTINCT
count("SiteTree_Live"."ID")
FROM
"SiteTree_Live"
LEFT JOIN "Page_Live" ON "Page_Live"."ID" = "SiteTree_Live"."ID"
LEFT JOIN "TourPage_Live" ON "TourPage_Live"."ID" = "SiteTree_Live"."ID"
LEFT JOIN "DepartureDate" ON "DepartureDate"."TourID" = "SiteTree_Live"."ID"
WHERE
("SiteTree_Live"."Locale" = 'en_AU')
AND ("SiteTree_Live"."ClassName" IN ('TourPage'))
AND ("DepartureDate"."DepartureDate" LIKE '2012-11%')
but it producing a wrong count as the query result. The total intented result this query is suppose to return should not be more than 245 but currently, its returning more than about "4569" results.
Thats is because of the JOIN on the "DepartureDate" table as the query returns the expected result when i remove the join from the "DepartureDate" table.
What modification do i need to make to my query to count the Macthes between "SiteTree_Live"."ID" and "DepartureDate"."TourID" whiles counting only the "SiteTree_Live"."ID" count excluding the Departure dates?
Any suggestions welcomed :)
THE ANSWER
SELECT
COUNT(DISTINCT SiteTree_Live.ID)
FROM
"SiteTree_Live" LEFT JOIN "Page_Live" ON "Page_Live"."ID" = "SiteTree_Live"."ID"
LEFT JOIN "TourPage_Live" ON "TourPage_Live"."ID" = "SiteTree_Live"."ID"
LEFT JOIN "DepartureDate" ON "DepartureDate"."TourID" = "SiteTree_Live"."ID"
WHERE
("SiteTree_Live"."Locale" = 'en_AU')
AND ("SiteTree_Live"."ClassName" IN ('TourPage'))
AND ("DepartureDate"."DepartureDate" LIKE '2013-03%')
Seems to give me the right result. Thanks for the tip #Michael Berkowski
Minor correction: if DepartureDate is a date-type, then the LIKE '2013-03% will force it to be coerced into a character type (this is a mysql feature) As a result, any indexes on DepartureDate will not be used, IIRC. Better use a plain range-query:
SELECT
COUNT(DISTINCT stl.ID)
FROM
SiteTree_Live stl
LEFT JOIN
DepartureDate dd ON dd.TourID = stl.ID
WHERE
stl.Locale = 'en_AU'
AND stl.ClassName = 'TourPage'
AND dd.DepartureDate >= '2013-03-01'
AND dd.DepartureDate < '2013-04-01'
;
Do this (You have a bunch of unneeded joins)
SELECT
COUNT(DISTINCT SiteTree_Live.ID)
FROM
`SiteTree_Live`
LEFT JOIN
`DepartureDate` ON `DepartureDate`.`TourID` = `SiteTree_Live`.`ID`
WHERE
`SiteTree_Live`.`Locale` = 'en_AU'
AND `SiteTree_Live`.`ClassName` = 'TourPage'
AND `DepartureDate`.`DepartureDate` LIKE '2013-03%'
You could also do a GROUP BY:
SELECT
COUNT(SiteTree_Live.ID)
FROM
`SiteTree_Live`
LEFT JOIN
`DepartureDate` ON `DepartureDate`.`TourID` = `SiteTree_Live`.`ID`
WHERE
`SiteTree_Live`.`Locale` = 'en_AU'
AND `SiteTree_Live`.`ClassName` = 'TourPage'
AND `DepartureDate`.`DepartureDate` LIKE '2013-03%'
GROUP BY
SiteTree_Live.ID
