Select rows from related table which matches different conditions - sql

I have a table called places which looks like this:
and another table called place_addons_saved which looks like this:
How can I write a query that relates place_addons_saved.place and places.id and searches rows that matches ONLY places which have all the conditions?
For example when I'll search for rows that have place_addon = 163, place_option = 329 and place_addon = 162, place_option = 324 will return place with id of a 80, but when I'll search for rows that have place_addon = 162, place_option = 326 and place_addon = 163, place_option = 330 the query must return nothing, because place 80 doesn't fit the 2nd condition

If I understand correctly, you can use group by and having:
select place
from place_addons_saved
where (place_addon = 163 and place_option = 329) or
(place_addon = 162 and place_option = 324)
group by place
having count(*) = 2; -- "2" is the number of comparisons
To get all the information about the places:
select p.*
from places p
where p.id in (select place
from place_addons_saved
where (place_addon = 163 and place_option = 329) or
(place_addon = 162 and place_option = 324)
group by place
having count(*) = 2; -- "2" is the number of comparisons
);

This could work:
With GetResult (place,chk1,chk2) As
(
SELECT
pas.place,
sum(Case When (pas.place_addon = 163) AND (pas.place_option = 329) then 1 Else 0 End) As chk1,
sum(Case When (pas.place_addon = 162) AND (pas.place_option = 324) then 1 Else 0 End) As chk2
FROM
places AS p RIGHT OUTER JOIN
place_addons_saved AS pas ON p.id = pas.place
group by pas.place
)
Select * From GetResult Where chk1 > 0 and chk2 > 0

How Can I to count the gender when is M or F, somehting like
SELECT count(N.gender)
FROM `DATABASE_T` as T
LEFT JOIN `DATABASE_N` as N
ON
T.ENCUESTA = N.ENCUESTA AND
T.P_DEPTO = N.P_DEPTO AND
T.P_MUNIC = N.P_MUNIC AND
T.COD_VEREDA = N.COD_VEREDA AND
T.PAIS = N.PAIS and

SELECT countif(N.gender = 'M') as M, countif(N.gender = 'F') as F
FROM `DATABASE_T` as T
LEFT JOIN `DATABASE_N` as N
ON
T.ENCUESTA = N.ENCUESTA AND
T.P_DEPTO = N.P_DEPTO AND

T.COD_VEREDA = N.COD_VEREDA AND
T.PAIS = N.PAIS and
T.UC_UO = N.UC_UO
WHERE N.ID_PROD=1
Since you did not describe the structure of your table and use Spanish-looking identifiers, I will use a clearer example with my own schema:
SELECT
SUM( CASE WHEN Sex = 'M' THEN 1 ELSE 0 END ) AS M,
SUM( CASE WHEN Sex = 'F' THEN 1 ELSE 0 END ) AS F
FROM People
WHERE People.Dept = 5

How to update this Select Query to Update? - So far, it just hangs

I eventually managed to get what I was after by grouping and then applying an additional filter with 'HAVING' which is probably not the best way to go about it, but I am new to SQL and this is the only way I could achieve what I was after... which was a list of 'simple' items where the 'qty' is 0 and the range status (attribute_id = 168) is Discontinued (ID 96) and the 'status' (attribute_id = 97) is enabled (id = 1). This is shown below:
SELECT
`mgic_catalog_product_entity`.`sku` AS `sku`,
`mgic_catalog_product_entity`.`type_id` AS `type_id`,
`mgic_cataloginventory_stock_item`.`qty` AS `qty`,
MAX(Case WHEN `mgic_eav_attribute`.`attribute_id` = 97 THEN `mgic_catalog_product_entity_int`.`value` END) AS status,
MAX(Case WHEN `mgic_eav_attribute`.`attribute_id` = 168 THEN `mgic_catalog_product_entity_int`.`value` END) AS range_status
FROM (((`mgic_eav_attribute`
join `mgic_catalog_product_entity_int` on ((`mgic_eav_attribute`.`attribute_id` = `mgic_catalog_product_entity_int`.`attribute_id`)))
join `mgic_catalog_product_entity` on ((`mgic_catalog_product_entity_int`.`entity_id` = `mgic_catalog_product_entity`.`entity_id`)))
join `mgic_cataloginventory_stock_item` on ((`mgic_catalog_product_entity_int`.`entity_id` = `mgic_cataloginventory_stock_item`.`product_id`)))
WHERE `mgic_catalog_product_entity`.`type_id` = 'simple' AND `mgic_cataloginventory_stock_item`.`qty` = 0
GROUP BY `mgic_catalog_product_entity`.`sku`
HAVING status = 1 and range_status = 96;
I am now trying to amend this to an update instruction to set the 'status' (attribute_id = 97) to disabled (id = 2) for the results list of the below query.
update mgic_eav_attribute ea join
mgic_catalog_product_entity_int cpei on ea.attribute_id = cpei.attribute_id join
mgic_catalog_product_entity cpe on cpei.entity_id = cpe.entity_id join
mgic_cataloginventory_stock_item cisi on cpei.entity_id = cisi.product_id
set cpei.value = 2
WHERE cpe.type_id = 'simple' AND ((ea.attribute_code = 'status') and
(cpei.value = 1)) AND cisi.qty = 0 AND EXISTS(
SELECT
cpe.sku,
cpe.type_id,
cisi.qty,
MAX(Case WHEN ea.attribute_id = 97 THEN cpei.value END) AS status,
MAX(Case WHEN ea.attribute_id = 168 THEN cpei.value END) AS range_status
FROM (((`mgic_eav_attribute`
join `mgic_catalog_product_entity_int` on ((`mgic_eav_attribute`.`attribute_id` = `mgic_catalog_product_entity_int`.`attribute_id`)))
join `mgic_catalog_product_entity` on ((`mgic_catalog_product_entity_int`.`entity_id` = `mgic_catalog_product_entity`.`entity_id`)))
join `mgic_cataloginventory_stock_item` on ((`mgic_catalog_product_entity_int`.`entity_id` = `mgic_cataloginventory_stock_item`.`product_id`)))
WHERE `mgic_catalog_product_entity`.`type_id` = 'simple' AND `mgic_cataloginventory_stock_item`.`qty` = 0
GROUP BY cpei.entity_id
HAVING status = 1 and range_status = 96);
The above query just seems to hang and doesn't execute. Can anyone help?

sql how to add inner join and multiple conditions to filter

I have this query
SELECT DISTINCT IP.IRId
FROM cmp.NPTable NP
INNER JOIN IPTable IP ON IP.IPtId = NP.IPd
LEFT JOIN IPCTable IPC ON IPC.IPId = NP.IPId
WHERE NP.PCN Id = #PCNId
AND (IP.IsCompliant = 1 AND IPC.CheckId = 1) OR (IP.IsCompliant = 0 AND IPC.CheckId = 1)
This is not working correcty
THe IPTable either has IsCompliant = null, 0 or 1 -- this is basically to indicate true or false
IPC.CheckId is either 1 or 2 -- this is the primary ID in this table
The only match integer match is the value 1 between the two tables.
I only want to bring back rows if IsCompliant = 1 and CheckId = 1
else if IsCompliant is null or 0, then CheckId = 2.
The clause I added to my where which is
AND (IP.IsCompliant = 1 AND IPC.CheckId = 1) OR (IP.IsCompliant = 0 AND IPC.CheckId = 1)
This does not work. Help. Will be very appreciated.
Thanks
WHERE NP.PCN Id = #PCNId
AND
(
(IP.IsCompliant = 1 AND IPC.CheckId = 1) OR
((IP.IsCompliant is null or IP.IsCompliant = 0) AND IPC.CheckId = 2)
)

Understanding case expression in the "Where" clause

I've got this code here and you can see from my Pseudocode what I'm trying to accomplish
select *
from dbo.BenefitsForms
inner join Dependents on BenefitsForms.UserId = Dependents.BenefitsForm_UserId
inner join CoverageLevels on BenefitsForms.MedicalId = CoverageLevels.Id
where (BenefitsForms.MedicalId > 0 AND BenefitsForms.MedicalId < 13)
AND Dependents.IsSpouse = CASE when CoverageLevels.[Level] = 2 then 1
when CoverageLevels.[Level] = 3 then 0 end
when CoverageLevels.[Level] = 4 then [any, it doesnt matter] <--- my desire but it doesn't work.
What can I do to get the effect I desire in the brackets? If Coverage Level = 4 then I don't care what Dependents.IsSpouse is, I don't even need to sort by it anymore.
Assuming that isSpouse can only be 0 or 1... if CoverageLevels.Level is 4, then compare isSpouse to itself, which will always result in true:
AND Dependents.IsSpouse = CASE
when CoverageLevels.[Level] = 2 then 1
when CoverageLevels.[Level] = 3 then 0
when CoverageLevels.[Level] = 4 then Dependents.IsSpouse
END
Alternately, this can also be expressed without the CASE:
WHERE
BenefitsForms.MedicalId > 0
AND BenefitsForms.MedicalId < 13
AND (
(Dependents.IsSpouse = 1 AND CoverageLevels.[Level] = 2)
OR (Dependents.IsSpouse = 0 AND CoverageLevels.[Level] = 3)
OR CoverageLevels.[Level] = 4
)

SQL Counting Records with Count and Having

I'm having problems with what I thought was a simple query to count records:
SELECT req_ownerid, count(req_status_lender) AS total6
FROM bor_requests
WHERE (req_status_lender = 0 AND req_status_borrower = 0) OR
(req_status_lender = 1 AND req_status_borrower = 1)
GROUP BY req_ownerid
HAVING req_ownerid = 70
I thought this would count all the records where (req_status_lender = 0 AND req_status_borrower = 0) and (req_status_lender = 1 AND req_status_borrower = 1) and then give me the total but it only gives me the total for either (req_status_lender = 0 AND req_status_borrower = 0) or (req_status_lender = 1 AND req_status_borrower = 1).
Any ideas what I'm doing wrong?
You should use the HAVING clause only to limit on something that's been aggregated in your query above - e.g. if you want to select all those rows where a SUM(....) or COUNT(...) is larger than say 5, then you'd use HAVING SUM(...) > 5
What you're doing here is a standard WHERE clause - add it there!
SELECT req_ownerid, count(req_status_lender) AS total6
FROM bor_requests
WHERE req_ownerid = 70
AND ((req_status_lender = 0 AND req_status_borrower = 0) OR
(req_status_lender = 1 AND req_status_borrower = 1))
GROUP BY req_ownerid
