I know this is a 101 question, but do I need to repeat the Where clause in the main query in the sub-query below? It appears to give me the same either way, but is it even needed?
FROM account a
LEFT JOIN account pa ON a.parentaccountid = pa.accountid
JOIN customeraddress ca ON a.accountid = ca.parentid
JOIN optionsetmetadata osm ON osm.entityname = 'customeraddress'
AND osm.optionsetname = 'addresstypecode'
AND ca.addresstypecode = osm.[option]
LEFT JOIN sik_warehouse w ON a.sik_warehouseid = w.sik_warehouseid
LEFT JOIN sik_deliverymethods dm ON a.sik_deliverymethodid = dm.sik_deliverymethodsid
WHERE a.accountnumber IN ('58398',
'4350',
'5076',
'4310',
'15847')
AND Addresstypecode = 2
AND ca.jms_status = 100000000
AND ca.addressnumber > (
SELECT TOP 1 ca_sub1.addressnumber
FROM customeraddress ca_sub1
JOIN account a_sub1 ON ca_sub1.parentid = a_sub1.accountid
AND ca_sub1.addressnumber > 2
order by ca_sub1.addressnumber ASC
add inline view if you want to put multiple where condition.

I have 2 selects. The first one:
select purs.t_orno as purchased
from ttisfc001201 sls
inner join twhinr110201 sfc on sfc.t_orno = sls.t_pdno
inner join twhltc100201 purs on purs.t_clot=sfc.t_clot
left join twhltc220201 items on items.t_clot = sfc.t_clot
left join twhltc210201 cert_num on cert_num.t_item = items.t_item
left join twhltc200201 cert on cert.t_ltft = cert_num.t_ltft
where sls.t_cprj = 'SLS004336' and purs.t_orno like N'PUR%'
and sfc.t_koor = 1 and sfc.t_kost = 5
Is giving me these results:
PUR007833
PUR008544
PUR008698
PUR008963
PUR009048
PUR009304
PUR009611
PUR009912
PUR009913
PUR010006
PUR010110
PUR010400
PUR010465
PUR010539
PUR010664
So basically these are results I must use in the second select in where clause. A field from table in second select must be equal to one of them. To understand me better it should look like this:
select distinct fac.t_isup
from ttfacp200201 fac
inner join ttfacp250201 mid on mid.t_ityp = fac.t_ttyp and mid.t_idoc=fac.t_ninv
where mid.t_orno ='PUR010400' or mid.t_orno='PUR009912'or mid.t_orno='PUR009913'or mid.t_orno='PUR010465'or mid.t_orno='PUR008544'or mid.t_orno='PUR008963'or mid.t_orno='PUR009048'or mid.t_orno='PUR010110'or mid.t_orno='PUR007833'or mid.t_orno='PUR009304'or mid.t_orno='PUR009611'or mid.t_orno='PUR010664'or mid.t_orno='PUR010006'or mid.t_orno='PUR010539'or mid.t_orno='PUR008698'or mid.t_orno='PUR010667'
All these ORs are results from the first select. How I can combine them (the first select to go in second select where clause) so I can get results at once?
You can use the IN clause for your second query
select distinct fac.t_isup
from ttfacp200201 fac
inner join ttfacp250201 mid on mid.t_ityp = fac.t_ttyp and mid.t_idoc=fac.t_ninv
where mid.t_orno IN (
select purs.t_orno
from ttisfc001201 sls
inner join twhinr110201 sfc on sfc.t_orno = sls.t_pdno
inner join twhltc100201 purs on purs.t_clot=sfc.t_clot
left join twhltc220201 items on items.t_clot = sfc.t_clot
left join twhltc210201 cert_num on cert_num.t_item = items.t_item
left join twhltc200201 cert on cert.t_ltft = cert_num.t_ltft
where sls.t_cprj = 'SLS004336' and purs.t_orno like N'PUR%'
and sfc.t_koor = 1 and sfc.t_kost = 5
)
Something like this
;with first_query_cte(purchased) as (
select purs.t_orno
from ttisfc001201 sls
inner join twhinr110201 sfc on sfc.t_orno = sls.t_pdno
inner join twhltc100201 purs on purs.t_clot=sfc.t_clot
left join twhltc220201 items on items.t_clot = sfc.t_clot
left join twhltc210201 cert_num on cert_num.t_item = items.t_item
left join twhltc200201 cert on cert.t_ltft = cert_num.t_ltft
where sls.t_cprj = 'SLS004336' and purs.t_orno like N'PUR%'
and sfc.t_koor = 1 and sfc.t_kost = 5)
select distinct fac.t_isup
from ttfacp200201 fac
inner join ttfacp250201 mid on mid.t_ityp = fac.t_ttyp and mid.t_idoc=fac.t_ninv
inner join first_query_cte fqc on mid.t_orno=fqc.purchased;
I want to extract a ID , User_ID value from one of the Companies and Contract tables, depending on the ContorollerName value.
select P.TitleProject, P.StartDateProject, P.EndDateProject,P.ControllerID,P.RecordID,P.IsAllocated,P.ProjectStatus_ID,
CN.ControllerName,CN.PersianName,
PU.ProjectID,PU.UserID,PU.RoleID,
CASE
WHEN CN.ControllerName = 'Company' THEN
Companies.Id,Companies.[User_Id]
WHEN CN.ControllerName = 'Contract' THEN
Contracts.Id,Contracts.[User_Id]
END
from Projects P
left outer join Controllers CN ON P.ControllerID = CN.Id
left outer join ProjectUsers PU ON P.Id = PU.ProjectID
where P.IsAllocated = 1
For example, if ContorollerName is 'Company' , the select command is as follows :
select P.TitleProject, P.StartDateProject, P.EndDateProject,P.ControllerID,P.RecordID,P.IsAllocated,P.ProjectStatus_ID,
CN.ControllerName,CN.PersianName,
PU.ProjectID,PU.UserID,PU.RoleID,
Companies.Id,Companies.[User_Id]
You are on the right track -- using left join. But you need to add the tables to the from clause with the appropriate logic.
The logic for the join is quite unclear. The query looks something like this:
select . . .,
coalesce(c.id, co.id) as id,
coalesce(c.user_id, co.user_id) as user_id
from Projects P left join
Controllers CN
on P.ControllerID = CN.Id left join
ProjectUsers PU
on P.Id = PU.ProjectID left join
companies c
on c.? = ? and -- no idea what the right join conditions are
c.ControllerName = 'Company' left join
contracts co
on co.? = ? and -- no idea what the right join conditions are
co.ControllerName = 'Contract'
where P.IsAllocated = 1
I'm stuck on an exercise where I need to count the total amount of unique visits to planets, but if the planet is the moon (maan), then it should be counted twice. Also the client number should be 121
select case
when objectnaam = 'Maan' then count(objectnaam)
else count(distinct objectnaam)
end as aantal_bezoeken
from klanten inner join deelnames on klanten.klantnr = deelnames.klantnr
inner join reizen on deelnames.reisnr = reizen.reisnr
inner join bezoeken on reizen.reisnr = bezoeken.reisnr
where klanten.klantnr = 121
group by objectnaam
And it gives me this result
aantal_bezoeken
1
4
1
1
but the result should be
aantal_bezoeken
7
I just need to add all these values together but I don't know how to,
or maybe there's a better more simple solution. It should be without subqueries
Try this:
select sum(aantal_bezoeken) as aantal_bezoeken from
(select case
when objectnaam = 'Maan' then count(objectnaam)
else count(distinct objectnaam)
end as aantal_bezoeken
from klanten inner join deelnames on klanten.klantnr = deelnames.klantnr
inner join reizen on deelnames.reisnr = reizen.reisnr
inner join bezoeken on reizen.reisnr = bezoeken.reisnr
where klanten.klantnr = 121
group by objectnaam) as a
Here's the structure of my database (used to collect info from a survey):
question_responses->answer_choices->subquestions->questions->survey
| ^
V |
submissions->response_group<----------------------------survey_deployment
where A->B means A has the PK of B
So, I want to get the responses of a particular user; let's say that his submission pk is 1. I had written the query
select question_responses.answer_text
from submissions join question_responses on (question_responses.submission_pk = submission.pk)
join answer_choices on (question_responses.answer_choices_pk = answer_choices.pk)
join subquestions on (answer_choices.subquestions_pk = subquestions.pk)
right join questions on (subquestions.questions_pk = questions.pk)
where submissions.pk = 1
order by questions.order
It is possible to not answer questions. In such a case, there is no question_responses.pk recorded. I would still like to be able to account for skipping, so I need this record to be returned, even if there is no response. I thought that the right join would have accounted for this record, but apparently not.
Any help is greatly appreciated.
Because you have submissions.pk = 1 in the where clause this effectively turns your outer join into an inner join, since any missing submission will have a pk of null. and null = 1 is not true.
You could rewrite your query using a LEFT JOIN, and selecting from questions:
select question_responses.answer_text
from questions
left join (subquestions
inner join answer_choices
on answer_choices.subquestions_pk = subquestions.pk
inner join question_responses
on question_responses.answer_choices_pk = answer_choices.pk
inner join submissions
on question_responses.submission_pk = submission.pk)
on subquestions.questions_pk = questions.pk
and submissions.pk = 1
order by questions.order;
This is similar to doing something like:
select subquery.answer_text
from questions
left join
( select question_responses.answer_text, subquestions.questions_pk
from subquestions
inner join answer_choices
on answer_choices.subquestions_pk = subquestions.pk
inner join question_responses
on question_responses.answer_choices_pk = answer_choices.pk
inner join submissions
on question_responses.submission_pk = submission.pk
where submissions.pk = 1
) subquery
on subquery.questions_pk = questions.pk
order by questions.order;
but depending on your dbms the former may perform better as it has no derived tables.
Check out this, does it help?
SELECT question_responses.answer_text
FROM questions LEFT JOIN subquestions on (subquestions.questions_pk = questions.pk)
LEFT JOIN answer_choices on (answer_choices.subquestions_pk = subquestions.pk)
LEFT JOIN question_responses on (question_responses.answer_choices_pk = answer_choices.pk)
LEFT JOIN submissions on (question_responses.submission_pk = submission.pk)
WHERE submissions.pk = 1
ORDER BY questions.order
I am trying to update a date in a table, based off of a MAX(date) in another table. To get the correct data to link up, I have to do 2 inner joins and 2 left outer joins.
I can select the correct data, it returns a Guid (PersonId) and the Date.
I have to use this information to update my original table. I am having trouble getting this to work, I still getting syntax errors.
update tblqualityassignments as assign
inner join tblrequirementteams as team on assign.guidmemberid = team.guidmemberid
set assign.dtmQAPCLed = dtmTaken
from
(
select reg.guidpersonid, max(certs.dtmTaken) as dtmTaken from tblqualityassignments as assign
inner join tblrequirementteams as team on assign.guidmemberid = team.guidmemberid
inner join tblregisteredusercerts as reg on team.guidpersonid = reg.guidpersonid
left outer join tblcerttaken as certs on certs.guidcertid = reg.guidcertid
left outer join tblCodesCertType as types on types.intcerttypeid = certs.intcerttypeid
where types.intcerttypeid = 1
and assign.guidmemberid = team.guidmemberid
group by reg.guidpersonid as data
)
where data.guidpersonid = team.guidpersonid
Assuming you are using SQL Server for this, then this should work:
UPDATE A
SET A.dtmQAPCLed = dtmTaken
FROM tblqualityassignments AS A
INNER JOIN tblrequirementteams as T
ON A.guidmemberid = T.guidmemberid
INNER JOIN (select reg.guidpersonid, max(certs.dtmTaken) as dtmTaken
from tblqualityassignments as assign
inner join tblrequirementteams as team
on assign.guidmemberid = team.guidmemberid
inner join tblregisteredusercerts as reg
on team.guidpersonid = reg.guidpersonid
left outer join tblcerttaken as certs
on certs.guidcertid = reg.guidcertid
left outer join tblCodesCertType as [types]
on [types].intcerttypeid = certs.intcerttypeid
where [types].intcerttypeid = 1
and assign.guidmemberid = team.guidmemberid
group by reg.guidpersonid) data
ON T.guidpersonid = data.guidpersonid
