I am writing an equivalent logic in BQ as in my source system. In source SQL server side it is working fine. But in Big query it is failing with the OR condition in the last left outer join condition. If I am moving the OR condition in the where clause it is giving wrong count. Need help to fix this issue. How can I re write the below query ?
SELECT count(*)
FROM stprof PRO
INNER JOIN stdim DIM
ON (DIM.diSet = PRO.diSet)
INNER JOIN DQConfig CFG
ON (CFG.ConSet = PRO.ConSet)
LEFT OUTER JOIN AgSt CCT
ON (CCT.StSet = PRO.StSet)
INNER JOIN stprof SummPRO
ON (SummPRO.diSet = DIM.SummdiSet AND
SummPRO.dIntervalStart = PRO.dIntervalStart AND
SummPRO.SiteId = PRO.SiteId AND
SummPRO.nDuration = PRO.nDuration)
LEFT OUTER JOIN AgSt SummCCT
ON (SummCCT.StSet = SummPRO.StSet)
LEFT OUTER JOIN AgentStatus SummSTS
ON (
SummSTS.StSet = SummPRO.StSet
OR
SummSTS.StSet = PRO.StSet)
WHERE DIM.cType = 'A'
You can replace LEFT JOIN with CROSS JOIN and move condition from ON clause to WHERE clause as in below example
#standardSQL
SELECT COUNT(*)
FROM stprof PRO
INNER JOIN stdim DIM
ON DIM.diSet = PRO.diSet
INNER JOIN DQConfig CFG
ON CFG.ConSet = PRO.ConSet
LEFT OUTER JOIN AgSt CCT
ON CCT.StSet = PRO.StSet
INNER JOIN stprof SummPRO
ON SummPRO.diSet = DIM.SummdiSet
AND SummPRO.dIntervalStart = PRO.dIntervalStart
AND SummPRO.SiteId = PRO.SiteId
AND SummPRO.nDuration = PRO.nDuration
LEFT OUTER JOIN AgSt SummCCT
ON SummCCT.StSet = SummPRO.StSet
CROSS JOIN AgentStatus SummSTS
WHERE DIM.cType = 'A'
AND (
SummSTS.StSet = SummPRO.StSet
OR SummSTS.StSet = PRO.StSet
)
SELECT Count(TRK.REACTIE_ID),

I can't figure out why I can't get only the first row back.
Now I get three rows back with null values and I want only to get the first row. Please help!
rows without nulls use the following FROM statement and keep the rest of query the same.:
FROM CATEGORIEEN_KOPPELTABEL CK
JOIN CATEGORIE C ON C.CATEGORIE_ID = CK.CATEGORIE_ID
JOIN TV_SHOW S ON S.TV_SHOW_ID = CK.TV_SHOW_ID AND S.NAAM = 'South Park'
JOIN TVSHOW_REACTIES_KOPPELTABEL TRK ON TRK.TV_SHOW_ID = S.TV_SHOW_ID
i want to innerjoin more than 3 tables in one select query in one database all of them are having rm_id as a common column but i want to display the rows of all tables in one sql query is it possible if it is then i would hearly request u to provide some code
select * from
bk_det inner join
bk_rep inner join
bk_sec inner join
mut_det inner join
rm_det inner join
soil_det
on
bk_det.rm_id = bk_rep.rm_id = bk_sec.rm_id = mut_det.rm_id = rm_det.rm_id = soil_det.rm_id
You need an on clause for each inner join. e.g.
select * from a
inner join b on a.id = b.id
inner join c on b.id = c.id
You are missing the ON clause for each join:
select *
from bk_det
inner join bk_rep
on bk_det.rm_id = bk_rep.rm_id
inner join bk_sec
on bk_rep.rm_id = bk_sec.rm_id
inner join mut_det
on bk_sec.rm_id = mut_det.rm_id
inner join rm_det
on mut_det.rm_id = rm_det.rm_id
inner join soil_det
on rm_det.rm_id = soil_det.rm_id
Note: you will have to check the join condition column names since I do not know your table structure
If you need help with learning join syntax, here is a great visual explanation of joins.
Since you are using an INNER JOIN this will return records if the rm_id exists in each table.
You might need to use a LEFT JOIN:
select *
from bk_det
left join bk_rep
on bk_det.rm_id = bk_rep.rm_id
left join bk_sec
on bk_rep.rm_id = bk_sec.rm_id
left join mut_det
on bk_sec.rm_id = mut_det.rm_id
left join rm_det
on mut_det.rm_id = rm_det.rm_id
left join soil_det
on rm_det.rm_id = soil_det.rm_id
While debugging into some Oracle code, I came across this query:
SELECT TPM_TASK.TASKID FROM TPM_GROUP
INNER JOIN TPM_USERGROUPS ON TPM_GROUP.GROUPID = TPM_USERGROUPS.GROUPID
INNER JOIN TPM_TASK
INNER JOIN TPM_GROUPTASKS ON TPM_TASK.TASKID = TPM_GROUPTASKS.TASKID
INNER JOIN TPM_PROJECTVERSION ON TPM_TASK.PROJECTID = TPM_PROJECTVERSION.PROJECTID AND TPM_TASK.VERSIONID = TPM_PROJECTVERSION.VERSIONID
INNER JOIN TPM_TASKSTAGE ON TPM_TASK.STAGEID = TPM_TASKSTAGE.STAGEID
INNER JOIN TPM_PROJECTSTAGE ON TPM_PROJECTVERSION.STAGEID = TPM_PROJECTSTAGE.STAGEID
ON TPM_GROUP.GROUPID = TPM_GROUPTASKS.GROUPID
I'm confused by the line:
INNER JOIN TPM_TASK
I haven't seen a JOIN without an ON clause before. Also confusing is the line:
ON TPM_GROUP.GROUPID = TPM_GROUPTASKS.GROUPID
This seems like a random ON clause without any matching JOIN. The query runs without any errors, and returns a bunch of data, so obvious the syntax is perfectly valid. Can someone shed some light on exactly what's going on here?
Small universe... I ran across a tool generating this syntax yesterday and was rather flummoxed.
Apparently,
FROM a
INNER JOIN b
INNER JOIN c ON (b.id = c.id)
ON (a.id = c.id)
is equivalent to a nested subquery
FROM a
INNER JOIN (SELECT <<list of columns>>
FROM b
INNER JOIN c ON (b.id=c.id)) c
ON (a.id = c.id)
I think that this is only a problem of ordering your query (since there are only INNER JOINs, the order of them is not really that important). I rearrenged your query and now it looks like this:
SELECT TPM_TASK.TASKID
FROM TPM_GROUP
INNER JOIN TPM_USERGROUPS
ON TPM_GROUP.GROUPID = TPM_USERGROUPS.GROUPID
INNER JOIN TPM_GROUPTASKS
ON TPM_GROUP.GROUPID = TPM_GROUPTASKS.GROUPID
INNER JOIN TPM_TASK
ON TPM_TASK.TASKID = TPM_GROUPTASKS.TASKID
INNER JOIN TPM_PROJECTVERSION
ON TPM_TASK.PROJECTID = TPM_PROJECTVERSION.PROJECTID
AND TPM_TASK.VERSIONID = TPM_PROJECTVERSION.VERSIONID
INNER JOIN TPM_TASKSTAGE
ON TPM_TASK.STAGEID = TPM_TASKSTAGE.STAGEID
INNER JOIN TPM_PROJECTSTAGE
ON TPM_PROJECTVERSION.STAGEID = TPM_PROJECTSTAGE.STAGEID
Does it make more sense to you now?, it does to me.
It'd look fine if it had parenthesis in there...
SELECT TPM_TASK.TASKID
FROM
TPM_GROUP
INNER JOIN TPM_USERGROUPS ON TPM_GROUP.GROUPID = TPM_USERGROUPS.GROUPID
INNER JOIN (
TPM_TASK
INNER JOIN TPM_GROUPTASKS ON TPM_TASK.TASKID = TPM_GROUPTASKS.TASKID
INNER JOIN TPM_PROJECTVERSION ON TPM_TASK.PROJECTID = TPM_PROJECTVERSION.PROJECTID
AND TPM_TASK.VERSIONID = TPM_PROJECTVERSION.VERSIONID
INNER JOIN TPM_TASKSTAGE ON TPM_TASK.STAGEID = TPM_TASKSTAGE.STAGEID
INNER JOIN TPM_PROJECTSTAGE ON TPM_PROJECTVERSION.STAGEID = TPM_PROJECTSTAGE.STAGEID
) ON TPM_GROUP.GROUPID = TPM_GROUPTASKS.GROUPID
but since they are all inner joins I agree with Lamak's answer.

I am writing sql query to implement different scenario, but problem is that it gives repeated values. I write distinct and order by too but result was same can any one help me to solve this issue.

Yeah, since you're doing a crap ton of Cartesian products with those joins without on clauses, that will cause plenty of what seem like 'repeated values', but are really just the product of the two tables combining sets.
