These many joins would impact the performance though!!
Only multiple join subqueries are supported.
below query works without any issue.
select * from (select id from test where id>10) a
join (select id from test where id>20) b on a.id=b.id;
In your case ,both filters are being used against same table(cust_focus) only otherwise you could have applied filters on different tables like above example.

I'm a bit stuck in my coding here... I have this extense and complex code, but I'm actually failling by the end of it. I'm getting the SQL Error [42804]: ERROR: argument of CASE/WHEN must be type boolean, not type character varying
The thing, is: when "bairro" matches a row from "SUB_COUNTRY_DB", get psd.name, else get z.name. Any tips on how I could accomplish this?
select distinct
aa.mes,
--aa.modalidade,
--to_date(aa.created_date, 'yyyy-mm-dd') data_captacao,
ucl.ja_comprou_lf as comprou_lf,
case when bairro in (select sub_country from sub_country_DB)
then psd.name
else z.name
end loja,
count (distinct aa.customer_uid) qtde_socios,
count (distinct aa.assinatura_uid) qtde_assinaturas
from assinaturas_ativas aa
left join ultima_compra_loja_fisica ucl on (aa.customer_uid = ucl.customer_uid
and aa.mes = ucl.mes)
left join zip_code z on (aa.customer_uid = z.customer_uid
and aa.mes = z.mes)
left join SUB_COUNTRY_DB psd
on (psd.district = aa.bairro)
group by 1,2,3--,4
Try variants like:
moving condition to an inner query
CASE WHEN EXISTS (SELECT DISTINCT sub_country FROM sub_country_DB WHERE sub_country = barrio)
ANY (PostgreSQL only)
CASE WHEN bairro = ANY(ARRAY_AGG(select sub_country from sub_country_DB))
I have a query that works on SQLAnywhere, but for some reason does not work on SSMS, tell me what is wrong with it, because I get an error: Cannot perform an aggregate function on an expression containing an aggregate or a subquery.
SELECT (CASE
WHEN EXISTS (select 1 from READCHK_READSEQ_OVRCOMP where READCHK_ID = :readChkId AND READSEQ_ID = :readSeqId) THEN 'M'
WHEN ( COUNT(*) = Coalesce(SUM((SELECT COUNT(*) FROM READCHKFLEX flx WHERE flx.READCHKFLD_ID = rcfld.READCHKFLD_ID AND flx.READCHK_ID = :readChkId) ), 0 )) THEN 'A'
ELSE 'I' END) CompletionStatus
FROM READSEQFLD rsfld
JOIN READSEQ rseq on rseq.READSEQ_ID = rsfld.READSEQ_ID
JOIN READCHKPAGEFLD rcpf on rcpf.READCHKTYPE_ID = rseq.READCHKTYPE_ID and rcpf.READCHKFLD_ID = rsfld.READCHKFLD_ID
JOIN READCHKFLD rcfld on rcfld.READCHKFLD_ID = rcpf.READCHKFLD_ID
WHERE rsfld.READSEQ_ID = :readSeqId
AND Upper(rsfld.ACTIVATE_FLG) = 'Y'
AND rcfld.CALFORM_ID IS NULL
AND (rcpf.fld_properties is null or Upper(rcpf.fld_properties) <> 'HIDE');
How to fix that?
SQL Server doesn't allow aggregates on expressions containing sub queries.
I think the following should preserve your original behaviour
Append a CTE definition before the existing SELECT
WITH flx_agg
AS (SELECT COUNT(*) AS Cnt,
READCHKFLD_ID
FROM READCHKFLEX flx
WHERE flx.READCHK_ID = :readChkId
GROUP BY READCHKFLD_ID)
SELECT ...
Add an outer join to that to your existing join conditions
LEFT JOIN flx_agg
ON flx_agg.READCHKFLD_ID = rcfld.READCHKFLD_ID
Change the offending CASE WHEN condition to
WHEN COUNT(*) = COALESCE(SUM(flx_agg.Cnt), 0)
I'm attempting to update the LAST_INSPECTION_FW field for all records in the VEHICLES_FW table with the last JOB_DATE_FW for records with the REASON_CODE_FW = 35. However, what's happening is that once the below code is executed, it's not taking into consideration the WHERE clause. This causes all of the records to update when it should just be updating those with the REASON_CODE_FW = 35.
Is there a way to restructure this code to get it working correctly? Please help, thanks!
UPDATE VEHICLES_FW
SET VEHICLES_FW.LAST_INSPECTION_FW = JOB_HEADERS_FW.FIELD2MAX
FROM VEHICLES_FW
INNER JOIN (SELECT VEHICLE_ID_FW, MAX(JOB_DATE_FW) AS FIELD2MAX
FROM JOB_HEADERS_FW
GROUP BY VEHICLE_ID_FW) AS JOB_HEADERS_FW
ON VEHICLES_FW.VEHICLE_ID_FW = JOB_HEADERS_FW.VEHICLE_ID_FW
INNER JOIN JOB_DETAILS_FW
ON JOB_NUMBER_FW = JOB_NUMBER_FW
WHERE REASON_CODE_FW = '35'
Common Table Expressions are your friend here. SQL Server's strange UPDATE ... FROM syntax is not. EG
with JOB_HEADERS_FW_BY_VEHICLE_ID as
(
SELECT VEHICLE_ID_FW, MAX(JOB_DATE_FW) AS FIELD2MAX
FROM JOB_HEADERS_FW
GROUP BY VEHICLE_ID_FW
), q as
(
Select VEHICLES_FW.LAST_INSPECTION_FW, JOB_HEADERS_FW_BY_VEHICLE_ID.FIELD2MAX NEW_LAST_INSPECTION_FW
FROM VEHICLES_FW
INNER JOIN JOB_HEADERS_FW_BY_VEHICLE_ID
ON VEHICLES_FW.VEHICLE_ID_FW = JOB_HEADERS_FW_BY_VEHICLE_ID.VEHICLE_ID_FW
INNER JOIN JOB_DETAILS_FW
ON JOB_NUMBER_FW = JOB_NUMBER_FW
WHERE REASON_CODE_FW = '35'
)
UPDATE q set LAST_INSPECTION_FW = NEW_LAST_INSPECTION_FW
I suspect this does what you want:
update v
set last_inspection_fw = (
select max(j.job_date_fw)
from job_headers_fw j
inner join job_details_fw jd on jd.job_number_fw = j.job_number_fw
where j.vehicle_id_fw = v.vehicle_id_fw and jd.reason_code_fw = 35
)
from vehicles_fw v

I get the error :
Column "vw_LiftEquip.category_id" is invalid in the ORDER BY clause because it is not contained in either an aggregate function or the GROUP BY clause.
Can't see why its returning that error, this is admittedly the first time I've ran a subquery on such a complex view, and I am a bit lost, thanks in advance for any help. I have looked through the similar posts and can find no answers to this one, sorry if I am just being dumb.
You are missing AND between EXPR11 = 'N' and (SELECT MAX(...
Otherwise, it looks OK. MAX without GROUP BY is allowed if you have no other columns in the SELECT
Update: #hvd also noted that you have nothing to compare to MAX(lifting_date). See comment
Update 2,
SELECT *
FROM vw_LiftEquip v1
CROSS JOIN
(
SELECT MAX(lifting_date) AS maxLift
FROM vw_LiftEquip
WHERE e_id = equipment_id
) v2
WHERE v1.lifting_loc = ? AND
v1.con_id = ? AND
v1.EXPR11 = 'N'
ORDER BY v1.lifting_ref_no,
v1.category_id,
v1.e_swl,
v1.e_serial
The example below stops at the first JOIN with an error message
Encountered " "JOIN" "JOIN "" at line 13, column 4. Was expecting: ")"
Am I missing something obvious with multiple joins in Bigquery?
SELECT type.CourseType AS CourseType,
SUM(joined.assign.StudentCount) AS StudentN
FROM
(
SELECT assign.StateCourseCode,
assign.StateCourseName,
assign.MatchType,
assign.Term,
assign.StudentCount
FROM [Assignment.AssignmentExtract5] AS assign
JOIN SELECT wgt.Term,
wgt.Weight
FROM [Crosswalk.TermWeights] AS wgt
ON wgt.Term = assign.Term
) AS joined
JOIN SELECT type.CourseCode,
type.CourseDescription,
type.CourseType,
type.CourseCategory
FROM [Crosswalk.CourseTypeDescription] AS type
ON joined.assign.StateCourseCode = type.CourseCode
GROUP BY CourseType
Thanks Ryan, your help was much appreciated. For anyone who might be interested, here is a query that worked.
SELECT type.CourseCategory AS CourseCategory,
SUM(joined.assign.StudentCount) AS StudentN
FROM
(
SELECT assign.StateCourseCode,
assign.StateCourseName,
assign.MatchType,
assign.Term,
assign.StudentCount
FROM [Assignment.AssignmentExtract5] AS assign
JOIN (SELECT Term,
Weight
FROM [Crosswalk.TermWeights]) AS wgt
ON wgt.Term = assign.Term
) AS joined
JOIN (SELECT CourseCode,
CourseDescription,
CourseType,
CourseCategory
FROM [Crosswalk.CourseTypeDescription]) AS type
ON (joined.assign.StateCourseCode = type.CourseCode)
GROUP BY CourseCategory;
I think you're just missing a parenthesis on line 13.
This:
JOIN SELECT wgt.Term,
wgt.Weight
FROM [Crosswalk.TermWeights] AS wgt
ON wgt.Term = assign.Term
Should be:
JOIN (SELECT wgt.Term,
wgt.Weight
FROM [Crosswalk.TermWeights]) AS wgt
ON wgt.Term = assign.Term
