Custom mysql query with time_range in Subquery (range from filter box)
ralphkretzschmar opened a new issue #9199: Custom mysql query with time_range in Subquery (range from filter box)
URL: https://github.com/apache/incubator-superset/issues/9199
Hello together,
first of all i'm very new to superset and aswell making my first steps with mysql queries regarding BI.
So please forgive me for my lack of knowledge and give me a hint if i could do better.
If i'm wrong here, please let me know where to ask :)
We are trying to gather certain data with subqueries from a vtiger instance.
But the SQL Engine transforms the query in such a case, that it doesn't get the needed data.
What i try to achieve are the following steps:
1. getting history data from a vtiger within a certain range (=time_range)
2. sort it by date descending
3. deduplicate by CRMID (grouped by crmid)
### Here is the query i use to get the data:
-----------------------
select *
from
(
select
vtiger_modtracker_basic.crmid,
vtiger_modtracker_basic.changedon,
vtiger_modtracker_basic.status,
vtiger_modtracker_detail.fieldname,
vtiger_modtracker_detail.prevalue,
vtiger_modtracker_detail.postvalue,
vtiger_potential.potentialname,
vtiger_potential.potentialid,
vtiger_potential.campaignname,
vtiger_potentialscf.cf_948 AS Projectname
from
vtiger_modtracker_basic Inner join
vtiger_modtracker_detail On vtiger_modtracker_detail.id = vtiger_modtracker_basic.id Inner join
vtiger_potential On vtiger_potential.potentialid = vtiger_modtracker_basic.crmid Inner Join
vtiger_potentialscf On vtiger_potentialscf.potentialid = vtiger_potential.potentialid
where
(vtiger_modtracker_basic.crmid, vtiger_modtracker_basic.changedon, vtiger_modtracker_detail.fieldname) in
(
select vtiger_modtracker_basic.crmid, vtiger_modtracker_basic.changedon, vtiger_modtracker_detail.fieldname
from vtiger_modtracker_basic inner join
vtiger_modtracker_detail On vtiger_modtracker_detail.id = vtiger_modtracker_basic.id
where vtiger_modtracker_detail.fieldname = 'sales_stage'
AND vtiger_modtracker_basic.changedon {{ time_range }}
group by vtiger_modtracker_basic.crmid
)
order by vtiger_modtracker_basic.changedon DESC LIMIT 50000
) AS selection
group by selection.crmid
-----------------------
what you expected to happen:
1. that the "time_range" placeholder is removed by selected time_range
2. that the query is not modified.
### Actual results - when i take a look at the query how it will be run
SELECT postvalue AS postvalue,
count(*) AS count
FROM
(select *
from
(select vtiger_modtracker_basic.crmid,
vtiger_modtracker_basic.changedon,
vtiger_modtracker_basic.status,
vtiger_modtracker_detail.fieldname,
vtiger_modtracker_detail.prevalue,
vtiger_modtracker_detail.postvalue,
vtiger_potential.potentialname,
vtiger_potential.potentialid,
vtiger_potential.campaignname,
vtiger_potentialscf.cf_948 AS Projectname
from vtiger_modtracker_basic
Inner join vtiger_modtracker_detail On vtiger_modtracker_detail.id = vtiger_modtracker_basic.id
Inner join vtiger_potential On vtiger_potential.potentialid = vtiger_modtracker_basic.crmid
Inner Join vtiger_potentialscf On vtiger_potentialscf.potentialid = vtiger_potential.potentialid
where (vtiger_modtracker_basic.crmid,
vtiger_modtracker_basic.changedon,
vtiger_modtracker_detail.fieldname) in
(select vtiger_modtracker_basic.crmid,
vtiger_modtracker_basic.changedon,
vtiger_modtracker_detail.fieldname
from vtiger_modtracker_basic
inner join vtiger_modtracker_detail On vtiger_modtracker_detail.id = vtiger_modtracker_basic.id
where vtiger_modtracker_detail.fieldname = 'sales_stage'
AND vtiger_modtracker_basic.changedon
group by vtiger_modtracker_basic.crmid)
order by vtiger_modtracker_basic.changedon DESC
LIMIT 18446744073709551610) AS selection
group by selection.crmid) AS expr_qry
WHERE changedon >= STR_TO_DATE('1920-02-25 00:00:00.000000', '%Y-%m-%d %H:%i:%s.%f')
GROUP BY postvalue
ORDER BY count DESC
LIMIT 50000;
what actually happens.
Getting wrong data because the time range is not in the subquery anymore
Thank you for your help in advance :)

How did you construct this query and chart? The subquerying happens when you go from sqllab -> explore. If you can compose your chart in the explore view then it shouldn’t run in a subquery.

Thank you for the hint, but i wasn't able to find a way to create a query in the explore view.
Should i post this in slack?
Best ralph
