I have a query below. Is this the right way to do a subquery?
SELECT App.State_Pstl_Name,
COUNT (DISTINCT App.APLCTN_ID) AS Total_APLCTN
FROM (Select count(distinct b.APLCTN_ID ),

I am working on a SQL statement that will become a part of a view. What I need is to extract only the records that have the same unique key twice. The query looks like below right now.
select distinct
rscmaster_no_in, rsc_no_in, calendar_year, calendar_month,
Wstat_Abrv_Ch,
h.Wstat_no_in, Staffing_Calendar_Date, payhours,
l.OTStatus
from
vw_all_ts_hire h
left join
MCFRS_OTStatus_Lookup l on l.wstat_no_in = h.Wstat_no_in
where
rscmaster_no_in in (select rscmaster_no_in from vw_rsc_ECC_splty)
and Wstat_Abrv_Ch <> ''
and h.Wstat_no_in in (103, 107)
and l.OTStatus in ('ECCOTRemove', 'ECCOTSignup')
and Staffing_Calendar_Date = '2020-11-01' -- only for the testing purposes. Will be removed later.
order by
RscMaster_no_in
The result I get from the query above is:
I need to modify the SQL statement so that the end result is like below:
How can I modify the above statement to spit out the end result like that?
Use the analytic count(*) over () function.
with cte as (
select
count(*) over (partition by YourUniqueKey) as MyRowCount
{rest of your query}
)
select *
from cte
where MyRowCount = 2;
This should give you the results you want (performance is dependent on indexes/table design).
This takes your core logic and puts it into a sub select that only returns records that have a count > 1.
Then use those ID's to select all the data you need but only for those ID's that are in the sub select with count > 1
select distinct rscmaster_no_in,rsc_no_in, calendar_year, calendar_month,
Wstat_Abrv_Ch, h.Wstat_no_in, Staffing_Calendar_Date, payhours ,l.OTStatus
from vw_all_ts_hire h
left join MCFRS_OTStatus_Lookup l on l.wstat_no_in = h.Wstat_no_in
WHERE rscmaster_no_in IN (
SELECT rscmaster_no_in
from vw_all_ts_hire h
left join MCFRS_OTStatus_Lookup l on l.wstat_no_in = h.Wstat_no_in
where rscmaster_no_in in (select rscmaster_no_in from vw_rsc_ECC_splty)
and Wstat_Abrv_Ch <> ''
and h.Wstat_no_in in (103, 107)
and l.OTStatus in ('ECCOTRemove', 'ECCOTSignup')
and Staffing_Calendar_Date = '2020-11-01' -- only for the testing purposes. Will be removed later.
GROUP BY rscmaster_no_in
HAVING COUNT(*) > 1
)
order by RscMaster_no_in
You can use COUNT(*) OVER () window function such as
SELECT *
FROM
(
SELECT COUNT(*) OVER (PARTITION BY rscmaster_no_in) AS cnt,
t.*
FROM tab t
) t
WHERE cnt>1
AND OTStatus = 'ECCOTRemove'
This may help you :
select * from (
select distinct
rscmaster_no_in, rsc_no_in, calendar_year, calendar_month,
Wstat_Abrv_Ch,
h.Wstat_no_in, Staffing_Calendar_Date, payhours,
l.OTStatus,
SELECT COUNT(*) OVER (PARTITION BY rscmaster_no_in) AS uinqueCount
from
vw_all_ts_hire h
left join
MCFRS_OTStatus_Lookup l on l.wstat_no_in = h.Wstat_no_in
where
rscmaster_no_in in (select rscmaster_no_in from vw_rsc_ECC_splty)
and Wstat_Abrv_Ch <> ''
and h.Wstat_no_in in (103, 107)
and l.OTStatus in ('ECCOTRemove', 'ECCOTSignup')
and Staffing_Calendar_Date = '2020-11-01' -- only for the testing purposes. Will be removed later.
) innerReult
where uinqueCount=2 --Or uinqueCount>1 base on your business
order by
RscMaster_no_in
I'd need help on this matter.
my where condition does not get accepted ... I know that is tricky the case in the where clause, so i think you could let me out... I created a field into a subquery with a over partition by, which then i bring into the main select ... then I'd need to apply the filter you see below... it returns me an error saying that B does not exist even tough if I just write B.CC = 1 then it gives me result...
any ideas?
Thanks in advance

This answers the original version of the question.
In Teradata, you can simplify the logic to:
SELECT ...,
Count(A.COD_ABI) Over (PARTITION BY A.COD_ABI, A.COD_KTO) AS CC
FROM A
QUALIFY CC > 1 AND DATE_EST IS NOT NULL;

For sure I couldn't understand very well your query. You could improve your post for next time.
As answer, I think you should encapsulate your select statment and group by using your select as subquery. It is not the best approach but it may works fine.

I have the following query where I unique records for patient_id, meaning patient_id should not be duplicate. Each time I try executing the query, seems like the DB hangs or it takes hours to execute, I'm not sure. I need my records to load quickly. Any quick resolution will be highly appreciated.

OR (SELECT (a.psdate - c.psdate) FROM dual) <=-7)

For start, you have a cartesian product with PATIENT_STUDY_STEP (pss).
It is not connected to anything.

Error I am getting is:
Error Code: -204, SQL State: 42704
I would say that a good option here would be to use a CTE, or Common Table Expression. You can do something similar to the following:
WITH CTE_X AS(
SELECT VAL_A
,VAL_B
FROM TABLE_A)
,CTE_Y AS(
SELECT VAL_C
,VAL_B
FROM TABLE_B)
SELECT VAL_A
,VAL_B
FROM CTE_X X
JOIN CTE_Y Y
ON X.VAL_A = Y.VAL_C;
While this isn't specific to your example, it does show that CTE's create a sort of temporary "in memory" table that you can access in a subsequent query. This should allow you to issue your inner two subselects as a CTE, and then use the CTE in the "SELECT MAX( MAX_DATE - MIN_DATE ) AS NUM_CONS_DAYS" query.
You cannot reference columns from the outer select in the subselect, no more than 1 level deep anyway. If I correctly understand what you're doing, you'll probably need to join DWH.MQT_SUMMARY_WATER_READINGS and DWH.DWH_WMETER_CONTEXT in the outer select.
