I am trying to perform a merge to insert and update as the case may be in a table. However in table 1, I only want it to insert the unique values of the tbl2.rfc field regardless if my other fields change, I only want to show the unique values of said field. I am occupying the ROW_NUMBER function to bring only unique values, but I have not been able to add this function to my merge.
MERGE INTO B69_TBL1 tbl1
USING (SELECT T1.*, ROW_NUMBER() OVER (PARTITION BY T1.rfc ORDER BY T1.rfc DESC) ENUMERADO
FROM B69_TBL2 tbl2
WHEN MATCHED THEN
UPDATE SET
tbl1.id_tbl1 = tbl2.id_con,
tbl1.rfc = tbl2.rfc,
tbl1.rfc = tbl2.name_cont
WHEN NOT MATCHED THEN
INSERT (tbl1.id_tbl1,tbl1.tbl1tipo,tbl1.id_concentrado,tbl1.rfc,
tbl1.name_cont,tbl1.baja_logica,tbl1.last_update)
VALUES (id_tbl1autt.nextval,'1','1',tbl2.id_concentrado,tbl2.rfc,
tbl2.name_cont,'0', '11/05/2021')
) T1
WHERE ENUMERADO=1
AND RFC IS NOT NULL
The error it marks is 00907. 00000 - "missing right parenthesis"
because I had it like this and it fails precisely in the on.
MERGE INTO B69_TBL1 tbl1
USING (SELECT T1.*, ROW_NUMBER() OVER (PARTITION BY T1.rfc ORDER BY T1.rfc DESC) ENUMERADO
ON tbl1.rfc = tbl2.rfc
FROM B69_TBL2 tbl2 )
WHEN MATCHED THEN
UPDATE SET
tbl1.id_alert = tbl2.id_con,
tbl1.rfc = tbl2.rfc,
tbl1.rfc = tbl2.name_cont
WHEN NOT MATCHED THEN
INSERT (tbl1.id_alert,tbl1.alertype,tbl1.id_con,tbl1.rfc,
tbl1.name_cont,tbl1.baja_logica,tbl1.last_update)
VALUES (id_tbl1autt.nextval,'1','1',tbl2.id_con,tbl2.rfc,
tbl2.name_cont,'0', '11/05/2021')
) T1
WHERE ENUMERADO=1
AND RFC IS NOT NULL
Your ON clause is in the wrong place;
You had the tbl2 alias inside the USING query instead of following it;
You do not need the tbl1 aliases before the destination column names in the UPDATE or INSERT;
You are updating the rfc column twice (I removed the second instance);
There was a strange T1 alias after the insert that should be inside the USING query; and
You can use a DATE literal rather than a string.
There may be other errors, as I do not have your tables to test the query.
MERGE INTO B69_TBL1 tbl1

SELECT T1.*,
ROW_NUMBER() OVER (PARTITION BY T1.rfc ORDER BY T1.rfc DESC) AS ENUMERADO

i will get latest record by timestamp but it is not filter desired
output
here is code i was try to get latest record bu it is not work me.i will attach a image for better understanding.can you figure out that problems
select *
from (select
id,NPCI_REFMSGID,TO_CHAR (created_date, 'dd.mm.rrrr hh24:mi:ss.ff3')AS created_Date,
rank() over (partition by ID order by TO_CHAR (created_date, 'dd.mm.rrrr hh24:mi:ss.ff3') desc) r
from emnd_tblemandate_mst
--where end_enrollment_date is null
)
where r = 1 AND NPCI_REFMSGID='1ea345bc63644b53a88076040ef979e3'
You are partitioning by ID so you get all rows in your result.
Think it should be
select *
from (select id
, NPCI_REFMSGID
, TO_CHAR (created_date, 'dd.mm.rrrr hh24:mi:ss.ff3')AS created_Date
, rank() over (partition by NPCI_REFMSGID order by created_date desc) r
from emnd_tblemandate_mst
)
where r = 1
AND NPCI_REFMSGID = '1ea345bc63644b53a88076040ef979e3'
Then you get only the newest record for a specific NPCI_REFMSGID
Please help me with next problem:
And the result should be:
filtered by iban_code distinct
You can use row_number analytical function.
Select * from
(Select t.*,
Row_number()
over (partition by per_id, iban_code
order by main_bank_account desc) as rn
From your_table t)
Where rn=1;
Cheers!!
Same query running in Db2 , but in oracle it's giving error.
Please help. thanks in advance.
delete from (SELECT
EMP_ID,
SAL,
ROW_NUMBER() OVER (PARTITION BY EMP_ID ORDER BY SAL DESC) As RN
FROM FPM.FACT_PL_BS
WHERE MEASUREMENT_PERIOD_ID=20170811
AND SCENARIO_ID=1) A where RN>1}
Check documentation Notes on Updatable Views:
The view must not contain any of the following constructs:
A set operator
A DISTINCT operator
An aggregate or analytic function
A GROUP BY, ORDER BY, MODEL, CONNECT BY, or START WITH clause
A collection expression in a SELECT list
A subquery in a SELECT list
A subquery designated WITH READ ONLY
Joins, with some exceptions, as documented in Oracle Database Administrator's Guide
ROW_NUMBER is an Analytic Function, so update is not permitted.
I think this one should work (not tested):
delete from FPM.FACT_PL_BS
WHERE ROWID =ANY
(SELECT ROW_ID
FROM
(SELECT ROWID as ROW_ID,
EMP_ID,
SAL,
ROW_NUMBER() OVER (PARTITION BY EMP_ID ORDER BY SAL DESC) As RN
FROM FPM.FACT_PL_BS
WHERE MEASUREMENT_PERIOD_ID=20170811
AND SCENARIO_ID=1)
WHERE RN > 1;
or maybe
delete from FPM.FACT_PL_BS
WHERE MEASUREMENT_PERIOD_ID=20170811
AND SCENARIO_ID=1
AND ROWID <>ALL
(select MAX(ROWID) KEEP (DENSE_RANK FIRST ORDER BY SAL) OVER (PARTITION BY EMP_ID)
FROM FPM.FACT_PL_BS)
select A.*
from Incident_Audit_log a where incident_audit_log_id in
(select top 1 incident_audit_log_id from Incident_Audit_log b
where b.incident_id=a.incident_id and b.status_did=a.status_did
and b.tracking_code_did = (select tracking_code_did
from Incident_Audit_log where update_date = (select MAX(update_date)
from Incident_Audit_log where Status_did in (103, 1035)
and incident_id = b.incident_id)
and incident_id = b.incident_id)
order by update_date asc)
I am not sure what you want to achieve but I guess that you want to extract row with new newest update and status_did equal to 13 and 1035.
In that case this should work:
select *
from (
select ROW_NUMBER() OVER(ORDER BY update_date DESC) AS rn,
*
from Incident_Audit_log
where status_did in (103, 1035)
) as SubQueryAlias
where rn = 1
In case not , provide more info.
