Re: How to schedule long running SQL job

From my laptop on powershell and dos prompt, it is saying tht pg_cron is not recognized.
Do I need anything new installation for this?
Thanks,
Sarwar

Try pg_cron. I know later versions support it.

Hi,
Db: Postgres
Cloud: aws / RDS
Tool using so far: PgAdmin

SQL got aborted after running for 1 hr 40 minutes from pgadmin.
I need CSV file output.
What is the recommended approach for this issue.

SQL:

SELECT P1.FILE_ID,

F.FILENAME,

P1.STAGE,

P1.SERIAL_NUMBER,

P1.TEST_IMAGE_SET_VALUE,

SUBSTRING(P1.SERIAL_NUMBER, '[A-Z][0-9]+') AS MCM_ID_SERIAL_NUMBER,

P1.RUN_ID,

SPLIT_PART(P1.RUN_ID, ':', 1) TEST_LOT

FROM BRONX.TEST_PART_DETAILS_ALL_MCM P1,

BRONX.FILES_METADATA F

WHERE F.FILE_ID = P1.FILE_ID

AND EXISTS ( SELECT SUBSTRING(P2.SERIAL_NUMBER, '[A-Z][0-9]+') AS MCM_ID2 ,

COUNT(DISTINCT SPLIT_PART(P2.RUN_ID, ':', 1)) AS NUM_DISTINCT_TEST_LOTS

FROM BRONX.TEST_PART_DETAILS_ALL_MCM P2

WHERE SUBSTRING(P2.SERIAL_NUMBER, '[A-Z][0-9]+') = SUBSTRING(P1.SERIAL_NUMBER, '[A-Z][0-9]+')

GROUP BY MCM_ID2

HAVING COUNT(DISTINCT SPLIT_PART(P2.RUN_ID, ':', 1)) > 1

)

order BY MCM_ID_SERIAL_NUMBER,

TEST_LOT

;

I used to use crontab or OEM to schedule these types jobs in the past. Now it is on RDS/AWS.
