Re: How to schedule long running SQL job

Do: select * from rds.allowed_extensions; and see if it’s in your version support. I don’t quite recall which versions supports it other than v.12.X where X is another value like 4, 5, or 6. If it is in the list, try: create extension pg_cron; note you may need superuser to create it.



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.

Thanks,
