A selection query that returns job_id (s) to cancel. |

Cancel multiple jobs
To cancel multiple jobs, nest a SELECT
clause that retrieves job_id
(s) inside the CANCEL JOBS
statement:
> CANCEL JOBS (SELECT job_id FROM [SHOW JOBS]
WHERE user_name = 'maxroach');
All jobs created by maxroach
will be cancelled.
Cancel automatic table statistics jobs
Canceling an automatic table statistics job is not useful since the system will automatically restart the job immediately. To permanently disable automatic table statistics jobs, disable the sql.stats.automatic_collection.enabled
cluster setting:
> SET CLUSTER SETTING sql.stats.automatic_collection.enabled = false;
Cancel jobs for a schedule
To cancel jobs for a specific backup schedule, use the schedule's id
:
> CANCEL JOBS FOR SCHEDULE 590204387299262465;
CANCEL JOBS FOR SCHEDULES 1
You can also CANCEL multiple schedules by nesting a SELECT
clause that retrieves id
(s) inside the CANCEL JOBS
statement:
> CANCEL JOBS FOR SCHEDULES SELECT id FROM [SHOW SCHEDULES] WHERE label = 'test_schedule';
CANCEL JOBS FOR SCHEDULES 2
