ADMIN CANCEL DDL

The ADMIN CANCEL DDL statement allows you to cancel a running DDL job. The job_id can be found by running ADMIN SHOW DDL JOBS.

Synopsis

AdminStmt:

NumList:

Examples

To cancel the currently running DDL jobs and return whether the corresponding jobs are successfully cancelled, use ADMIN CANCEL DDL JOBS:

{{< copyable "sql" >}}

ADMIN CANCEL DDL JOBS job_id [, job_id] ...;

If the operation fails to cancel the jobs, specific reasons are displayed.

Note:

• Only this operation can cancel DDL jobs. All other operations and environment changes (such as machine restart and cluster restart) cannot cancel these jobs.
• This operation can cancel multiple DDL jobs at the same time. You can get the ID of DDL jobs using the ADMIN SHOW DDL JOBS statement.
• If the jobs you want to cancel are finished, the cancellation operation fails.

MySQL compatibility
