+- `SHOW IMPORT JOB <job-id>`
 
 ## Required privileges
 
-- `SHOW IMPORT JOBS`: if a user has the `SUPER` privilege, this statement shows all import jobs in TiDB. Otherwise, this statement only shows jobs created by the current user.
+- `SHOW IMPORT JOBS`: by default, this statement only shows jobs created by the current user. To view all import jobs, you need the `SUPER` privilege.
