  SCHEDULE EVERY <interval>
  [DAY | HOUR | MINUTE | WEEK | MONTH | YEAR]
  [START AT <start_time>]
  [END AT <end_time>]
  [ENABLED | DISABLED];
Copy after login
  • <job_name>:作业名称
  • <schema.procedure_name>:要执行的存储过程或函数
  • <parameters>:存储过程或函数所需的参数
  • <interval>:执行时间间隔
  • <start_time>:开始时间(可选)
  • <end_time>:结束时间(可选)
  • ENABLED | DISABLED:指定作业是否启用(可选,默认启用)

2. 启用作业

ALTER JOB <job_name> ENABLE;
Copy after login

3. 禁用作业

ALTER JOB <job_name> DISABLE;

CREATE JOB my_job
WITH
  PROCEDURE pkg1.proc1()
  SCHEDULE EVERY 1 HOUR
  ENABLED;
Copy after login
