Question

我有多个时间表，我想将它们全部提供给作业的repeat_interval。但是，我找不到办法做到这一点 - Oracle文档说这是可能的，但我找不到任何例子。任何帮助表示赞赏。这是我尝试过的，但它不起作用：

ORA-06512：第2行27418. 00000 - “重复间隔或日历中的语法错误”

*原因：重复间隔或日历定义不是              被认为是有效的语法。

begin
    dbms_scheduler.create_schedule('SCHED1', 
          repeat_interval => 'FREQ=DAILY;BYHOUR=9;BYMINUTE=55');
    dbms_scheduler.create_schedule('SCHED2', 
          repeat_interval => 'FREQ=DAILY;BYHOUR=15;BYMINUTE=15'); 
    DBMS_SCHEDULER.CREATE_JOB(
          JOB_NAME           =>  'SCHED_TEST_JOB',
          JOB_TYPE           =>  'STORED_PROCEDURE',
          JOB_ACTION         =>  'SCHED_TEST_JOB_PROCEDURE',
          START_DATE         =>  SYSDATE,
          REPEAT_INTERVAL    =>  'FREQ=SCHED1,SCHED2;',
          AUTO_DROP          =>  FALSE,
          ENABLED            =>  FALSE);
end;

Answer 1

我认为你在create_job重复间隔结束时有一个多余的分号。

syntax是：

combined_schedule = schedule_list [";" include_clause][";" exclude_clause] [";" intersect_clause]

... schedule_list是：

schedule_list = schedule_clause ("," schedule_clause)

您是否希望合并时间表，如下所示：

SQL>  BEGIN
  2    dbms_scheduler.create_schedule('sched1',
  3            repeat_interval => 'FREQ=YEARLY;
  4                                BYDATE=0130,0220,0725');
  5    dbms_scheduler.create_schedule('sched2',
  6           repeat_interval => 'FREQ=MONTHLY;
  7                               INTERVAL=2;
  8                               BYMONTHDAY=15;
  9                               BYHOUR=9,17;
 10                               INCLUDE=sched1');
 11  END;
 12  /

DBMS_SCHEDULER如何为作业的repeat_interval提供多个计划？
