问题描述
我需要在下面的作业每12小时运行一次（例如：作业需要每天在12:30 am和12:30 pm运行）
代码：
BEGIN
SYS.DBMS_JOB.CHANGE
(
job => 123,what => 'SP_ABC;',next_date => TO_DATE('08/09/2020 00:30:00','dd/mm/yyyy hh24:mi:ss'),INTERVAL => 'Trunc(sysdate+1)+30/1440'
);
END;
/
COMMIT;
解决方法
那将是这样的：
select t.task_id,x.ar[0] area,x.ar[1] iiid
from mytable t
cross join unnest(cast(t.json_data as array(array(varchar)))) as x(ar)
或者，如果您切换到SQL> set serveroutput on
SQL> declare
2 l_job number;
3 begin
4 dbms_job.submit
5 (job => l_job,6 what => 'p_test;',7 next_date => trunc(sysdate + 1) + 0/24 + 30/(24*60),8 interval => 'trunc(sysdate + 1) + 12/24 + 30/(24*60)'
9 );
10 commit;
11 dbms_output.put_line('job number = ' || l_job);
12 end;
13 /
job number = 151
PL/SQL procedure successfully completed.
SQL> select job,last_date,next_date from user_jobs;
JOB LAST_DATE NEXT_DATE
