database - 如何在程序中使用 DBA_JOBS

Question

我想在deadjob时发送sendmsg。所以我需要DBA_JOBS在程序中选择如何DBA_JOBS在我尝试此代码的程序中使用：

SELECT COUNT(*)
  FROM DBA_JOBS
 WHERE JOB in('539','639','679','719','919','1359');

但是这个错误阻止了我的新程序

ORA-00942表或视图不存在

Answer 1

您不需要被授予dba_jobs使用整个数据库所需的视图。改用user_jobs视图：

SELECT COUNT(*) as count
  FROM USER_JOBS
 WHERE JOB in('539','639','679','719','919','1359');

Answer 2

您需要明确授予此视图的读取权限。
