本站中文解释

ALL_SCHEDULER_WINDOWS 视图显示了用户可以创建和使用的窗口。

Oracle 数据库调度器窗口允许用户配置作业和程序在不同的时间和日期来运行，而且这些作业和程序可以根据窗口的定义来重复运行。

要使用 ALL_SCHEDULER_WINDOWS 视图，可以使用以下语句查看用户所有的窗口：

SELECT * FROM ALL_SCHEDULER_WINDOWS;

要创建一个新窗口，可以使用DBMS_SCHEDULER.CREATE_WINDOWPLSQL 存储过程，如下所示：

BEGIN
DBMS_SCHEDULER.CREATE_WINDOW (
window_name => ‘my_window’,
repeat_interval=> ‘freq=daily’,
duration => NULL,
start_time => ’07:00am’,
end_time => ’11:00pm’
);
END;
/
