如何获取Oracle SCHEDULE 的REPEAT_INTERVAL 分钟格式?
how to get the REPEAT_INTERVAL in minutes format of Oracle SCHEDULE?
我正在使用 Oracle 11g 数据库,Oracle DB 中的重复间隔被定义为字符串格式,如 FREQ=MINUTELY; INTERVAL=10;
。有什么方法可以将其转换为 +00 00:10:00.000000
这种格式吗?
使用DBMS_SCHEDULER.EVALUATE_CALENDAR_STRING
和一些转换函数将日历字符串转换为间隔格式。
declare
v_next_run_date date;
v_start_date date := date' 2000-01-01';
v_interval interval day(2) to second;
begin
dbms_scheduler.evaluate_calendar_string
(
calendar_string => 'FREQ=MINUTELY; INTERVAL=10;',
start_date => v_start_date,
return_date_after => v_start_date,
next_run_date => v_next_run_date
);
--Convert dates to timestamps, subtraction then converts to interval.
v_interval :=
cast(v_next_run_date as timestamp)
-
cast(v_start_date as timestamp);
dbms_output.put_line(v_interval);
end;
/
输出:
+00 00:10:00.000000
