篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了oracle定时执行存储过程的时间区间问题相关的知识，希望对你有一定的参考价值。
每天在 01:00:00 和 07:00:00 之间、每 2 小时 执行 一次 每天在 16:00:00 和 23:59:59 之间、每 2 小时 执行一次。
存储过程已经写好，大侠们帮帮忙吧，这个job该怎么写呀
1:00
3:00
5:00
7:00
16:00
18:00
20:00
22:00
CREATE OR REPLACE PROCEDURE other_proc
AS
vHour VARCHAR(2);
BEGIN
vHour := TO_CHAR(SYSDATE, 'HH24');
IF vHour = '01' OR vHour = '03' OR vHour = '05' OR vHour = '07'
OR vHour = '16' OR vHour = '18' OR vHour = '20' OR vHour = '22' THEN
-- 调用你那个存储过程.
-- 由于没有代码， 暂时写 NULL;
NULL;
END IF;
END;
/
variable jobno number;
begin
dbms_job.submit(:jobno, 'other_proc;', trunc(sysdate+1/24,'HH'), 'trunc(SYSDATE+1/24,''HH'')');
commit;
end;
/ 参考技术A DECLARE
v_date VARCHAR2(8) := '20130312';
v_date1 DATE := to_date(v_date, 'yyyymmdd');
BEGIN
LOOP
过程名字(v_date);
v_date1 := v_date1 + 2/24;
v_date := to_char(v_date1, 'yyyymmdd');
EXIT WHEN v_date1 >= SYSDATE;
END LOOP;
END;
你的存储过程里面应该判断当前时间是否在那个时间区间
Oracle定时任务执行存储过程备份日志记录表
写在前面
需求
备份系统日志表T_S_LOG, 按照操作时间字段OPERATETIME, 将每天的日志增量备份到另一张表.
思路
1.创建一张数据结构完全相同的表T_S_LOG_BAK作为备份表
2.查出T_S_LOG中需要备份的数据
3.将数据赋给游标变量
4.遍历游标将数据逐条插入T_S_LOG_BAK
5.创建无参存储过程将游标的这部分操作作为存储过程主体执行
6.创建定时任务定时执行该存储过程
操作环境
Oracle11g

操作步骤
1.创建备份表(上面贴了)
2.声明游标,定义记录变量接收查询出的数据,遍历记录插入到备份表,关闭游标
1 declare 2 --定义游标 3 cursor cursor_log is 4 select * from t_s_log where to_char(t_s_log.operatetime,‘yyyyMMdd‘) = to_char(sysdate,‘yyyyMMdd‘); 5 --定义记录变量 6 ls_curinfo cursor_log%rowtype; 7 begin 8 open cursor_log;--打开游标 9 loop 10 FETCH cursor_log 11 INTO ls_curinfo;--获取记录值 12 EXIT WHEN cursor_log%NOTFOUND; 13 insert into t_s_log_bak(ID, 14 BROSWER, 15 LOGCONTENT, 16 LOGLEVEL, 17 NOTE, 18 OPERATETIME, 19 OPERATETYPE, 20 USERID, 21 USERNAME, 22 REALNAME) values(ls_curinfo.ID, 23 ls_curinfo.BROSWER, 24 ls_curinfo.LOGCONTENT, 25 ls_curinfo.LOGLEVEL, 26 ls_curinfo.NOTE, 27 ls_curinfo.OPERATETIME, 28 ls_curinfo.OPERATETYPE, 29 ls_curinfo.USERID, 30 ls_curinfo.USERNAME, 31 ls_curinfo.REALNAME); commit; 32 end loop; 33 close cursor_log;--关闭游标 34 end;
到这里测试没什么问题就继续创建存储过程
3.创建无参存储过程
存储过程不细说了,大致结构就是:
CREATE OR REPLACE procedure 存储过程名字 as begin ...(过程体)... end;
过程体就是第2步定义的游标及遍历那部分直接粘过来就可以了
完整的存储过程如下:(这里用Navicat执行时遇到点问题, 改为PL/SQL执行没问题, 不太清楚是什么操作)
1 CREATE OR REPLACE 2 procedure procedure_log_bak as 3 begin 4 declare 5 --定义游标 6 cursor cursor_log is 7 select * from t_s_log where to_char(t_s_log.operatetime,‘yyyyMMdd‘) = to_char(sysdate,‘yyyyMMdd‘); 8 --定义记录变量 9 ls_curinfo cursor_log%rowtype; 10 begin 11 open cursor_log;--打开游标 12 loop 13 FETCH cursor_log 14 INTO ls_curinfo;--获取记录值 15 EXIT WHEN cursor_log%NOTFOUND; 16 insert into t_s_log_bak(ID, 17 BROSWER, 18 LOGCONTENT, 19 LOGLEVEL, 20 NOTE, 21 OPERATETIME, 22 OPERATETYPE, 23 USERID, 24 USERNAME, 25 REALNAME) values(ls_curinfo.ID, 26 ls_curinfo.BROSWER, 27 ls_curinfo.LOGCONTENT, 28 ls_curinfo.LOGLEVEL, 29 ls_curinfo.NOTE, 30 ls_curinfo.OPERATETIME, 31 ls_curinfo.OPERATETYPE, 32 ls_curinfo.USERID, 33 ls_curinfo.USERNAME, 34 ls_curinfo.REALNAME); commit; 35 end loop; 36 close cursor_log;--关闭游标 37 end; 38 end;
到这里手动执行存储过程也没问题就继续创建定时任务,即Oracle的job
4.创建定时任务
使用PL/SQL找到DBMS_Jobs右键New...不细说了,可以移步https://www.cnblogs.com/yx007/p/6519544.html这篇讲的很详细,这里主要记录一下创建完成后遇到的问题.当创建完成后job并没有执行,Last_date这个字段是空的, 并且Next_date并不是job定义的执行时间.
到这里需要手动执行job:
执行之后last_date字段有值了,而且next_date的值也是想要定义的job执行时间了
到这里就没什么问题了.
