Oracle定时任务执行存储过程备份日志记录表

写在前面

需求

1.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.

新需求补充

2.在日志表T_S_LOG中插入一条记录logcontent字段为yyyyMMdd日志备份成功.(后来提的需求)

思路

在存储过程的最后, 也就是遍历游标的结束后新增insert语句即可.

不细说了,只说一下变量的拼接是用的||符号.例如:bak_date := bak_date||'日志备份成功';

最新的存储过程为:

 1 CREATE OR REPLACE 
 2 procedure procedure_log_bak as
 3 gen_guid varchar2(100);
 4 bak_date varchar2(100);
 5 begin
 6   select sys_guid() into gen_guid from dual;
 7   select to_char(sysdate,'yyyyMMdd') into bak_date from dual;
 8   bak_date := bak_date||'日志备份成功';
 9   declare
10   --定义游标
11   cursor cursor_log is
12     select * from t_s_log where to_char(t_s_log.operatetime,'yyyyMMdd') = to_char(sysdate,'yyyyMMdd');
13   --定义记录变量
14   ls_curinfo cursor_log%rowtype;
15 begin
16   open cursor_log;--打开游标
17   loop
18     FETCH cursor_log
19       INTO ls_curinfo;--获取记录值
20     EXIT WHEN cursor_log%NOTFOUND;
21    insert into t_s_log_bak(ID,
22       BROSWER,
23       LOGCONTENT,
24       LOGLEVEL,
25       NOTE,
26       OPERATETIME,
27       OPERATETYPE,
28       USERID,
29       USERNAME,
30       REALNAME) values(ls_curinfo.ID,
31       ls_curinfo.BROSWER,
32       ls_curinfo.LOGCONTENT,
33       ls_curinfo.LOGLEVEL,
34       ls_curinfo.NOTE,
35       ls_curinfo.OPERATETIME,
36       ls_curinfo.OPERATETYPE,
37       ls_curinfo.USERID,
38       ls_curinfo.USERNAME,
39       ls_curinfo.REALNAME); commit;
40   end loop;
41   close cursor_log;--关闭游标
42 end;
43   insert into t_s_log(id,logcontent,operatetime) values(gen_guid,bak_date,sysdate);
44 end;

同样,修改后用PL/SQL执行即可修改成功.
