寫在前面

需求

1.備份系統日誌表T_S_LOG, 按照操做時間字段OPERATETIME, 將天天的日誌增量備份到另外一張表.html

思路

1.建立一張數據結構徹底相同的表T_S_LOG_BAK做爲備份表sql

2.查出T_S_LOG中須要備份的數據數據結構

3.將數據賦給遊標變量oracle

4.遍歷遊標將數據逐條插入T_S_LOG_BAKide

5.建立無參存儲過程將遊標的這部分操做做爲存儲過程主體執行oop

6.建立定時任務定時執行該存儲過程測試

操做環境

操做步驟

1.建立備份表(上面貼了)

2.聲明遊標,定義記錄變量接收查詢出的數據,遍歷記錄插入到備份表,關閉遊標

 1 declare
 2   --定義遊標
 3   cursor cursor_log is
 4     select * from t_s_log where to_char(t_s_log.operatetime,'yyyyMMdd') = to_char(sysdate,'yyyyMMdd');
 5   --定義記錄變量
 6   ls_curinfo cursor_log%rowtype;
 7 begin
 8   open cursor_log;--打開遊標
 9   loop
10     FETCH cursor_log
11       INTO ls_curinfo;--獲取記錄值
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;--關閉遊標
34 end;

到這裏測試沒什麼問題就繼續建立存儲過程

3.建立無參存儲過程

存儲過程不細說了,大體結構就是:

CREATE OR REPLACE 
procedure 存儲過程名字 as
begin
...(過程體)...
end;

過程體就是第2步定義的遊標及遍歷那部分直接粘過來就能夠了

完整的存儲過程以下:(這裏用Navicat執行時遇到點問題, 改成PL/SQL執行沒問題, 不太清楚是什麼操做)

 1 CREATE OR REPLACE 
 2 procedure procedure_log_bak as
 3 begin
 4   declare
 5   --定義遊標
 6   cursor cursor_log is
 7     select * from t_s_log where to_char(t_s_log.operatetime,'yyyyMMdd') = to_char(sysdate,'yyyyMMdd');
 8   --定義記錄變量
 9   ls_curinfo cursor_log%rowtype;
10 begin
11   open cursor_log;--打開遊標
12   loop
13     FETCH cursor_log
14       INTO ls_curinfo;--獲取記錄值
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;--關閉遊標
37 end;
38 end;

到這裏手動執行存儲過程也沒問題就繼續建立定時任務,即Oracle的job

4.建立定時任務

使用PL/SQL找到DBMS_Jobs右鍵New...不細說了,能夠移步http://www.javashuo.com/article/p-ojhwrxit-dr.html這篇講的很詳細,這裏主要記錄一下建立完成後遇到的問題.當建立完成後job並無執行,Last_date這個字段是空的, 而且Next_date並非job定義的執行時間.

到這裏須要手動執行job:

執行以後last_date字段有值了,並且next_date的值也是想要定義的job執行時間了

到這裏就沒什麼問題了.

新需求補充

2.在日誌表T_S_LOG中插入一條記錄logcontent字段爲yyyyMMdd日誌備份成功.(後來提的需求)

思路

在存儲過程的最後, 也就是遍歷遊標的結束後新增insert語句便可.

不細說了,只說一下變量的拼接是用的||符號.例如:bak_date := bak_date||'日誌備份成功';

最新的存儲過程爲:

 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||'日誌備份成功';
 9   declare
10   --定義遊標
11   cursor cursor_log is
12     select * from t_s_log where to_char(t_s_log.operatetime,'yyyyMMdd') = to_char(sysdate,'yyyyMMdd');
13   --定義記錄變量
14   ls_curinfo cursor_log%rowtype;
15 begin
16   open cursor_log;--打開遊標
17   loop
18     FETCH cursor_log
19       INTO ls_curinfo;--獲取記錄值
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;--關閉遊標
42 end;
43   insert into t_s_log(id,logcontent,operatetime) values(gen_guid,bak_date,sysdate);
44 end;
