我是oracle工作脚本的新手.我写了一些清除程序来清理所有旧数据并保留最近3个月的数据…程序执行成功.我也在手动调用时工作.程序如下:
CREATE OR REPLACE PROCEDURE Archive
IS
v_query varchar2(2048);
v_tablename VARCHAR2(50);
v_condition varchar2(50);
TYPE cur_typ IS REF CURSOR;
c cur_typ;
BEGIN
OPEN c for 'select tablename,columnname from pseb.purge_tables';
FETCH c INTO v_tablename,v_condition;
LOOP
EXIT WHEN c%NOTFOUND;
if(v_tablename ='cfw.DCTBLPERFCUMULATIVEMASTER') then
v_query:='delete from cfw.DCTBLPERFDCUMULATIVEB3MAINREG where cumulativeid in (select cumulativeid FROM '|| v_tablename || ' WHERE ' || v_condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete from cfw.DCTBLPERFDCUMULATIVEB4TODENERG where cumulativeid in (select cumulativeid FROM '|| v_tablename || ' WHERE ' || v_condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete from cfw.DCTBLPERDFCUMULATIVEB5MAXDEMAN where cumulativeid in (select cumulativeid FROM '|| v_tablename || ' WHERE ' || v_condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete from cfw.DCTBLPERFDCUMULATIVEB6TODREG where cumulativeid in (select cumulativeid FROM '|| v_tablename || ' WHERE ' || v_condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete from cfw.DCTBLPERFDCUMULATIVEB7MAXDEMAN where cumulativeid in (select cumulativeid FROM '|| v_tablename || ' WHERE ' || v_condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete from cfw.DCTBLPERFDCUMULATIVEB8MAXDEMAN where cumulativeid in (select cumulativeid FROM '|| v_tablename || ' WHERE ' || v_condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete FROM '|| v_tablename || ' WHERE ' || v_condition||' < sysdate-90';
execute immediate v_query;
else
begin
v_query:='delete FROM '|| v_tablename || ' WHERE ' || v_condition||' < sysdate-90';
execute immediate v_query;
end;
end if;
FETCH c INTO v_tablename,v_condition;
end LOOP;
close c;
END; --Procedure
我的JOb脚本如下:
begin
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'purgeproc_automation',job_type => 'STORED_PROCEDURE',job_action => 'call pseb.archive();',repeat_interval => 'FREQ=DAILY;INTERVAL=2',/* every other day */
auto_drop => false,enabled => true,comments => 'My new job');
end;
/
作业已成功创建,但作业状态失败,但未成功.它背后的原因是什么?它返回以下错误:
ORA-06550: line 1,column 728: PLS-00103: Encountered the symbol "PSEB" when expecting one of the following: := . ( @ % ; The symbol ":=" was substituted for "PSEB" to continue.
请指导我解决这个问题……
解决方法
哦,你的代码看起来很复杂.首先考虑这种简化:
CREATE OR REPLACE PROCEDURE Archive
IS
v_query varchar2(2048);
BEGIN
FOR REC IN (select tablename,columnname condition from pseb.purge_tables)
LOOP
if(rec.tablename ='cfw.DCTBLPERFCUMULATIVEMASTER') then
v_query:='delete from cfw.DCTBLPERFDCUMULATIVEB3MAINREG where cumulativeid in (select cumulativeid FROM '|| rec.tablename || ' WHERE ' || rec.condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete from cfw.DCTBLPERFDCUMULATIVEB4TODENERG where cumulativeid in (select cumulativeid FROM '|| rec.tablename || ' WHERE ' || rec.condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete from cfw.DCTBLPERDFCUMULATIVEB5MAXDEMAN where cumulativeid in (select cumulativeid FROM '|| rec.tablename || ' WHERE ' || rec.condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete from cfw.DCTBLPERFDCUMULATIVEB6TODREG where cumulativeid in (select cumulativeid FROM '|| rec.tablename || ' WHERE ' || rec.condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete from cfw.DCTBLPERFDCUMULATIVEB7MAXDEMAN where cumulativeid in (select cumulativeid FROM '|| rec.tablename || ' WHERE ' || rec.condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete from cfw.DCTBLPERFDCUMULATIVEB8MAXDEMAN where cumulativeid in (select cumulativeid FROM '|| rec.tablename || ' WHERE ' || rec.condition||' < sysdate-90';
execute immediate v_query;
v_query:='delete FROM '|| rec.tablename || ' WHERE ' || rec.condition||' < sysdate-90';
execute immediate v_query;
else
v_query:='delete FROM '|| rec.tablename || ' WHERE ' || rec.condition||' < sysdate-90';
execute immediate v_query;
end if;
END LOOP;
END; --Procedure
dbms_job.submit的替代作业定义:
declare
jid number;
begin
dbms_job.submit(
JOB => jid,WHAT => 'pseb.archive;',NEXT_DATE => SYSDATE,INTERVAL => 'sysdate +2');
end;

一种检查工作的方法:
select * from user_jobs;
