1
、建立儲存過程(
刪除臨時表)
：
createorreplaceproceduresp_gs_clear_temp_tablesis
tmp_tbl_namevarchar(
30);
sqltextvarchar(
255);
cursorcur_tmp_tablesisselectobject_namefromuser_objectswhereobject_namelike'tmp%'
andlength(object_name) >
13andobject_type =
'table'
andcreated < (sysdate-2);
begin
opencur_tmp_tables;
fetchcur_tmp_tablesintotmp_tbl_name;
loop
exitwhennotcur_tmp_tables%found;
sqltext :=
'drop table '
|| tmp_tbl_name;
executeimmediatesqltext;
fetchcur_tmp_tablesintotmp_tbl_name;
endloop;
closecur_tmp_tables;
endsp_gs_clear_temp_tables;
2
、建立job
sql> variable job1 number;
sql> begin
2dbms_job.submit(:job1,'sp_gs_clear_temp_tables;', sysdate,'sysdate+1/1440');
3end;
4/pl/sql procedure successfully completed
3
、執行job
sql> begin
2dbms_job.run(:job1);
3end;
4/pl/sql procedure successfully completed
4
、刪除job
sql> begin
2dbms_job.remove(:job1);
3end;
4/pl/sql procedure successfully completed
5
、計畫任務執**況監控
select * from user_jobs;--
檢視排程任務
select * from dba_jobs_running;--
檢視正在執行的排程任務
select * from dba_jobs;--
檢視執行完的排程任務
