我想每天從表中提取數據
你可以使用DBMS_SCHEDULER創建工作和時間表日常運行。
例如，下面的作業將每小時運行一次：
SQL> BEGIN
2 DBMS_SCHEDULER.DROP_JOB (JOB_NAME => 'test_full_job_definition');
3 END;
4/
PL/SQL procedure successfully completed.
SQL>
SQL> BEGIN
2 DBMS_SCHEDULER.create_job (
3 job_name => 'test_full_job_definition',
4 job_type => 'PLSQL_BLOCK',
5 job_action => 'BEGIN my_job_procedure; END;',
6 start_date => SYSTIMESTAMP,
7 repeat_interval => 'freq=hourly; byminute=0; bysecond=0;',
8 end_date => NULL,
9 enabled => TRUE,
10 comments => 'Job defined entirely by the CREATE JOB procedure.');
11 END;
12/
PL/SQL procedure successfully completed.
SQL>
SQL> SELECT JOB_NAME, ENABLED FROM DBA_SCHEDULER_JOBS where job_name ='TEST_FULL_JOB_DEFINITION'
2/
JOB_NAME ENABL
---------------------------------------- -----
TEST_FULL_JOB_DEFINITION TRUE
SQL>
將它保存在我的本地機器在Excel工作表
這是一個經常被問到的問題和人們經常在CSV文件和Microsoft Excel文件之間感到困惑。生成CSV文件可能很容易，因爲它使用SQL * Plus。要將輸出寫入Excel文件，您需要以編程方式執行。
您可以使用下面的code開發的Anton Scheffer：

嘿Lalit，我知道關於dbms_scheduler部分。我的問題是我如何將桌面數據發送到桌面的C盤。你能否建議我一些簡短的方法。我很感謝你的努力，但是我必須在今天之前完成，上面的代碼將花費很多時間來分析和實施。希望很快聽到你的聲音。 – Famy

@Famy我認爲實現上面的代碼不會浪費時間，因爲有示例提供瞭如何使用它。您只需要傳遞目錄名稱等。 –

最低要求的辦法是達利一些計劃作業
create table myexportable as (select sysdate exportdate, q.* from mytable q)
RESP插入表中的數據爲一些臨時表。
insert into myexportable (select sysdate exportdate, q.* from mytable q)
，然後利用SQL Plus中
set serveroutput on;
set linesize 10000;
set pagesize 10000;
set heading off;
set feed 0;
set trimspool on;
set colsep '|';
spool exptable.out;
select * from myexportable where trunc(exportdate) = trunc(sysdate)
/
quit;
導出數據，並將它們至少進口管道分隔文本文件導入Excel。

有很多方法。該流程需要多少自動化？產品是否需要採用Excel格式，或者僅僅是Excel打開並且格式可讀的東西？ –
產品需要以excel格式保存。 – Famy
是的，但直接？即時創建CSV文件非常簡單。將CSV導入Excel並保存爲XLS（X）非常簡單。讓Oracle在沒有手動操作的情況下吐出一個XLS（X）不必太困難，但確切的路徑取決於您的需求。 Google'pl sql write to excel file' for some examples，並且考慮詢問一個更具體的問題。 –
