我想每天从表格中提取数据
您可以使用 DBMS_SCHEDULER 创建作业和计划以便每天运行。
例如，以下作业将每小时运行一次：
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>
将它保存在excel表中的本地计算机中
这是常见问题，人们经常会在 CSV 文件和 Microsoft Excel 文件之间感到困惑。使用 SQL * Plus 生成CSV文件就像假脱机一样简单。要将输出写入Excel文件，您需要以编程方式执行此操作。
您可以使用code开发的以下Anton Scheffer：

要求最低的方法是通过某些预定作业将表数据插入某个临时表
create table myexportable as (select sysdate exportdate, q.* from mytable q)
RESP。
insert into myexportable (select sysdate exportdate, q.* from mytable q)
然后使用SQL Plus
导出该数据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;
并且至少将管道分隔的文本文件导入excel。
