SQL> select COUNT(*) from dba_objects where created< to_date('17-01-14','dd-mm-y

y')? AND owner='用戶名' and object_type='TABLE';

==============================================================

查詢某個時間之后創建的表有哪些：

SQL> select object_name,created from dba_objects where created> to_date('17-01-1

4','dd-mm-yy')? AND owner='用戶名';

================================================

查詢當前用戶下某個表的創建時間：

SQL> select object_name,created from dba_objects where object_name ='DN_EMPLOYEE

' AND owner='用戶名';

==============================================

連接oracle并執行文件，并將執行結果保存到log文件中：

C:\Users\admin>sqlplus用戶名/密碼@ORCL @D:\aaa.sql > d:\sqlout.log;

==============================================

執行bat文件完成上面的任務：

@echo off

sqlplus %connection% @D:\data_carryover\select_table.sql > D:\data_carryover\select_table_log.log

@echo Create End!

pause

將以上代碼保存到bat類型的文件中，并執行

================================

注意：用oracle數據庫創建的用戶名替換上面內容中的‘用戶名’三個字，密碼同理。
