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

y')  AND owner='用户名' and object_type='TABLE';

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

查询某个时间之后创建的表有哪些：

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

4','dd-mm-yy')  AND owner='用户名';

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

查询当前用户下某个表的创建时间：

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

' AND owner='用户名';

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

连接oracle并执行文件，并将执行结果保存到log文件中：

C:\Users\admin>sqlplus用户名/密码@ORCL @D:\aaa.sql > d:\sqlout.log;

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

执行bat文件完成上面的任务：

@echo off

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

@echo Create End!

pause

将以上代码保存到bat类型的文件中，并执行

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

注意：用oracle数据库创建的用户名替换上面内容中的‘用户名’三个字，密码同理。
