ORACLE 查看用户密码修改时间

前几天在给客户培训过程中，有一客户问到能否查看某一用户的密码修改时间，这样可以减少很多不必要的纠纷，大致研究了一下。
1。当前数据库版本为

SQL> select * from v$version;

BANNER
----------------------------------------------------------------
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - Prod
PL/SQL Release 10.2.0.4.0 - Production
CORE    10.2.0.4.0      Production
TNS for Linux: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production

2。查看user$表

SQL> desc user$
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 USER#                                     NOT NULL NUMBER
 NAME                                      NOT NULL VARCHAR2(30)
 TYPE#                                     NOT NULL NUMBER
 PASSWORD                                           VARCHAR2(30)
 DATATS#                                   NOT NULL NUMBER
 TEMPTS#                                   NOT NULL NUMBER
 CTIME                                     NOT NULL DATE
 PTIME                                              DATE
 EXPTIME                                            DATE
 LTIME                                              DATE
 RESOURCE$                                 NOT NULL NUMBER
 AUDIT$                                             VARCHAR2(38)
 DEFROLE                                   NOT NULL NUMBER
 DEFGRP#                                            NUMBER
 DEFGRP_SEQ#                                        NUMBER
 ASTATUS                                   NOT NULL NUMBER
 LCOUNT                                    NOT NULL NUMBER
 DEFSCHCLASS                                        VARCHAR2(30)
 EXT_USERNAME                                       VARCHAR2(4000)
 SPARE1                                             NUMBER
 SPARE2                                             NUMBER
 SPARE3                                             NUMBER
 SPARE4                                             VARCHAR2(1000)
 SPARE5                                             VARCHAR2(1000)
 SPARE6                                             DATE

3。查看某一用户的上一次密码修改时间

SQL> alter session set nls_date_format='yyyy-mm-dd hh24:mi:ss';

Session altered.

SQL> select PTIME from user$ where name='TEST';

PTIME
-------------------
2009-06-15 14:25:31

SQL> !date
Mon Jun 15 18:20:58 EDT 2009

4.修改test用户密码，可以看到test密码修改时间已经改变

SQL> alter user test identified by test;

User altered.

SQL> select PTIME from user$ where name='TEST';

PTIME
-------------------
2009-06-15 18:21:34

SQL> !date
Mon Jun 15 18:21:44 EDT 2009

普通用户也能查看user$表吗？

只要赋普通用户相关权限即可

引用

SQL> grant select on user$ to zhoul;

Grant succeeded.
SQL> conn zhoul/zhoul
Connected
SQL> desc sys.user$;
