查看oracle的版本信息(两种方法)

以前查oracle的版本信息，只知道一种方法，就是用v$versions视图，如下：

SQL> select * from v$version;

BANNER
----------------------------------------------------------------
Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production
PL/SQL Release 9.2.0.1.0 - Production
CORE 9.2.0.1.0 Production
TNS for 32-bit Windows: Version 9.2.0.1.0 - Production
NLSRTL Version 9.2.0.1.0 - Production

今天在http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96521/dba.htm#13306上又学到一种方法:query the data dictionary view

PRODUCT_COMPONENT_VERSION,

如下：

SQL> col product format a35
SQL> col version format a15
SQL> col status format a15
SQL> select * from PRODUCT_COMPONENT_VERSION;

PRODUCT 　　　 VERSION STATUS
----------------------------------- 　　　--------------- ---------------
NLSRTL 　　　9.2.0.1.0 Production
Oracle9i Enterprise Edition 9.2.0.1.0 Production
PL/SQL 　　　 9.2.0.1.0 Production
TNS for 32-bit Windows: 9.2.0.1.0 Production
