1. 关于视图命名的单复数问题

    动态性能视图(v$xxx)的名字一般都是单数形式，而静态视图(ALL/USER/DBA)一般是复数形式 

    examples: user_tables, user_views

                   v$instance, v$version, v$database, v$session, v$process... 

 

   发现一个特例：v$timezone_names  这个动态视图是个复数形式， 用来查询时区的名字及其缩写形式

   desc v$timezone_names

Name                           Null     Type                                                                                                                                                                                          
------------------------------ -------- --------------------------------------------
TZNAME                                  VARCHAR2(64)                                                                                                                                                                                  
TZABBREV                                VARCHAR2(64)
