    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)
