关于javascript:showspace数据库如何表示

create or replace procedure show_space

(p_segname in varchar2,

p_owner in varchar2 default user,

p_type in varchar2 default ‘TABLE’,

p_partition in varchar2 default NULL )

— this procedure uses authid current user so it can query DBA_*

— views using privileges from a ROLE and so it can be installed

— once per database, instead of once per user that wanted to use it
