例：
SQL> create table donny(id char(1024));
表已创建。
SQL> set serveroutput on
SQL> exec show_space('DONNY')
Free Blocks.............................0
Total Blocks............................5
Total Bytes.............................40960
Unused Blocks...........................4
Unused Bytes............................32768
Last Used Ext FileId....................8
Last Used Ext BlockId...................27
Last Used Block.........................1
