1.查看表空间的名称及大小：
select d.tablespace_name, d.file_id, d.file_name,round(bytes/(1024*1024),0) total_spacefrom dba_data_files dorder by tablespace_name
2.查看表空间使用情况：
select a.tablespace_name,a.bytes/1024/1024 "sum MB",(a.bytes-b.bytes)/1024/1024 "used MB",b.bytes/1024/1024 "free MB",round (((a.bytes-b.bytes)/a.bytes)*100,2) "used%" from(select tablespace_name,sum(bytes) bytes from dba_data_files group by tablespace_name) a,(select tablespace_name,sum(bytes) bytes,max (bytes) largest from dba_free_space group by tablespace_name)bwhere
