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) "percent_used"

(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) b
