Temporary tablespaces:

SELECT a.tablespace_name, a.BYTES total, a.bytes - nvl(b.bytes, 0) free

FROM (SELECT tablespace_name, SUM (bytes) bytes FROM dba_temp_files GROUP BY tablespace_name) a,

(SELECT tablespace_name, SUM (bytes_cached) bytes FROM v$temp_extent_pool GROUP BY tablespace_name) b

WHERE a.tablespace_name = b.tablespace_name(+)

or

select TABLESPACE_NAME, BYTES_USED/1024/1024 used_MB,BYTES_FREE/1024/1024 free_MB

from V$TEMP_SPACE_HEADER;

A typical table space can be used as follows:

Select a.Tablespace_Name, a.Total || 'M' Total_Space, (a.Total - b.Free) || 'M' Used_Space, To_Char((a.Total - b.Free) / a.Total * 100, '99.99') || '%' Pct_Free

From

(Select Tablespace_Name, Sum(Bytes) / 1024 / 1024 Total From Dba_Data_Files Group By tablespace_Name) a,

(Select Tablespace_Name, Sum(Bytes) / 1024 / 1024 Free From Dba_Free_Space Group By Tablespace_Name) b where a.Tablespace_Name = b.Tablespace_Name;
