RE: Free space for all tablespaces

Tom:

Try this: It gives freespaces in each datafiles/tablespaces.

select b.file_id,b.tablespace_name "Tablespace Name", b.bytes/(1024*1024) MB, (b.bytes- sum(nvl(a.bytes,0)))/(1024*1024) "MB Used",
sum(nvl(a.bytes,0))/(1024*1024) "MB Free",
(sum(nvl(a.bytes,0))/(b.bytes))*100 "% Free"
from sys.dba_free_space a, sys.dba_data_files b where a.file_id(+) = b.file_id
group by b.tablespace_name,b.file_id, b.bytes order by b.tablespace_name

I just want a SQL query to give me the freespace in all tablespaces. This doesn't work:

select a.tablespace_name, sum(a.bytes) TOTAL_SPACE, sum(b.bytes)a FREE_SPACE from sys.dba_data_files a, sys.dba_free_space b where a.tablespace_name = b.tablespace_name group by 1;

Does anyone have a query that does work??

thanks,
