Can any one validate the below queries related to temp tablespace

Question

For Temporary Tablespace Free and Used Space Information, I am using the following query
SELECT fs.tablespace_name tspace,
sum(fs.bytes)/(1024*1024) tot_ts_size_MB,
sum(df.bytes_free)/(1024*1024) free_ts_size_MB,
sum(df.bytes_used)/(1024*1024) used_ts_size_MB
FROM dba_temp_files fs,
(select tablespace_name, bytes_free, bytes_used from v$temp_space_header) df
WHERE fs.tablespace_name(+) = df.tablespace_name
GROUP BY fs.tablespace_name;
For getting how much space is being used by current users, I am using the following query
SELECT b.tablespace tablespace_name,
a.sid sid,
a.username username,
(b.blocks * c.value)/(1024*1024) Current_Usage
FROM v$session a, v$sort_usage b,
(select value from v$parameter where name = 'db_block_size') c
WHERE a.saddr = b.session_addr;
Can any one validate, that above queries are right or not?

Hi,
1.for first query i think u can also use only v$temp_Space_header to find out
the required details by
SELECT tablespace_name, SUM(bytes_used)/1024/1024 "Tot Used Space in MB",
SUM(bytes_free)/1024/1024 "Tot Free Space in MB"
FROM V$temp_space_header
GROUP BY tablespace_name;
