First off, your examples lack either the "/" or ";" to execute the statement.

Your first query runs just fine?

select
( select sum(bytes)/1024/1024/1024 data_size from dba_data_files ) +
( select nvl(sum(bytes),0)/1024/1024/1024 temp_size from dba_temp_files ) +
( select sum(bytes)/1024/1024/1024 redo_size from sys.v_$log ) +
( select sum(BLOCK_SIZE*FILE_SIZE_BLKS)/1024/1024/1024 controlfile_size from v$controlfile) "Size in GB"
from
dual;

I get a size back in GB that matches the DB I tried it on.

Note that Gerwin used in line 8, "dual;" whereas you had "dual".

2nd one runs also, same result.

How are you running this query and what error do you get?

Ahhh -- look at line 5, you have split the word "from" with a carriage return.  Copy and paste Gerwin's example, or else run your code through a text editor to proof for punctuation.

Tony, a side comment since I don't have email access.  You are asking a slew of great, new questions this week.  Would you please take time to go back through them, and close the issues by awarding points.  Guidelines on doing so are available with a help query.

Regards,
dvz
