hi gurus,

any body have any idea of how to join these querries. i want to select from two different tables namely dba_data_files call it A and dba_free_space call it B. but the columns being selected are same i.e. tablespace_name and bytes from both tables.

i want to select in a single querry as..

tablespace_name        bytes1        bytes2


--                                --                --

--                                --                --

--                                --                --

where bytes1 is sum(bytes) group by tablespace_name in table a. and bytes2 is sum(bytes) group by tablespace_name in table b.
