> Q. You need to determine the amount of space currently used in each

> You can retrieve this information in a single SQL statment using only one

> DBA view.

> A.DBA_EXTENTS.
>
> B.DBA_SEGMENTS.
>
> C.DBA_DATA_FILES.
>
> D.DBA_TABLESPACES.

> I was thinking that dba_extents and dba_segments would be the correct
answer

> select tablespace_name, sum(bytes) from dba_extents group by
tablespace_name
> ;
>
> select tablespace_name, sum(bytes) from dba_segments group by
> tablespace_name;
>
>
>
> But The answer given says dba_extents and dba_data_files. Is the given
> answer wrong or is there some way of finding out from dba_data_files how
> much space is used up in a tablespace
>
> For that matter what does the question want to know ? does it want to know
> how much space do the tablespaces have ( that would be the sum of the
sizes
> of the data files ) or how much is ""used up"" ?
