Re: sql question

Guys,

The code I use looks a lot like this, i.e the two subqueries, but I found I needed an outer join,

where a.tablespace_name = b.tablespace_name(+)

otherwise tablespaces with no free space rows in dba_free_space (i.e. completely full ones) don't get reported correctly.

Regards,
Terry.
