Home -> Community -> Usenet -> c.d.o.misc -> Re: Novice question: Tablespaces and Users
Um
See Daniel's answer. The idea behind his approach as I understand it is to partition tables on a client column and to store the partitions in separate areas. This does do exactly as Daniel describes.
It also proves my statement that " A user cannot own multiple objects of the same type with the same name " to be woefully wrong.
I ought to have known this
1 select object_type,count(*) from all_objects
2 where owner='NIALL' and object_name='SALES'
3* group by object_type
SQL> /
OBJECT_TYPE COUNT(*)
------------------ ---------- TABLE 1 TABLE PARTITION 16
