Oracle Concepts - finding table and index tablespace locations

Oracle Tips by Burleson Consulting

Table and tablespace location

Finding out who owns a table and what tablespace it is in is a pretty common need of the DBA. In this query, we use the dba_tables view to find the owner and tablespace name of the EMP table.

SQL>  select owner, table_name, tablespace_name
  2   from dba_tables
  3  where table_name='EMP';
OWNER                TABLE_NAME           TABLESPACE_NAME
-------------------- -------------------- -------------
SCOTT                EMP                  USERS
POLL                 EMP                  USERS

As we can see from this query, we have two tables called EMP, owned by two different users (Scott and Poll). Both tables are contained in the USERS tablespace.

A good exercise for you might be to try to join this query with a view like DBA_EXTENTS and figure out just how big these tables are allocated.

This is an excerpt from the bestselling "Easy Oracle Jumpstart" by Robert Freeman and Steve Karam (Oracle ACE and Oracle Certified Master).  It?s only $19.95 when you buy it directly from the publisher here.
