Query to retrieve from partitioned table

Question

i have a table called xyz which is having 5 columns
(client,datmonth,productid,productname,productdesc)
and it is partitioned as
column client is the primary partition
column datamonth is subpartitioned based on client
if i have to select both client and datamonth how to do it by select query
i arrived till
select * from xyz partition <clientid-partition>
but unable to proceed further
any help?

Answer 1

Like that ?
DROP TABLE XYZ ;
CREATE TABLE XYZ
( client_No NUMBER(10) Not Null check (CLIENT_NO > 0)
, datmonth DATE Not Null
PARTITION BY RANGE( client_No )
SUBPARTITION BY LIST (datmonth)
SUBPARTITION TEMPLATE
( SUBPARTITION SP_2005 VALUES (To_Date('20050101','YYYYMMDD'))
, SUBPARTITION SP_2006 VALUES (To_Date('20060101','YYYYMMDD'))
, SUBPARTITION SP_2007 VALUES (To_Date('20070101','YYYYMMDD'))
, SUBPARTITION SP_DEFAULT VALUES (DEFAULT)
( PARTITION P_0001 VALUES LESS THAN (2)
, PARTITION P_0002 VALUES LESS THAN (3)
, PARTITION P_0003 VALUES LESS THAN (4)
, PARTITION P_0004 VALUES LESS THAN (5)
, PARTITION P_Others VALUES LESS THAN (MAXVALUE)
INSERT INTO XYZ
SELECT Mod( RowNum,6)+1 Client_No
, Add_Months( Trunc( SysDate, 'YYYY') , Mod( DBMS_RANDOM.random, 24)) DateMOnth
FROM DUAL CONNECT BY ROWNUM <= 100
SELECT * FROM XYZ PARTITION (P_0001) A;
SELECT * FROM XYZ SUBPARTITION (P_0001_SP_2006) A;
SELECT * FROM XYZ SUBPARTITION (P_0002_SP_2006) A;
