Easily:
conn / as sysdba
CREATE TABLESPACE part1
DATAFILE 'c:\temp\part01.dbf' SIZE 50M
BLOCKSIZE 8192
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K
SEGMENT SPACE MANAGEMENT AUTO
ONLINE;
CREATE TABLESPACE part2
DATAFILE 'c:\temp\part02.dbf' SIZE 50M
BLOCKSIZE 8192
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K
SEGMENT SPACE MANAGEMENT AUTO
ONLINE;
CREATE TABLESPACE part3
DATAFILE 'c:\temp\part03.dbf' SIZE 50M
BLOCKSIZE 8192
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K
SEGMENT SPACE MANAGEMENT AUTO
ONLINE;
ALTER USER uwclass QUOTA UNLIMITED ON part1;
ALTER USER uwclass QUOTA UNLIMITED ON part2;
ALTER USER uwclass QUOTA UNLIMITED ON part3;
conn uwclass/uwclass
CREATE TABLE hash_part (
prof_history_id  NUMBER(10),
person_id        NUMBER(10) NOT NULL,
organization_id  NUMBER(10) NOT NULL,
record_date      DATE NOT NULL,
prof_hist_comments VARCHAR2(2000))
PARTITION BY HASH (prof_history_id)
PARTITIONS 3
STORE IN (part1, part2, part3);
CREATE TABLE duplicate_hash_part
PARTITION BY HASH (prof_history_id)
PARTITIONS 3
STORE IN (part1, part2, part3) AS
SELECT * FROM hash_part;Follow the same logic for list and range partitions
