Hyunsik Choi updated TAJO-285:
------------------------------

    Attachment: TAJO-285.patch

I've attached the first patch. This patch adds RANGE, LIST, HASH, and COLUMN partition options to CREATE TABLE statement. COLUMN partition type is for Hive-style partition. 

Each partition type's example is as follows:
{code:title=Hash Partition}
CREATE TABLE sales ( col1 int, col2 int)
PARTITION BY HASH (col1)
PARTITIONS 2;

CREATE TABLE sales ( col1 int, col2 int)
PARTITION BY HASH (col1)
(
  PARTITION part1,
  PARTITION part2,
  PARTITION part3
);
{code}

{code:title=Range Partition}
CREATE TABLE sales ( col1 int, col2 int)
PARTITION BY RANGE (col1)
 (
  PARTITION col1 VALUES LESS THAN (2),
  PARTITION col1 VALUES LESS THAN (5),
  PARTITION col1 VALUES LESS THAN (MAXVALUE)
 );
{code}

{code:title=List Partition}
CREATE TABLE sales ( col1 int, col2 int)
PARTITION BY LIST (col1)
 (
  PARTITION col1 VALUES ('Seoul', '서울'),
  PARTITION col2 VALUES ('Busan', '부산')
 );
{code}

{code:title=List Partition}
CREATE TABLE sales ( col1 int, col2 int)
PARTITION BY LIST (col1)
 (
  PARTITION col1 VALUES ('Seoul', '서울'),
  PARTITION col2 VALUES ('Busan', '부산')
 );
{code}

{code:title=Column Partition (Hive Partition)}
CREATE TABLE sales ( col1 int, col2 int)
PARTITION BY COLUMN (col1, col2, col3);
{code}

> We can refer to Oracle, and MySQL. They have well-defined statements.
