o_totalprice DECIMAL(13,2) NOT NULL,
o_orderdate DATE FORMAT 'yyyy-mm-dd' NOT NULL,
o_orderpriority CHARACTER(21),
o_clerk CHARACTER(16),
o_shippriority INTEGER,
o_comment VARCHAR(79))
PRIMARY INDEX orders_PI (o_orderkey)
PARTITION BY RANGE_N(o_orderdate BETWEEN DATE '1992-01-01'
AND DATE '1998-12-31'
EACH INTERVAL '1' MONTH)
UNIQUE INDEX (o_orderkey)
INDEX (o_custkey)
INDEX (o_orderdate) ORDER BY VALUES
INDEX (o_orderdate)
INDEX (o_orderdate, o_custkey) ORDER BY VALUES(o_orderdate)
INDEX (o_orderdate, o_orderstatus);
