The following ALTER TABLE request modifies the tables orders and orders_cp created in Table Definitions for Examples. The outcome of the requests are identical to the table alterations performed in later ALTER TABLE requests in this example, but using different syntax.
The request is valid if there are no rows with values for o_orderdate between January 1, 1992 (DATE ‘1992-01-01’) and December 31, 1992 (DATE ‘1992-12-31’).
ALTER TABLE orders MODIFY DROP RANGE BETWEEN DATE '1992-01-01' AND DATE '1992-12-31' ADD RANGE BETWEEN DATE '1999-01-01' AND DATE '2000-12-31' EACH INTERVAL '1' MONTH;
The following request modifies the partitioning for the column-partitioned table orders_cp.
ALTER TABLE orders_cp MODIFY DROP RANGE BETWEEN DATE '1992-01-01' AND DATE '1992-12-31' ADD RANGE BETWEEN DATE '1999-01-01' AND DATE '2000-12-31' EACH INTERVAL '1' MONTH;
The following ALTER TABLE request modifies the table created in Table Definitions for Examples. The result is equivalent to the outcome of other requests in this example set using different syntax, and is valid if there are no rows with values for o_orderdate between January 1 1992 (DATE ‘1992-01-01’) and December 31 1992 (DATE ‘1992-12-31’).
ALTER TABLE orders MODIFY DROP RANGE WHERE PARTITION BETWEEN 1 AND 12 ADD RANGE BETWEEN DATE '1999-01-01' AND DATE '2000-12-31' EACH INTERVAL '1' MONTH;
The following request modifies the partitioning for the column-partitioned table orders_cp.
ALTER TABLE orders_cp MODIFY DROP RANGE BETWEEN DATE '1992-01-01' AND DATE '1992-12-31' ADD RANGE BETWEEN DATE '1999-01-01' AND DATE '2000-12-31' EACH INTERVAL '1' MONTH;
The following ALTER TABLE request modifies the table created in Table Definitions for Examples. The result is equivalent to the outcome of other requests in this example set and is valid if there are no rows with values for o_orderdate between January 1 1992 (DATE ‘1992-01-01’) and December 31 1992 (DATE ‘1992-12-31’).
ALTER TABLE orders MODIFY DROP RANGE WHERE Orders.PARTITION IN (1,2,3,4,5,6,7,8,9,10,11,12) ADD RANGE BETWEEN DATE '1999-01-01' AND DATE '2000-12-31' EACH INTERVAL '1' MONTH;
The following request modifies the partitioning for the column-partitioned table orders_cp.
ALTER TABLE orders_cp MODIFY DROP RANGE BETWEEN DATE '1992-01-01' AND DATE '1992-12-31' EACH INTERVAL '1' MONTH ADD RANGE BETWEEN DATE '1999-01-01' AND DATE '2000-12-31' EACH INTERVAL '1' MONTH;
