To incorporate the PARTITION feature into a TABLE creation command in Hive, you can add the PARTITIONED BY clause to the CREATE TABLE statement followed by the partition columns.
For example:
CREATE TABLE my_table (
id INT,
name STRING
)
PARTITIONED BY (year INT, month INT, day INT)
This creates a table "my_table" with two regular columns "id" and "name" and three partition columns "year", "month", and "day". Data can be inserted into the partitions using the following syntax:
INSERT INTO TABLE my_table PARTITION (year=2021, month=10, day=15)
VALUES (1, 'John'),
(2, 'Doe')
This inserts two rows into the partition year=2021/month=10/day=15. Additional partitions can be created dynamically using the ALTER TABLE ADD PARTITION command.
