DB2 Date Partitioning Guide
In DB2, table partitions can be created by date using the following steps:
- To begin with, create a partitioned table specifying the partition key as the date field. For example, you can use the following statement to create a table partitioned by date:
CREATE TABLE my_table (
id INTEGER,
date_column DATE
)
PARTITION BY RANGE (date_column) (
STARTING '2022-01-01' ENDING '2022-12-31' EVERY 1 DAY
)
- Next, you can use the ALTER TABLE statement to add a partition. For example, the following statement will add a partition named “2022_01”:
ALTER TABLE my_table ADD PARTITION '2022_01' STARTING '2022-01-01' ENDING '2022-01-31'
- Additional partitions can be added as needed to store data partitioned by date.
Please note that using a date as a partition key can help optimize query performance and make data easier to manage and maintain.
