amazon-redshiftHow do I create an Amazon Redshift materialized view?
Creating a materialized view in Amazon Redshift requires the following steps:
- Create a view using the
CREATE VIEW
command. This command defines the query that will be used to populate the materialized view. For example:
CREATE VIEW my_view AS
SELECT a, b, c
FROM table1
- Create the materialized view using the
CREATE MATERIALIZED VIEW
command. This command defines the physical storage for the materialized view and the refresh interval. For example:
CREATE MATERIALIZED VIEW my_mview
FROM my_view
REFRESH EVERY 1 DAY
- Refresh the materialized view using the
REFRESH MATERIALIZED VIEW
command. This command will populate the materialized view with the data from the view. For example:
REFRESH MATERIALIZED VIEW my_mview
- To verify the materialized view was created successfully, use the
SELECT
command to query the materialized view. For example:
SELECT * FROM my_mview
