PostgreSQL – How to Drop a Materialized View
You can drop (delete) a materialized view using the DROP MATERIALIZED VIEW
statement in PostgreSQL database. Here’s the basic syntax:
DROP MATERIALIZED VIEW IF EXISTS view_name;
where
view_name
is the name of the materialized view you want to drop.IF EXISTS
(optional) clause ensures that PostgreSQL will not raise an error if the materialized view doesn’t exist. If the materialized view exists, it will be dropped; if it doesn’t exist, no error will be raised.
Here’s an example of dropping a materialized view named total_sales_by_product
:
DROP MATERIALIZED VIEW IF EXISTS total_sales_by_product;
Make sure you exercise caution when using the DROP
statement, as it permanently removes the materialized view and its data.
