PostgreSQL – How to Drop a Materialized View

ByAdmin

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.
