Create View

The CREATE VIEW statement defines a new view in the catalog.

Examples​

-- create a simple view
CREATE VIEW v1 AS SELECT * FROM tbl;
-- create a view or replace it if a view with that name already exists
CREATE OR REPLACE VIEW v1 AS SELECT 42;
-- create a view and replace the column names
CREATE VIEW v1(a) AS SELECT 42;

Syntax​

CREATE VIEW defines a view of a query. The view is not physically materialized. Instead, the query is run every time the view is referenced in a query.

CREATE OR REPLACE VIEW is similar, but if a view of the same name already exists, it is replaced.

If a schema name is given then the view is created in the specified schema. Otherwise it is created in the current schema. Temporary views exist in a special schema, so a schema name cannot be given when creating a temporary view. The name of the view must be distinct from the name of any other view or table in the same schema.
