Creates or replaces a view on a set of tables or views or both.

REPLACE VIEW redefines an existing view or, if the specified view does not exist, creates a new view with the specified name. Privileges that were granted directly on the original view are retained for the replace view definition.

CREATE/REPLACE VIEW and CREATE/REPLACE RECURSIVE VIEW (see CREATE RECURSIVE VIEW and REPLACE RECURSIVE VIEW) share most of the same code and are variations of each other, but are documented separately for clarity.
See the following sections:

ANSI Compliance

CREATE VIEW is ANSI SQL:2011-compliant.

REPLACE VIEW is a Teradata extension to the ANSI SQL:2011 standard.
