ALTER VIEW

Documentation for the ALTER VIEW statement, which is used to modify an existing view's definition without dropping and recreating it.

Syntax

ALTER
    [ALGORITHM = {UNDEFINED | MERGE | TEMPTABLE}]
    [DEFINER = { user | CURRENT_USER }]
    [SQL SECURITY { DEFINER | INVOKER }]
    VIEW view_name [(column_list)]
    AS select_statement
    [WITH [CASCADED | LOCAL] CHECK OPTION]

Description

This statement changes the definition of a view, which must exist. The syntax is similar to that for CREATE VIEW and the effect is the same as for CREATE OR REPLACE VIEW if the view exists. This statement requires the CREATE VIEW and DROP privileges for the view, and some privilege for each column referred to in the SELECT statement. ALTER VIEW is allowed only to the definer or users with the SUPER privilege.

Example

ALTER VIEW v AS SELECT a, a*3 AS a2 FROM t;
