VIEW view_name [(column_list)]
AS select_statement
[WITH [CASCADED | LOCAL] CHECK OPTION]
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. See Section 12.1.16, “CREATE VIEW Syntax”. 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.
