ALTER [ALGORITHM = {UNDEFINED | MERGE | TEMPTABLE}] [DEFINER = {user
| CURRENT_USER }] [SQL SECURITY { DEFINER | INVOKER }] VIEWview_name
[(column_list
)] ASselect_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 12.1.20, “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. As of MySQL
5.1.23, ALTER VIEW
is allowed only
to the definer or users with the
SUPER
privilege.
