MySQL 8.4 Release Notes
15.1.11 更改视图语句
ALTER
[ALGORITHM = {UNDEFINED | MERGE | TEMPTABLE}]
[DEFINER = user]
[SQL SECURITY { DEFINER | INVOKER }]
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
see Section 15.1.23, “CREATE VIEW Statement”). 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 permitted only to the definer or users with the SET_ANY_DEFINER
or ALLOW_NONEXISTENT_DEFINER
privilege.
