--------------------------------------
Consider this situation, if db only supports CREATE VIEW [IF NOT EXISTS], it
will support ALTER VIEW. Of course, similar to mysql db is to support CREATE OR
REPLACE VIEW and also support ALTER VIEW, thanks.
mysql doc:

{code:java}
CREATE
[OR REPLACE]
[ALGORITHM = {UNDEFINED | MERGE | TEMPTABLE}]
[DEFINER = user]
[SQL SECURITY { DEFINER | INVOKER }]
VIEW view_name [(column_list)]
AS select_statement
[WITH [CASCADED | LOCAL] CHECK OPTION]
{code}
[https://dev.mysql.com/doc/refman/8.0/en/alter-view.html]
