WITH LOCAL CHECK OPTION;
mysql> CREATE VIEW v3 AS SELECT * FROM v1 WHERE a > 0
-> WITH CASCADED CHECK OPTION;
Here the v2 and v3 views are defined in terms of another view, v1. v2 has a LOCAL check option, so inserts are tested only against the v2 check. v3 has a CASCADED check option, so inserts are tested not only against its own check, but against those of underlying views. The following statements illustrate these differences:
ql> INSERT INTO v2 VALUES (2);
Query OK, 1 row affected (0.00 sec)
mysql> INSERT INTO v3 VALUES (2);
ERROR 1369 (HY000): CHECK OPTION failed 'test.v3'
The updatability of views may be affected by the value of the updatable_views_with_limit system variable.
