I couldn't figure out how to delete a dynamic hook until now b/c it doesn't
appear to be documented but here's how to do it:
*Given the following class with a dynamic hook onBeforeUpdate:*
create class A extends V,OTriggered
alter class A custom onBeforeUpdate=somefunction
select customFields from (select expand(classes) from metadata:schema) where
name="A"
+----+------------------------------+
|# |customFields |
+----+------------------------------+
|0 |{onBeforeUpdate=somefunction} |
+----+------------------------------+
*To delete the the dynamic hook:*
alter class A custom onBeforeUpdate=null
select customFields from (select expand(classes) from metadata:schema) where
name="A"
+----+
|# |
+----+
|0 |
+----+
I really think that dynamic hooks should be stored in normal classes
instead of in metadata:schema... maybe a class called ODynamicHook... so
that they can be managed using regular select, update, insert statements.
For now, please document the way to delete the dynamic hook.
