Daniel Jimenez commented on ANN-598:
------------------------------------
+1 from me as well.
All of our users from the "users" table have FKs to a few other tables. In most
cases if the row in the other table is deleted we obviously would not want the whole user
deleted, instead just that field set to null. As an example, you would not want a user
deleted just because their default checking account was deleted in another table. Instead
you'd rather set their default checking account to null, because they may have a
savings account, CD, money market, etc.
I quickly looked over the source for the OnDelete and OnDeleteAction annotations, which
led me to AnnotationBinder. Having never looked at any of the Hibernate source before, I
very quickly got overwhelmed.

Add ON clause to @ForeignKey
----------------------------
Key: ANN-598
URL:
http://opensource.atlassian.com/projects/hibernate/browse/ANN-598
Project: Hibernate Annotations
Issue Type: New Feature
Components: binder
Reporter: Christian Bauer
More important than it sounds:
@org.hibernate.annotations.ForeignKey(name = "FK_FEED_DIRECTORY_ID")
I need ON CASCADE DELETE on many of my foreign keys, so I have to do this right now via:
<hibernate-mapping>
<database-object>
<create>
alter table FEED drop constraint FK_FEED_DIRECTORY_ID;
alter table FEED add constraint FK_FEED_DIRECTORY_ID foreign key
(DIRECTORY_ID) references NODE on delete cascade;
</create>
<drop></drop>
</database-object>
</hibernate-mapping>
This is a bit annoying, especially since @JoinColumn(columnDefinition) is also not an
option - I don't want to hardcode my HSQL datatypes.
So we should accept a parameter on @ForeignKey (I know that the Hibernate binder
doesn't have that notion at all, we need it in native Hibernate as well) that accepts
"[ON {DELETE | UPDATE} {CASCADE | SET DEFAULT | SET NULL}];" and does the right
thing during schema export.
