Hi everyone,

I have a simple but delicate problem.

I have an existing database schema created in MS SQL 2000, inherited

from a legacy application (that I'm migrating to Java).

In my JPA entities I used to add some @ManyToOne properties

in order to load some join data (for easy use in JSF data tables).

But Hibernate (certainly not jTDS) always auto generates foreign key

constraints for each such associations when it does not exist physically!!

[size=16]How can I prevent Hibernate from modifying my database schema??[/size]

Thanks,

Hi,

do you mean that Hibernate is modifying your schema at startup? If so check whether you have the property hibernate.hbm2ddl.auto defined in your configuration. If so you should remove it, then your schema won't be modified.

Hi,

What if I want my schema created automatically but I don't need the foreign keys for relations.
Does anybody know how this can be done except specifying in mapping foreign-key="null" ?

Hi,

I don't think you can, but try the Tools forum.
