I am just find out if there is a limit to the number of foreign keys (FK) that can be listed in a mappings file?

I am using my MySQL and wanted to know if there is a limit.

I had made a mistake putting PK in the first post...

I still don't understand what you want to do, but the answer is probably "no, there is no limit".

sorry - too much coffee

also, if i wanted to have a mapping for a document archive hibernate is able to understand primary, secondary and tertiary keys?

Code:

table doc_archive

PK docID
PK action
PK date

...

is this possible?

Thanks,

Jason

I don't know what a "tertiary" or "secondary" key is. What you show is a composite primary key. Yes, Hibernate can handle composite primary keys.
