GeneratedValue and composite primary keys?

[Former Member]

Hi all,

just a short question: Can the sequence generators be used for any column, or just for surrogate primary keys?

Imho, the JPA specification a little bit unclear on this point, and I'm not sure how SAP implemented this.

regards,

Christian

Hi Christian,

yes, the JPA spec is unclear in this respect. In SAP JPA, you can use the @GeneratedValues annotation to generated id values only.
