Re: [eclipselink-users] DB-generated values as properties on JPA-entity

[Tom Ware <tom.ware@xxxxxxxxxx>]

Hi Andreas,

  As James mentions, using the current functionality set, your best best is to use a refresh.

  As for PostGres, you are right, our PostGreSQLPlatform has should be able to take advantage of the equivalent feature in PostGres.

Hi all.

 

I'm having the same issue as this guy: http://www.eclipse.org/forums/index.php/t/368890/

 

I'm having fields in my @Entity which are generated by the DB as insert-time and I need to map them.

 

In Hibernate it's possible using it's @Generated annotation:

@Column(name = "id", nullable = false, unique = true, updatable = false, insertable = false)
@org.hibernate.annotations.Generated(org.hibernate.annotations.GenerationTime.INSERT)
var activityId: java.lang.Long = null

Does EL has something similar?

 

BTW: The blog-post mentions Oracle is the only supported platform supporting the "returning ..." syntax in SQL INSERT/UPDATE. PostgreSQL supports this too.

 

Thanks.
