Is @PrimaryKeyJoinColumn(...) the same as...? [message #639749]

Hello,

using @PrimaryKeyJoinColumn, which doesn't have the insertable and updatable parameters:

Is @PrimaryKeyJoinColumn interchangable with

@JoinColumn(..., insertable = false, insertable = false)

or

@JoinColumn(..., insertable = true, insertable = true)

?

What are the insertable and updatable properties set to? Are they set to anything at all?

Are they interchangable at all? I'm getting rather inconsistent mapping exception with EclipseLink and Hibernate. Is @PrimaryKeyJoinColumn reserved for inheritance and secondary tables?

Yes.

Equivalent to the first one. Also see

http://stackoverflow.com/questions/4205628/jpa-is-primarykey joincolumn-the-same-as-joincolumn-insertable-u

EclipseLink has problems with exchanging @PrimaryKeyJoinColumn(...) and @JoinColumn(..., insertable = false, updatable = false). I'll post a link to a bug report and a standalone JavaSE, HSQLDB, Ant example soon.

James, thanks again for helping on this.

Thanks
Karsten
