Correct usage of @AttributeOverride on embedded class

Hello chaps,

I am writing some small hibernate examples and the simple @AttributeOverride is 'doing my head in' (as we say in the UK). The code below gives the error
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'boringEntity_boringCode' in 'field list'
and I'm pretty sure this is because I'm using the @AttributeOverride wrong so hibernate is using the default name for the FK reference for BoringEntity, which won't work. Take a look:





And the tables are:

1_CompoundIdEntity2
-someCode
-boringEntityId

1_BoringEntity
-boringCode
-boringDesc

Any help appreciated. I don't find the documentation for this tag particularly revealing I'm afraid.
Cheers,
John

Solved!!

Silly me.. I forgot to add

@JoinColumn(name="boringEntityId")

beside the @OneToOne tag.If you don't put @JoinColumn then HB use the default name which is boringEntity_boringCode. No @AssociationOverride required.

Regards,
John
