Two entities with link oneToone

Support
#1

Hi,
I have two entities with link oneToOne. In the first entity there is a code, and in the second one there is its description. I need to link the description in the first entity.
In the first Entity “Art” I have the field with a code, and I create another field “pdc”, which represented the Entity with description, of type COMPOSITION.

In the “Pdc” Entity, instead, I have create another field “art” of type ASSOCIATION.

At runtime, the system give me a
SQLServerException: The column’s name ‘ART_CODICE_ARTICOLO’ is not valid.
But I never declared this column/attribute!
If I declare this entity, the second one “PDC” as Owning side, I can insert the column name, so which column name I have to insert in?
Can you help me, please?

Hi, @infonuvola2015.

But I never declared this column/attribute!

I think this column(ART_CODICE_ARTICOLO) belongs to the attribute art of Pdc entity.
In Pdc entity should be roughly the following attribute:

@OneToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "ART_CODICE_ARTICOLO")
protected Art art;

Can you attach source files for Art and Pdc entities?
Entity Pdc also imported?
What is the column SQL type for ART.CODICE_ARTICOLO, PDC.ART_CODICE_ARTICOLO and PDC.ID?
