Hi,

Class Bar subclass Foo, using the composite key formed with idPart1 & idPart2:

create table Foo (
idPart1 INT,
idPart2 INT,
desc VARCHAR);

create table Bar (
idPart1 INT,
idPart2 INT,
someValue VARCHAR);

How can I map this ? The does not mention the use of composite keys
for joined subclasses

thx

Something like that I guess

Code:

<joined-subclass ...>
   <key>   <!-- a collection inherits the composite key type -->
      <column name="idPart1"/>
      <column name="idPart2"/>
    </key>
