Thanks Diego. Indeed, I was surprised that the join properties corresponding at
foreign keys are automatically generated in the mapping file with a InnoDB
database but not with MyISAM.
Now I know why :-)
Cheers.

Objet : Re: [d2rq-dev] Difference between InnoDB and MyISAM database engine
Hello Julien
There aren't foreign key constrains in myisam. I think you can add the
constraint to the table definition, but it won't work.

Hi,
Maybe it’s a weak question but I still attempt :-)
Why with a InnoDB database engine the foreign keys are automatically generated,
and when it’s a MyISAM database engine, they are not ?
Cheers.
