  • Summary:

    In the UML to rdbms transformation code given in section A.2.3 :

    – mapping to update a Table with new columns of foreign keys
    mapping Association::asso2table() : Table
    when

    {self.isPersistent();}

    {
    init

    {result := self.destination.resolveone(Table);}

    foreignKey := self.map asso2ForeignKey();
    column := result.foreignKey->column ;
    }

    The mapping asso2table is supposed to update a table by adding new columns, but with the last line of the mapping, the existing columns are all replaced by the new ones. I suggest to replace the last line with :
    column += result.foreignKey->column ;
