Issue 15917: bug in the uml to rdbms transformation example (qvt-rtf)
Source:  (, )
Nature: Clarification
Severity: Minor
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 ;
Resolution: yes
Revised Text: In A.2.3 mapping Association::asso2table() change
column := result.foreignKey->column ;
to
column += result.foreignKey->column ;
