Trying to find the
best approach to a 1:M relationship.
(Apologize ahead if
I'm missing something)
class master
{
private List children ;
public void setChildren(List
list){}
public List getChildren() {}
}
The suggestions from
the mail archives seem to indicate two possibilities
<sqlMap...
insert into master values(...) ;
<iterate id=children>
insert into Childvalues(..) ;
</iterate>
</sqlMap
or....
Master master = new
Master() ;
Child child = new
Child() ;
master.getChildren().add(child) ;
MasterDAO.save(master)
;
child.setParent(master) ;
ChildDAO.save(child)
;
Using the first
approach causes me to create multiple insert statements for a "Child" insert
(One in the Master mapping, one in the child mapping... Is there a way to define
links to other statements?
Using the second
approach causes me to use "Relational" constructs to describe a Object
mapping.
