Hello all,
I'm trying to convert the following SQL query to HQL and am not sure if it is totally possible:
Code:
select * from PARTY as p
left join object_association as oa
on p.party_id = oa.associated_object_id
left join party as p1
on oa.master_object_id = p1.party_id
where p.name_human_first = 'Brian' and
p1.organization_name = 'RTE';
Party is a table that hold instances of both Humans and Organizations discriminated by an object_type_id. An instance of Human is "associated" with an Organization through a table called object_associations which represents a many-to-many between instances of Party. It is mapped as a "bag" in the mapping file from 2 perspectives - what the parent object is and what the child object is. Any two object types in the system may be "related" through this table, hence each object has a set of "associations" which represents those objects of which it is a child and a set of "associatedObject" which represents those objects for which it is the parent. Each of these sets contain instances of ObjectAssociation, which in turn has a "master object" and "associated object." In the case of Human -> Organization, the Organization is the master object and the Human is the associated object. A row then exists in object_association with a master_object_id = to the party_id of the Organization and an associated_obejct_id = to the party_id of the Human. Also, each instance of an ObjectAssociation has an object_type_id which relates to an type_object table - it is essentially a way of saying what the nature of the relationship is between 2 objects (e.g. "Employed By"). I want to be able to find, for example, all the Humans whose first name = "Brian" that are associated with an Organiztion whose name = "RTE" (and also with an object_type.typeName = "Employed By". The SQL query works as expeccted - it returns a unique result. The HQL I've come up with has become more difficult however as it returns a Cartesian Product of all people named "Brian" along with an instance of the Organization whose name is "RTE"
Code:
from org.wgbh.scape.domain.Human as p,
org.wgbh.scape.domain.Organization as p1
left join p.associations
left join p1.associatedObjects
where p.firstName = 'Brian' and
p1.name = 'RTE';
The problem, of course, is the "any" mapping between an ObjectAssociation instance and its other objects. They can represent any object in the system so at any given moment, the master_object could be Human, Organization or Fruity Pebbles and so could the associatedObject. I can mitigate this in the interface because I know what is being searched for from a particular search page (for exmaple, there is a specific human search page with a field for Company Name and First Name). But I'm not sure how Hibernate handles the relationship between bags and any and if they are searchable in this way. I've also tried the Criteria API using the following:
Code:
Example exampleAssociation = Example.create( query.getAssociation() ).ignoreCase();//.enableLike( MatchMode.ANYWHERE );
Example exampleObject = query.fromMaster()
? Example.create( query.getMasterObject() ).ignoreCase().enableLike( MatchMode.ANYWHERE )
: Example.create( query.getAssociatedObject() ).ignoreCase().enableLike( MatchMode.ANYWHERE );
Criteria crit = session.createCriteria( query.getQueryClass() ).add( exampleObject ).createCriteria( query.fromMaster() ? "associatedObjects" : "associations" ).add( exampleAssociation );
logger.debug( "Criteria class = " + crit.getCriteriaClass() );
return new UFOSet( crit.list() );
The API use generates the following SQL:
Code:

Hope this makes sense.. thanks for sticking with the post to the end and thanks for any ideas, assistance or suggestions (even those of the "Why the @!#$ are you doing it this way?" type. I'm beginning to think I may need to make some significant changes.)
