Hi,
I am a newbie and having trouble writing a query to join 3 unrelated classes ClassA, ClassB, ClassC.
Here are the details (and I will show in code below).. ClassA has long attribute that will match the id of ClassB (but the id of ClassB is
Long). ClassB has attribute of type ClassC. ClassC has attribute of type string.
Here is the code:
Code:
public class ClassA {
....
long classBid;
....
}
public class ClassB {
....
Long id;
ClassC classC;
....
}
public class ClassC {
String name;
}
here are the hbm relevant lines:
ClassA hbm:
Code:
<property name="classBid" not-null="true" column="CBID">
ClassB hbm:
Code:
<many-to-one not-null="false" column="CLASS_C" name="classC">
ClassC hbm:
Code:
<property name="name" not-null="true" column="NAME">
I want to get all objects of ClassA where ClassA.classBid=ClassB.id and ClassB.classC=ClassC and ClassC.name="abc"
Thanks,
John
