I have Parent Domain and a Child Domain
我有父域和子域
class Parent{
static hasMany = [childs: Child]
}
class Child{
}
In database
Parent_Id Parent_Age Parent_Name
1 20 AAAA
2 25 BBBB
Child_id Child_Age Child_Name Parent_Id(F.K.)
1 2 00000 1
2 6 11111 1
3 5 22222 1
4 3 33333 2
5 4 44444 2
5 9 55555 2
Now I have parent object.
现在我有了父对象。
def parentInstance = Parent.get(1);
def childsList = parentInstance?.childs ---> //from this list here
//i want to get
// only those childs
//whose age is greater
//than or equal to 3.
Or
// greater than or
//equal to 5.
Is it possible to do that on queried list .
是否可以在查询列表中执行此操作。

Try it like this:
试试这样:
Parent parentInstance = Parent.get(1);
List<Child> childList = Child.createCriteria().list(){
parent{
eq("id", 1 as Long)
}
or{
ge("age", 3)
ge("age", 5)
}
}
