How can I load only the parent object without children objec

I have a Parent object with 2 one-to-many relations like this

Code:

<class name="MyParentClass" table="MyParentTable" dynamic-update="true">
.....
<set name="childOne" inverse="true" >
            <key>
                <column name="PkChildOne"/>
             </key>
            <one-to-many class="ChildOne"/>
  </set>
<set name="childTwo" inverse="true">
            <key>
                <column name="PkChildTwo"/>
             </key>
            <one-to-many class="ChildTwo"/>
  </set>

......

Any time I want load MyParentClass with all children (with session.load(..)), but other time I want load only MyParentClass without all children (maybe with Criteria).

Any solution ?

I will use fetch=join into mapping and HQL for get only parent oject, becouse HQL does't react at fetch=join

set fetch="select" for your collections

if you want to load both collections then execute 2 hql queries:
select parent from Parent parent left fetch join parent.children1
then
select parent from Parent parent left fetch join parent.children2

all this in the same session, your graph will be entirely loaded
