HQL和原生SQL(native SQL)查詢要通過為org.hibernate.Query的實例來表達。 這個接口提供了參數(shù)綁定、結果集處理以及運行實際查詢的方法。 你總是可以通過當前Session獲取一個Query對象：

List cats = session.createQuery(
"from Cat as cat where cat.birthdate < ?")
.setDate(0, date)
.list();
List mothers = session.createQuery(
"select mother from Cat as cat join cat.mother as mother where cat.name = ?")
.setString(0, name)
.list();
List kittens = session.createQuery(
"from Cat as cat where cat.mother = ?")
.setEntity(0, pk)
.list();
Cat mother = (Cat) session.createQuery(
"select cat.mother from Cat as cat where cat = ?")
.setEntity(0, izi)
.uniqueResult();]]
Query mothersWithKittens = (Cat) session.createQuery(
"select mother from Cat as mother left join fetch mother.kittens");
Set uniqueMothers = new HashSet(mothersWithKittens.list());
