如何在休眠5中执行以下查询?
select * form product where name like "%s%" or sku like "%s%"
到目前为止,我正在使用以下代码,但无法正常工作。
searchText = "%" + searchText + "%";
// Search the text.
try {
// Get the record with the username.
SessionFactory sessionFactory = HibernateUtility.getSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
CriteriaBuilder criteriaBuilder = session.getCriteriaBuilder();
CriteriaQuery<ProductsEntity> criteriaQuery = criteriaBuilder.createQuery(ProductsEntity.class);
Root<ProductsEntity> root = criteriaQuery.from(ProductsEntity.class);
Predicate[] predicates = new Predicate[2];
predicates[0] = criteriaBuilder.like(root.get(ProductsEntity_.name), searchText);
predicates[1] = criteriaBuilder.like(root.get(ProductsEntity_.sku), searchText);
criteriaQuery.select(root).where(criteriaBuilder.or(predicates));
Query<ProductsEntity> query = session.createQuery(criteriaQuery);
List<ProductsEntity> productsEntityList = query.getResultList();
productsEntityObservableList.setAll(productsEntityList);
// Set the product table view to the observable list.
tvProductsList.getItems().clear();
tvProductsList.getItems().addAll(productsEntityObservableList);
} catch (HibernateException e ){
WindowsUtility.displayAlert("Database Error", "Unable to connect to database", Alert.AlertType.ERROR);
e.printStackTrace();
}
发生以下错误:

答案 0 :(得分:1)
select * from test
where date > '%0:01%'
在jpql和hql中都是有效的关键字,因此您可以轻松地在like
中或以任何其他方式使用它。示例:
@Query
