我正在尝试使用休眠 3.2.5 计算列

创建 SQL 查询，

因为我使用 where 语句，

它使用正则表达式（它在 HQL 中不起作用）。

数据库是 Postgre。

这是我的查询：

@Override
public Long CountFilterListOrder(Integer idUser) {


    return (Long)sessionFactory.getCurrentSession()
            .createSQLQuery("select COUNT(*) from ipony.orders where entryuser_id = :idUser and lastname ~* '^(John)$'")
                            .addEntity(Orders.class)
            .setInteger("idUser", idUser)
            .uniqueResult();
}

我的实体：

@Entity
@Table(name = "orders")
@NamedQueries({
@NamedQuery(name = "Orders.findAll", query = "SELECT o FROM Orders o"),

 })

.addEntity(Orders.class)告诉 Hibernate 将查询结果转换为实体。这显然是错误的，因为您的查询返回标量值而不是实体。所以，你需要摆脱它：

return ((Number) sessionFactory.getCurrentSession()
         .createSQLQuery("select COUNT(*) from ipony.orders where entryuser_id = :idUser and lastname ~* '^(John)$'") 
         .setInteger("idUser", idUser)
         .uniqueResult()).longValue();

请注意，此查询的结果可能是除 之外的某个数字类型的值Long，在这种情况下，您需要添加一个转换，如上所示。

它发生在我身上也是一样的，是查询，问题是 SQL 计数（*），改用这个（例如）：

SELECT COUNT(ipony.id) from ipony.orders where entryuser_id = :idUser and lastname ~* '^(John)$'
