【中文标题】使用正则表达式语句在休眠中使用 createSQLQuery 获取计数（*）【英文标题】：getting count(*) using createSQLQuery in hibernate with regular expression statement 【发布时间】：2012-10-02 23:34:39 【问题描述】：我正在尝试使用 hibernate 3.2.5 计算列数
创建SQLQuery，
因为我使用了where语句，
使用正则表达式（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"),
)
public class Orders implements Serializable

我该如何解决这个错误？
【问题讨论】：
请显示错误的完整、准确的文本，包括回溯。 啊，您正在使用俄语系统，因此您翻译了错误消息，这就是您说“类似”的原因。有道理，感谢您这样做，值得一提的是那种事情。 来自psql 的'\dt orders` 呢？ id 列肯定存在吗？数据库中可以是大写字母（"ID" 或“Id”）吗？另外，您使用的是什么 JDBC 驱动版本和 PostgreSQL 版本？
所有列都存在于数据库中，还有“id”。jdbc驱动程序是“postgresql-9.0-801.jdbc3”。 PostgreSQL 版本是“1.16.0”。但我认为问题不在于 jdbc 驱动程序或 PostgreSQL，因为查询为“select * from ipony.orders where entryuser_id = :idUser and lastname ~* '^(John)$'”工作正常，但如果我使用类似"select name , login from ipony.orders where entryuser_id = :idUser and lastname ~* '^(John)$'" 它返回相同的错误，即使我添加了列 id，它也需要其他未使用的列.
1.16.0 不是 PostgreSQL 版本。 “select version()”是什么意思？
【参考方案1】：
.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)$'")
.setInteger("idUser", idUser)
.uniqueResult()).longValue();
请注意，此查询的结果可能是Long以外的某个数字类型的值，在这种情况下您需要添加一个转换，如上所示。
【讨论】：
感谢您的回答！另外你能回答为什么像@Override public List<Orders> listOrder(Integer idUser, Integer pageSize, Integer pageNumber,String search) return sessionFactory.getCurrentSession() .createSQLQuery("select name,login from ipony.orders where entryuser_id = :idUser and lastname ~* '^(John)$'").addEntity(Orders.class) .setInteger("idUser", idUser) .setFirstResult(pageNumber) .setMaxResults(pageSize).list(); 这样的查询返回相同的错误
@Zhandos：同样的原因，你只返回实体的两列，而不是全部：Hibernate 将尝试从结果集中加载实体中声明的每个属性。
@Zhandos：您可以写select Orders.* from ... 让Hibernate 自动放入所有必需的列。【参考方案2】：
我也遇到了同样的问题，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)$'
【讨论】：
您的答案晚了大约 12 个月 - 无论如何，不同之处在于count(*) 将在应用任何 where 子句后返回表的完整记录数，而 count(anyField) 不会在该字段中包含 null 值。
同意，虽然我个人认为 ipony.id 是主键（唯一，而不是 null），因此无论如何不能在计数中包含 null 值。以上是关于使用正则表达式语句在休眠中使用 createSQLQuery 获取计数（*）的主要内容，如果未能解决你的问题，请参考以下文章
