我知道这种类型的问题以前曾被问过，但我对hibernate相当陌生，而且我很难理解这种情况。所以即时通讯在Hibernate中使用这个@formula，这是类：@ManyToOne映射有什么关系呢？为什么Hibernate抛出的子查询返回多个值？
所以我有一个实体类是这样的：
@Entity
@Table(name = "ABC")
public class ABC{
@Id
@Column(name ="ID")
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Access(AccessType.PROPERTY)
private Long id;
@Column(name="AMOUNT")
private Double amount
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "R_ID")
@Getter
@Setter
private TXY txy;
@Formula((SELECT (abc.AMOUNT + (abc.AMOUNT * ISNULL(tx.RATE,0))) FROM ABC abc left join TXY tx on abc.R_ID = tx.ORIGINAL_R_ID WHERE abc.ID = ID)")
@Getter
private Double taxAmount;
}
该子查询返回多个值：
SELECT (abc.AMOUNT + (abc.AMOUNT * ISNULL(tx.RATE,0)))
FROM ABC abc
left join TXY tx on abc.R_ID = tx.ORIGINAL_R_ID
WHERE abc.ID = ID
我得到以下错误：
java.sql.SQLException: Subquery returned more than 1 value. This is illegal when the subquery follows =, !=, <, <= , >, >=, or when the subquery is used as an expression.

我将不胜感激任何帮助和建议。
错误很明显：您的公式查询返回多个值。如果我们知道你的数据，可能会给出一个替代查询。 –
@TimBiegeleisen这就是当我在一个硬编码的Id例如'在哪里invc.ID = 7777'运行这个查询。它只给我一个结果。 '@ ManyToOne'在这里扮演一个角色吗？ – zachandcode
如果即使一个查询返回2个或更多值，它也会失败。您的测试只显示它通过了某个发票，而不一定是所有发票。 –
