当属性存在时，org.hibernate.Query无法解析属性[Hibernate JPA]

我想加载吸烟者并且被诊断出心跳高于120的患者。我一直得到这个错误org.hibernate.Query无法解决吸烟问题。如果我改变了其他东西的属性f.e.我得到了同样的错误。我尝试了不同的查询，结果相同。所有实体都在单独的文件中。我的代码出了什么问题？

查询：

Query q = em.createQuery("select p from Patient p join p.visits v join v.data d WHERE d.smoking　= 'yes' and d.heartrate > 120");

代码：

import javax.persistence.Query;
[...]

@Entity
public class Patient extends Person implements Serializable {
     private static final long serialVersionUID = 1L;
     private int id;
     @OneToMany
     private List<Visit> visits = new ArrayList<>();
[...]
}
@Entity
public class Visit implements Serializable {
     private static final long serialVersionUID = 1L;
     private int id;
     @OneToOne
     private Data data;
[...]
}
@Entity
public class Data implements Serializable {
     private static final long serialVersionUID = 1L;
     private int id;
     private String smoking;
     private int heartrate;
[...]
}

请注意，您的查询包含U+3000 IDEOGRAPHIC SPACE而不是常规空格：

... WHERE wy.palacy　= 'tak' AND wy.tetno > 120
                   ^ here

Hibernate将其视为属性名称的一部分。
