JPA - enum JOIN (JPQL)

Question

我得到了以下JPQL查询：

select cio from CadastralIncomeObjection cio where cio.dateInput < :maxValidInputDate and cio.active = true and cio.reasonInValid.valid = false "
        + "and exists (select dd from DocumentDossier dd join dd.documents d where dd.id = cio.id and d.attachmentType = be.ejb.model.entity.admin.option.REPORT)"

除了枚举的使用之外，一切都是正常的。如果我使用d.anyOtherField = someValue，那么查询就会编译。如果我把(正确的)枚举名称放在那里，它就不会。

映射：

package be.ejb.model.entity.dossier;

@Entity
@Table(name = "DOCUMENT")
public class Document {
    @Column(name = "T_I_TYA", nullable = false)
    @Enumerated(EnumType.STRING)
    private AttachmentType attachmentType;

    /* other fields etc */

}

package be.ejb.model.entity.admin.option;

public enum AttachmentType {
    REPORT;
}

我得到的错误是：

unknown identification variable [be]. The FROM clause of the query does not declare an identification variable [be]

Answer 1

问题解决了..忘记在包声明后包含"AttachmentType“..
