关键子串

Question

我遇到了hibernate连接问题。我有两个表，dbo.issues和dbo.comments，其中每个问题可以有多个与之关联的注释。在dbo.issues表中，ID表示为ISSUE-123456，而在注释表中，它们表示为123456，没有ISSUE-前缀。简化代码如下。

Issue.java

@Entity
@Table(name = "dbo.issues")
//And some named queries
public class Issue
{
    @Id
    @Column(name = "CallID")
    private String id;

    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "issue")
    private List<IssueComment> comments;

    //Getters and setters here
}   

IssueComment.java

@Entity
@Table(name = "dbo.comments")

public class IssueComment implements Serializable
{
    @Id
    @Column(name = "issueid")
    private String issueId;

    @Column(name = "comment")
    private String comment;

    @ManyToOne
    @JoinColumnOrFormula(formula=@JoinFormula(value="SUBSTR(CallID, 7, LEN(CallID))"))
    private Issue issue;

    //Getters and setters here

}

当我尝试运行查询时，出现错误：

com.microsoft.sqlserver.jdbc.SQLServerException：列名'issue_CallID'无效。

谁能看到我做错了什么？我只能对表格进行只读访问，因此我无法操纵它们以使我的生活更轻松！
