Question

我正在尝试使用后端Postgres运行应用程序。它工作得很好，但是当我改变Dialect to Oracle应用程序工作正常但只是按顺序下降时，它正在尝试运行Postgres Query。

域名

@Column(name = "person_id", nullable = false)
    @GeneratedValue(generator = "person_seq", strategy=GenerationType.SEQUENCE)
    @SequenceGenerator(name = "person_seq", sequenceName = "person_seq", allocationSize = 1)
    private Long id;

    @Column(name = "title_id")
    private Integer titleId;
    @Column(name = "surname")
    private String surname;
    @Column(name = "forename")
    private String forename;
    @Column(name = "person_name_suffix")
    private String personNameSuffix;
    @ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.PERSIST)
    @JoinColumn(name = "user_id", nullable = true)
