Spring hibarnate error: ошибка при выполнении DDL через оператор JDBC

Question

Spring hibarnate error: ошибка при выполнении DDL через оператор JDBC

0

Мне действительно нужна помощь, которую я искал во всех вопросах, которые я нашел в StackOverflow, и ничего не работает или не отвечает на мои вопросы. Я никогда раньше не использовал спящий режим, и я не знаю, что я делаю неправильно. Я создал таблицы, но со вставками у меня проблемы.

есть 3 таблицы с именем пользователя и записью. примечание и пользователь работают без проблем, но когда я создаю роль с тем же методом, она дает эту ошибку:

org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement

код, все еще создающий пользователя и примечание, но не создавший роль

пользователь:

@Entity
@Table(name="user")
public class User {
    @Id
    @Column(unique = true)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    @NotEmpty
    private String username;
    @Email
    @Column(unique = true)
    @NotEmpty
    private String email;
    private int age;
    @Size(min = 4)
    private String password;
    @ManyToOne
    @JoinColumn(name="ROLE_ID")
    private Role role;
    @OneToMany(mappedBy="user", cascade=CascadeType.ALL)
    private List<Note> notes;

примечание (дающая ошибку):

@Entity
@Table(name="role")
public class Role {

    @Id
    @Column(unique = true)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    private String name;
    //perms
    private int user;
    private int msg;
    private int com;
    private int cTop;
    private String modCap;
    private int mod;
    private int supermod;
    private int editmsg;
    private int editcom;
    private int edittopic;
    private int edituser;
    private int adminpanel;
    private int admin;
    //users
    @OneToMany(mappedBy="role", cascade=CascadeType.ALL)
    private List<User> users;

примечание для работы exp:

@Entity
@Table(name="note")
public class Note {

    @Id
    @Column(unique = true)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    private String date;
    private String type;
    private String title;
    private String message;
    @ManyToOne
    @JoinColumn(name="USER_ID")
    private User user;

Вызвано: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: у вас есть ошибка в синтаксисе SQL; проверьте руководство, соответствующее версии сервера MariaDB, для правильного синтаксиса для использования рядом с " целое целое целое", но не null, mod_cap varchar (255), msg integer not null, name varchar (2 'в строке 1

mod - это имя функции. Вы не можете использовать его, не ускользая от него. Измените это имя переменной и оно будет работать.

В качестве альтернативы вы можете поместить это в свою конфигурацию для автоматического удаления всех идентификаторов:

hibernate.globally_quoted_identifiers=true

@ArtunBurakMecik Вы можете добавить spring.jpa.properties.hibernate.globally_quoted_identifiers=true в свой файл application.properties .
