我在使用 Hibernate 4.1 和 MySQL 5 将 Folder 实体保存到数据库时遇到了我在下面添加的错误。我对其他实体没有任何问题。

You have an error in your SQL syntax; check the manual that corresponds to your mysql server version for the right syntax

这是我的文件夹表：

CREATE TABLE `folder` (
  `folder_id` int(11) NOT NULL AUTO_INCREMENT,
  `folder_name` varchar(45) COLLATE utf8_turkish_ci NOT NULL,
  `order` int(11) DEFAULT NULL,
  PRIMARY KEY (`folder_id`)
) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COLLATE=utf8_turkish_ci$$

我的文件夹实体：

    @Entity
    @Table(name = "folder")
    public class Folder implements Serializable
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "folder_id", nullable = false, insertable = true, updatable = true, length = 10, precision = 0)
    private int folderId;
    @Column(name = "folder_name", nullable = false, insertable = true, updatable = true, length = 65535, precision = 0)
    private String folderName;
    @Column(name = "order", nullable = true, insertable = true, updatable = true, length = 10, precision = 0)
    private int order;

public int getFolderId() 
    return folderId;


public void setFolderId(int folderId) 
    this.folderId = folderId;


public String getFolderName() 
    return folderName;


public void setFolderName(String folderName) 
    this.folderName = folderName;


public int getOrder() 
    return order;


public void setOrder(int order) 
    this.order = order;

Hibernate 生成的插入语句：

insert into folder (folder_name, order) values (?, ?)

【问题讨论】：

是的。它需要反引号或不同的列名 【参考方案1】：

我认为问题在于 ORDER 是 MySQL 保留字。

要执行 INSERT 语句，您需要将该列名包含在反引号中，如下所示：

insert into folder (folder_name, `order`) values (?, ?)

【讨论】：

没错，但这是一个 Hibernate 问题，而不是 SQL 问题。是的，似乎使用保留关键字会导致此问题，在我的情况下，我将 Spring-data JPA 与 MySQL 一起使用，并且在我的一个表中，我使用“desc”来保存描述，但这是一个MySQL 保留关键字，我得到了同样的错误，将列名更改为“描述”解决了错误。【参考方案2】：

好的，我找到了解决方案；我们仍然可以使用 'order' 关键字作为列名，如下所示：

@Column(name = "`order`", length = 10, precision =0) 
private int order;

感谢 Ghost 和 Dave Newton 的关心。问候..

【讨论】：

谢谢；我对表“组”有同样的问题。（很奇怪，因为 phpmyadmin 和 mysql 工作台都没有阻止我做这样的事情）。获取关键字列表，请参阅dev.mysql.com/doc/refman/5.6/en/reserved-words.html 也感谢您的贡献.. @BrendanRius 节省我的时间@talha6 谢谢。为我工作！
