问题描述
在使用 Hibernate 4.1 &将文件夹实体保存到数据库中时，出现以下错误: MySQL 5 .我没有其他实体的任何问题.
I'm getting the error I added below while saving Folder entities into database using Hibernate 4.1 & MySQL 5. I don't have any problems with other entitites.
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;
}
}
休眠生成的插入语句:
insert into folder (folder_name, order) values (?, ?)
休眠设置:

推荐答案
好，我找到了解决方案；我们仍然可以像这样将" order "关键字用作列名:
OK I've found solution; we still can use 'order' keyword as column name like this:
@Column(name = "`order`", length = 10, precision =0)
private int order;
