如何解决“您的SQL语法有误；请检查与您的MySQL服务器版本相对应的手册，以获取正确的语法错误” Hibernate 4 [duplicate]

好，我找到了解决方案；我们仍然可以像这样使用’ ‘关键字作为列名：

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

感谢 和 的关心。问候..

解决方法

使用 Hibernate 4.1 和 MySQL 5 将 Folder实体保存到数据库时，出现以下错误。我没有其他实体的任何问题。

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",length = 65535,precision = 0)
    private String folderName;
    @Column(name = "order",nullable = true,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insert语句：

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

hibernate设置：

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource"><ref local="dataSource"/></property>
        <property name="packagesToScan" value="tr.edu.aibu.dms.model" />
        <property name="hibernateProperties">
            <props>

                <prop key="hibernate.c3p0.min_size">2</prop>
                <prop key="hibernate.c3p0.max_size">50</prop>
                <prop key="hibernate.c3p0.maxPoolSize">50</prop>
                <prop key="hibernate.c3p0.minPoolSize">2</prop>
                <prop key="hibernate.c3p0.initialPoolSize">2</prop>
                <prop key="hibernate.c3p0.timeout">300</prop>
                <prop key="hibernate.c3p0.max_statements">50</prop>                
            </props>
        </property>
    </bean>
