JAVA-JDBC向数据库插入文件错误java.sql.SQLException: Incorrect string value: '\xB4\

这是我的数据库建表代码：
CREATE TABLE userclob(
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(30) NOT NULL,
note LONGTEXT
) ;

JAVA code :

import java.sql.Connection ;
import java.sql.DriverManager ;
import java.io.File ;
import java.io.FileInputStream ;
import java.io.InputStream ;
import java.sql.PreparedStatement ;

public class ClobDemo{
//MySQL-JDBC驱动
public static final String DBRIVER = "org.gjt.mm.mysql.Driver" ;
//MySQL数据库连接地址
public static final String DBURL = "jdbc:mysql://localhost:3306/mldn" ;
//MySQL 用户名
public static final String DBUSER = "root" ;
//MySQL 密码
public static final String DBPASSWORD = "mysqladmin" ;
public static void main(String args[]) throws Exception{
Connection conn = null ;
PreparedStatement prs = null ;
String sql = "INSERT INTO userclob(name,note) VALUES (?,?) " ;
Class.forName(DBRIVER) ; //加载JDBC驱动
//实例化Connection对象获得与数据库连接
conn = DriverManager.getConnection(DBURL,DBUSER,DBPASSWORD) ;
//实例化PreparedStatement对象
prs = conn.prepareStatement(sql) ; //使用预处理写入SQL语句
String name = "罗星笔记";
//用输入流读取文件
File f = new File("d:" + File.separator + "sql.txt") ;
InputStream input = null ;
input = new FileInputStream(f) ;
prs.setString(1,name) ;
prs.setAsciiStream(2,input) ;
prs.executeUpdate() ; //执行更新操作
input.close() ; //关闭输入流
conn.close() ; //关闭数据库
}
}

抛错：

检查下数据库表的字符格式
show full columns from userclob;
如果不是GBK，可用下面方法修改
alter table userclob modify note varchar(30) character set gbk;
