代码如下：
------------------------------------------------------------
import *;
import java.sql.*;

public class Test17 {
    public static String URL="jdbc:mysql://localhost:3306/lll";
    public static String USER="root";
    public static String KEY="1";

    public static void main(String args[]) throws Exception {

        PreparedStatement ps=con.prepareStatement(sql, ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
        ResultSet rs=ps.executeQuery();
        rs.moveToInsertRow();
        File file=new File("C:\\Users\\lll\\Desktop\\JAVA\\long.txt");
        rs.updateString("name", "small_test2");
        rs.updateAsciiStream("note", new FileInputStream(file), file.length());    /*显示这里出错？
