批处理Batch && PreparedStatement :

import java.sql.*;

public class TestBatch {

    public static void main(String[] args) throws ClassNotFoundException, SQLException

    {

        Connection conn = DriverManager.getConnection

        ("jdbc:mysql://localhost/test","root","ZHEN");

        /*

        Statement stmt = conn.createStatement();  //执行静态 SQL 语句并返回它所生成结果的对象。

        stmt.addBatch("INSERT INTO student VALUES(30,'ddd',12,'ii')");

        stmt.addBatch("INSERT INTO student VALUES(31,'ddd',12,'ii')");

        stmt.addBatch("INSERT INTO student VALUES(32,'ddd',12,'ii')");

        stmt.addBatch("INSERT INTO student VALUES(33,'ddd',12,'ii')");

        stmt.executeBatch();

        stmt.close();

        */

        PreparedStatement pstmt =

            conn.prepareStatement("INSERT INTO student VALUES(?,?,?,?)");

        pstmt.setInt(1, 40);
