创建数据库:

CREATE DATABASE `sql_learn_db`;

创建一个表：

Create Table: CREATE TABLE `persons` (
  `Id` int(11) NOT NULL AUTO_INCREMENT,
  `LastName` varchar(255) DEFAULT NULL,
  `FirstName` varchar(255) DEFAULT NULL,
  `Address` varchar(255) DEFAULT NULL,
  `City` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`Id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

+-----------+--------------+------+-----+---------+----------------+
| Field     | Type         | Null | Key | Default | Extra          |
+-----------+--------------+------+-----+---------+----------------+
| Id        | int(11)      | NO   | PRI | NULL    | auto_increment |
| LastName  | varchar(255) | YES  |     | NULL    |                |
| FirstName | varchar(255) | YES  |     | NULL    |                |
| Address   | varchar(255) | YES  |     | NULL    |                |
| City      | varchar(255) | YES  |     | NULL    |                |

DBIndexTest.java:

(请手动修改用户名和密码，并导入驱动包)

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.util.Random;


public class DBIndexTest {

	private static final String MYSQL_DRIVER = "com.mysql.jdbc.Driver";
	private static final String DB_URL = "jdbc:mysql://localhost:3306/sql_learn_db";
	
	private static final String USER_NAME = "root";
	private static final String PASSWORD = "";
	
	private static final String sql = "insert into persons values (null,?,?,'zjut','hangzhou')";
	
	private static Connection conn = null;
	
	private static PreparedStatement pstmt = null;
	
	private static Random random = new Random();
	
	private DBIndexTest(){};
	
	public static String getRandomName() {
		int fornum = 1 + random.nextInt(10);  /* 1~10 */
		StringBuilder sb = new StringBuilder();  /* 97~122 */
		for(int i=0; i<fornum;i++) {
			sb.append((char)(97 + random.nextInt(26)));
		}
		return sb.toString();
	}
	
	private static void createConnection() {
		try {
			Class.forName(MYSQL_DRIVER);
			conn = DriverManager.getConnection(DB_URL,USER_NAME,PASSWORD);
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();

		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();

		}
		
	}
	
	public static Connection getConnection() {
		if(conn == null) {
			createConnection();
		}
		return conn;
	}
	public static void insertRecord() {
		conn = getConnection();
		try {
			if(pstmt == null)
				pstmt = conn.prepareStatement(sql);
			
			pstmt.setString(1, getRandomName());
			pstmt.setString(2, getRandomName());
			int affect = pstmt.executeUpdate();
			System.out.println(affect == 1 ? "插入成功!" : "插入失败!");
			
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	
	public static void main(String[] args) {
		long start = System.currentTimeMillis();
		
		for(int i=0; i< 1000000; i++) {
			insertRecord();
		}
		long end = System.currentTimeMillis();
		
		System.out.println("一共用时:" + (end-start)/1000.0 + "s");
		
	}

}

运行结果：

插入成功!
插入成功!
