简单好用！ JAVA JDBC 连接 MYSQL

package com.hy.action;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class Analysis {
public static void main(String args[]) {
Connection con = null;
try {
// 获得MySQL驱动的实例
Class.forName("com.mysql.jdbc.Driver").newInstance();
// 提供地址用户名密码并获得连接对象
con = DriverManager.getConnection("jdbc:mysql://192.168.1.113/h","root", "root");

if (!con.isClosed())
// 连接成功提示
System.out.println("Successfully connected to MySQL server using TCP/IP...");
// 有Connection对象创建Statement
Statement st = con.createStatement();
// 运行SQL语句读取
ResultSet rs = st.executeQuery("SELECT * FROM Ption");
// 循环读取数据
while (rs.next()) {
// 打印数据
System.out.println(rs.getString("ID"));
}
// 关闭
con.close();
} catch(Exception e) {
System.err.println("Exception: " + e.getMessage());
}
}
}

注，如果有子查询的，就不用用Statement

            String sql = "SELECT SysVersion FROM P_ClientInformation where ID =(select max(ID) from P_ClientInformation)";            PreparedStatement pst = con.prepareStatement(sql);            ResultSet rs2 = pst.executeQuery();             // 循环读取数据            while (rs2.next()) {                // 取出数据库最新版本号
