//1注册驱动
//加载类时,会调用静态代码块,进行驱动注册:DriverManager.registerDriver(driver);
Class.forName("com.mysql.jdbc.Driver");


//2获得连接
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/shujukuName");


//3创建st
Statement st = conn.createStatement();

//4书写sql

String sql = "INSERT INTO 't_user' VALUES (NULL,'jerry',16)";

//5执行sql
st.execute(sql);
//execult()返回boolean值可继续判断获取结果集等  execultUpdate()返回boolean值影响的行数  execultQuery()返回查询到的结果集

//6关闭资源
st.close();
conn.close();
