JDBC访问数据库的基本步骤

摘要: --> 载入JDBC驱动程序
--> 定义连接的URL
--> 建立连接
--> 创建Statement对象
--> 执行sql语句（增删改查）
--> 结果处理
--> 关闭连接

Class.forName(com.mysql.jdbc.Driver);

String url = "jdbc:mysql://localhost:3306/getConn";

Connection connection = DriverManager.getConnection(url, "SqlUserName", "SqlPassword");

Statement statement = connection.createStatement();

ResultSet resultset = statement.excuteQuery(sql);

while(resultset.next()) {}

close(resultset);

close(statement);

close(connection);
