手机什么东西能够运行mysql
在今天的移动设备市场中,人们离不开手机。随着移动互联网的发展,手机能够完成越来越多的任务,甚至可以运行一些数据库软件,如MySQL。
MySQL是一种流行的开源关系型数据库管理系统,它广泛应用于网站和应用程序的背后。作为一种功能强大的关系型数据库软件,MySQL不仅可运行在PC和服务器上,还可以在移动设备上运行。
public class MySQLDemo { private Connection connect = null; private Statement statement = null; private ResultSet resultSet = null; final private String host = "localhost"; final private String user = "root"; final private String password = "root"; final private String database = "test_db"; public void readDataBase() throws Exception { try { Class.forName("com.mysql.jdbc.Driver"); connect = DriverManager.getConnection("jdbc:mysql://" + host + "/" + database, user, password); statement = connect.createStatement(); resultSet = statement.executeQuery("SELECT * FROM users"); while (resultSet.next()) { String name = resultSet.getString("name"); String email = resultSet.getString("email"); System.out.println("Name: " + name); System.out.println("Email: " + email); } } catch (Exception e) { throw e; } finally { close(); } } private void close() { try { if (resultSet != null) { resultSet.close(); } if (statement != null) { statement.close(); } if (connect != null) { connect.close(); } } catch (Exception e) { } } }
