关于李兴华《Java开发实战经典》一些问题

第17章 Java数据库编程

1  最新Mysql数据库连接格式应改为

public static final String DBDRIVER = "com.mysql.cj.jdbc.Driver";
public static final String DBURL= "jdbc:mysql://localhost:3306/mldn?serverTimezone=UTC";

2  628页书上本来Sql语句为

String sql = "SELECT id,name,password,age,sex,birthday" +"FROM user";

 会出现  Exception in thread "main" java.sql.SQLSyntaxErrorException: Unknown column 'id' in 'field list'

 所以改为

String sql = "SELECT id,name,password,age,sex,birthday FROM user";
