Java数据库MySQL

Question

嗨,在下面的代码中,它只打印表中的第一个id和第一个名称.如何让它打印出查询中的所有结果而不仅仅是第一批结果？谢谢

Statement stat = conn.createStatement();  

stat.execute("CREATE TABLE Test (Id VARCHAR(20), Name VARCHAR(20))");  
stat.execute("INSERT INTO Test VALUES ('1AA', 'John')");  
stat.execute("INSERT INTO Test VALUES ('2AA', 'George')");
stat.execute("INSERT INTO Test VALUES ('3AA', 'Richard')");


ResultSet result = stat.executeQuery("SELECT * FROM Test");  
result.next();  
System.out.println(result.getString("Name"));  
System.out.println(result.getString("Id"));
stat.execute("DROP TABLE Test");

使用while循环迭代所有结果:

...
ResultSet result = stat.executeQuery("SELECT * FROM Test");  
while(result.next()) {  
    System.out.println(result.getString("Name"));  
    System.out.println(result.getString("Id"));
}
stat.execute("DROP TABLE Test");
