在navicat上执行select * from stubase where 学号='J0401'语句正确，但用myeclipse执行却出现以上结果，哪位大虾能帮忙解答一下啊，万分感激啊
------解决方案--------------------
我之前看过一个帖子，数据库的字段名称用中文，然后我又发现你这个帖子字段用中文，十分蛋疼
你还是换成英文吧，你这个错误就是字段“学号”乱码导致的
------解决方案--------------------
真牛，字段中用中文
------解决方案--------------------
------解决方案--------------------
??='J0333'' 数据库中字段“学号”乱码了变成“？？”了，你改成英文的字段就ok了
------解决方案--------------------
MYSQL的字段恐怕不支持中文吧，这个恐怕在SQL编程里面没有吧
