查询超时了 --------------------编程问答-------------------- 请问怎么解决啊之前都是挺好的 --------------------编程问答-------------------- 嗯，是查询超时了，或者是连接数据库超时了，有可能是你的网络有问题 --------------------编程问答-------------------- http://topic.csdn.net/u/20091120/17/1c1d994a-e2bd-48c3-b04e-58de64e11558.html --------------------编程问答-------------------- 是否网络连接数据库的网络有问题或者说数据量比较大你执行查询的时候超出了默认的允许时间你加上try{}catch(){}可以看捕获的异常自己加断点调试。 --------------------编程问答-------------------- 新手不知道怎么弄啊 --------------------编程问答-------------------- 检查你的sql语句，检查你的数据读取方法。 --------------------编程问答-------------------- 看看，你登录的时候，是否与后台进行了正常的通信，检查你的连接语句
