统一二楼意见
估计又是哪个做作业的,上网搜到代码,运行不了,来求助的哩...

我总觉得授人以鱼不如授人以渔...
可是总有些SB叫嚣着:要么给代码给答案,要么滚蛋...
虽然我知道不要跟SB一般见识,但是我真的没修炼到宠辱不惊...

就是创建文件将其导入之后,再利用查询的功能时不能找到相应的记录

以下是引用G梦在2013-9-6 15:55:21的发言:

就是创建文件将其导入之后,再利用查询的功能时不能找到相应的记录


你这样说还是不够具体的,人家不见到你导入的文件是什么文件(空文件?)
别人不知道你输入了什么,需要查询什么,或者期望结果是什么,这些问题都没有明确,人家看这样的问题也是很郁闷的

你自己下断点调试下咯

导入的是一个知过能改个人信息的文件,包括职工的工号,姓名,所在部门,工资级别,性别等东西; 查找的时候就是按照编号来查询的
