服务器上执行exp成功了，我很自然的说了句，是客户端的问题，然后和测试说，可以端重新装下再试试看(因为他装了两个客户端，我是怀疑变量等原因导致)。当他装好后，然后和我说，还是不行，我开始怀疑是版本的问题，然后对比了下今天他的报错，和数据库版本，发现果真是两边版本的问题(数据库服务器版本:9.2.0.4，客户端版本:10.2.0.1)，解决问题，让他装一个低版本的客户端，再装个高版本的客户端，然后在根据导出数据的版本，选择不同版本的exp。

3.失误总结
自己的自以为是让他忙碌了几个小时，深表歉意。人家把你当做专家，你就应该对人家负责任。用认真的心态去帮别人解决问题，不要以为自己就要离开，用种不负责任的态度去处理事情，更不要以为这些东西，自己已经很懂了，不认真对待。
