大家在碰到这样的情况下注意一下！
我正在把基于mysql数据库的程序改为基于sysbase的，可是我的程序在改完之后，执行的时候程序执行结果的页面总是不动（大白页面），刚开始怀疑是mysql的sql语句和sybase的差异造成的，可是经过检查mysql的sql语句没有发现任何的错误（原来的mysql的sql语句已经改动过了），
实在没办法就从程序下手，弄了将近两个小时也没发现程序哪里有毛病。后来把sql语句屏蔽掉能看到相应的页面（但没有数值，因为数值是从数据库中提取出来的）这是怎么回事呢？正在焦头烂额的时候我无意中打开sybase的相应的数据库，突然发现原来在sybase中建设备、数据库的时候采用的是默认的大小2M，一看数据库属性原来数据库已满，原来的大小不能满足使用了，改变大小之后，问题解决，希望大家在碰到类似的问题的时候多想想问题的所在，唉！由于对数据库不了解，结果白白浪费了很多时间，真是郁闷！！:-S
