学习hibernate时，运行一测试程序时，出现错误 关键信息是the Contents of element type 'Class' must match**** google了一下，猜测是因为测试数据库没有主键。将数据库表加上id int auto_increment primary key后，问题没有出现。暂时不清楚为什么，先记录下。 本文来自ChinaUnix博客，如果查看原文请点：http://blog.chinaunix.net/u/8780/showart_498745.html
从sql server导出的数据，要导出到informix数据库去。。 由于有繁体中文，如果用 “|”做分隔符； 会冲突。所以不能用 “|” .. 。。。 现在写了程序转换成insert语句。。 但表中有 text,byte这两个数据类型。执行insert语句时候出现错误： A blob data type must be supplied within this context 不知道有什么简便的方法来处理。 急！1

用ufsrestore恢复，中途会出现如下提示： You have not read any volumes yet. Unless you know which volume your file(s) are on you should start with the last volume and work towards the first. specify next volume #: 这个是什么意思，我该指定多少？
It's well known that C library like fopen\fwrite\.. only be supported under filesystem, for instance , like fopen function call with at least two arguments , one is path of file like "\usr\xxx\foo.txt", but as for others rtos, nuclues\REX\QNX, in case of running on PDA or mobile phone, there is nerver exist media storage like harddisk , so do they support C library like fopen?
