分析:使用SQLServer 数据库时,可能发生此异常,原因是微软自己的jdbc驱动不支持同一个记录的字段的重复读取,因为微软加入了text,image这种类型的支持,就限制了字段的回读功能.原因是如果该表存在TEXT, NTEXT, IMAGE等大型字段,对于ResultSet的字段读取必须按照从左向右读,如果你用:
int a = rs.getInt(2);
int b = rs.getInt(1);
则报错。Microsoft给出的方案是不能从右往左也不能连续读2次。
解决方法:这个是微软JDBC驱动的一个bug,我们也可以不用他的驱动,自己到网上下载jtds.jar驱动,使用这种驱动就不会出现上面的异常了.
