在用MyEclipse和SQLSERVER2008做一个简单的增删改查的时候，数据写不到数据库里去怎么回事？
提示的错误是：
com.microsoft.sqlserver.jdbc.SQLServerException: 索引 7 超出范围。

------解决方案--------------------
你看下有多少列，你现在超出了。
------解决方案--------------------
给的值超出了数据库的列数，对照一下，很容易就能找到
------解决方案--------------------
你的com.dao.UserDao.Saveuser(UserDao.java:79)79行有问题，建议你写这种DAO的时候用下junit测试下
