[求助]访问数据库报错，不知道什么原因，请指点……

用的是tomcat和Sqlserver；

不知道是什么地方没有配置好能还是什么其它原因！thx

db url中加上selectMode=cursor

我加上试试好像还是不行，报错信息一样的，我把我的配置代码也贴上，劳烦你们看看

hibernate.properties：

## MS SQL Server

hibernate.dialect net.sf.hibernate.dialect.SQLServerDialect
hibernate.connection.username sa
hibernate.connection.password 123456

## Microsoft Driver (not recommended!);
hibernate.connection.driver_class com.microsoft.jdbc.sqlserver.SQLServerDriver
hibernate.connection.url jdbc:microsoft:sqlserver://egov-server:1433;DatabaseName=test;SelectMethod=test

hibernate.cfg.xml:

<!DOCTYPE hibernate-configuration
    PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">

        <!-- Mapping files -->
        <mapping resource="study/hibernate/Course.hbm.xml"/>

    </session-factory>

</hibernate-configuration>

不知道是否是因为我的配置文件写的有问题，还是什么，我实在看不出来了

？？

先谢谢你的关注！
SelectMethod=×××我不太清楚这个有什么用？
另外我修改成你先前所说的selectMode=cursor，但好像问题依旧，现在搞的很郁闷。

sorry，是SelectMethod=cursor

OK!好了，原来是这个原因阿，再问一句SelectMethod=cursor
是什么意思，起什么作用的

向数据库表中insert一条记录时候，tomcat报出一下信息，并insert没有成功，不知为何？

这几个warn是什么意思呢？
请指教。thx！
