NHibernate 2.1和Oracle 10g客户端出错

Question

我需要让NHibernate 2.1与oracle数据库通信.我被要求使用Oracle 10g客户端.尝试构建会话工厂时出现以下错误:

无法将类型为"Oracle.DataAccess.Client.OracleConnection"的对象强制转换为"System.Data.Common.DbConnection".

我不记得NHibernate 2.01出现此错误.我试图让服务器管理员安装11g客户端,但看起来这是一场失败的战斗.

以下是我的web.config中的重要部分:

<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <qualifyAssembly partialName="Oracle.DataAccess" fullName="Oracle.DataAccess, Version=10.2.0.100, Culture=Neutral, PublicKeyToken=89b483f429c47342"/>    
  </assemblyBinding>
</runtime>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
 <session-factory>
   <property name="dialect">NHibernate.Dialect.Oracle10gDialect</property>
   <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
   <property name="connection.driver_class">NHibernate.Driver.OracleDataClientDriver</property>
   <property name="connection.connection_string_name">Demo</property>
   <property name="show_sql">false</property>
   <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
  </session-factory>
</hibernate-configuration>

Answer 1

我在NHUsers小组问了同样的问题,得到了一个可以接受的答案.将以下内容添加到hibernate配置中:

<property name="hbm2ddl.keywords">none</property>
