包中的专业知识实体

    <?xml version="1.0" encoding="utf-8" ?>

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Nortonrose.DataAccess" namespace="Nortonrose.DataAccess.Mappings">

  <class name="Nortonrose.DataAccess.SearchEntities.ExpertiseEntity" table="v_ExpertiseTitle" lazy="true">

        <id name="RxId">

          <column name="rx_id"/>


          <generator class="native" />

        </id>

        <property name="ExpertiseTitle">

            <column name="title"/>

        </property>

    </class>



</hibernate-mapping>

专业知识表具有用户ID，专业知识ID，并映射到专业知识标题。这一切都在一个视图中完成。
