Nhibernate 如何在NH3.2中使用多对多关系实现.ChildWhere（）映射

我有以下FNH映射：

public class ItemMap : ClassMap<Item>
{
   public ItemMap ()
   {
       this.HasManyToMany(a => a.ChildItems).ChildWhere("IsDeleted = 0").AsSet();
   }
}

public class ItemMap : ClassMap<Item>
{
   public ItemMap ()
   {
      this.HasManyToMany(a => a.ChildItems).Where("IsDeleted = 0").AsSet();
   }
}

使用

的hbm文件的结果。其中（“IsDeleted=0”）

为：

<hibernate-mapping>
  <class name="Item" table="Item">
    <set name="ChildItems" table="ItemsToChildItems">
      ...
      <many-to-many class="ChildItem" where="IsDeleted = 0">
        <column name="ChildItemId" />
      </many-to-many>
    </set>
  </class>
</hibernate-mapping>

<hibernate-mapping>
  <class name="Item" table="Item">
    <set name="ChildItems" table="ItemsToChildItems" where="IsDeleted = 0">
      ...
      <many-to-many class="ChildItem">
        <column name="ChildItemId" />
      </many-to-many>
    </set>
  </class>
</hibernate-mapping>

...

谁有类似的问题或可以提供解决方案？我需要帮助

我也遇到了同样的问题，我找到了解决办法：

分3步解决：

1） 将新接口方法添加到IMANYTOMANYAPPER接口：

公共接口imanytomanyapper:icolumnsapper
{

Where无效（字符串SQLWHERE条款）；
}

2） 在ManyToManyCustomizer类中实现新方法：

public void Where（字符串sqlwhere子句）
{ 
AddCustomizer（propertyPath，（imanytomanyapper x）=>x.Where（sqlwhere子句））；
}

3） 在ManyToManyMapper类中实现新方法：

public void Where（字符串sqlwhere子句）
{ 
manyToMany.where=sqlwhere子句；
}

<hibernate-mapping>
  <class name="Item" table="Item">
    <set name="ChildItems" table="ItemsToChildItems">
      ...
      <many-to-many class="ChildItem" where="IsDeleted = 0">
        <column name="ChildItemId" />
      </many-to-many>
    </set>
  </class>
</hibernate-mapping>

<hibernate-mapping>
  <class name="Item" table="Item">
    <set name="ChildItems" table="ItemsToChildItems" where="IsDeleted = 0">
      ...
      <many-to-many class="ChildItem">
        <column name="ChildItemId" />
      </many-to-many>
    </set>
  </class>
</hibernate-mapping>
