我需要知道JoinQueryOver和JoinAlias之间的区别是什么,以及何时使用它们？

谢谢.

我有以下代码

string idName = builder.IdentifierName;
Disjunction disjunction = Restrictions.Disjunction();
IList ids = new ArrayList(entityInfos.Length);
foreach (var entityInfo in entityInfos)
{
    ids.Add(entityInfo .Id);
}
disjunction.Add(Restrictions.In(idName, ids));
criteria.Add(disjunction);
criteria.List();

(我还没写过,它是来自NHibernate.Search的简化代码)

值idName是正确的("Id").

在我的映射中,我没有将Id映射到实体属性,它只是DB:

<id column="Id" type="int">
  <generator class="native" />
</id>

当我运行代码时,它会抛出异常:
