nhibernate从DB查询缓存查询的各行

Question

我是一个缓存的查询，如下所示。

IQuery query = session.GetISession().CreateQuery(
            @"from Table1 as ant
              inner join fetch ant.Table2 Table2
              left join fetch ant.Collection1 -- this is self join to table1
              where ant.ExpDate is null
              order by TAble2.DispOrder, ant.Col1, ant.Col2");

        query.SetCacheable(true).SetCacheRegion("region1");                 
        return query.List<Table1>()

在web.config文件中设置缓存

<class-cache class="Table1" usage="nonstrict-read-write" region="Region1" />
<collection-cache collection="Table1.Collection1" usage="nonstrict-read-write" region="Region1" />

我在生成的日志中注意到，正如预期的那样，上面的查询执行了sql。但是，之后会为每个表和每一行单独执行sql（这是随机发生的）。

单个sql如下

select .... from table1 where id=1
select .... from table1 where id=2..... for all the unique ids of table1
select .... from table2 where id=1..... for all the unique ids of table2
and also for the left join

我不是为什么每个唯一ID都有查询的原因。
