NHibernate的流利組由

我有這樣的nhibernate標準：NHibernate的流利組由

 criteria.Add(Subqueries.PropertyIn("Id", DetachedCriteria.For<ReconItemReconSide>() 
      .SetProjection(Projections.ProjectionList() 
      .Add(Projections.GroupProperty("ReconItemFk")) 
      .Add(Projections.Min("ReconciliationSideFk"))) 
      .Add(Expression.In(Projections.Property("ReconItemFk"), items)) 
      ));

哪位成爲該查詢（I已刪除了部分從外部選擇字段以最小化這裏的長度）：

SELECT this_.Id      as Id8_0_ 
FROM CI.BM_RECONCILIATION_SIDE this_ 
WHERE this_.Id in (SELECT this_0_.BM_RECON_ITEM    as y0_, 
         min(this_0_.BM_RECONCILIATION_SIDE) as y1_ 
       FROM  CI.BM_RECON_ITEM_RECON_SIDE this_0_ 
       WHERE this_0_.BM_RECON_ITEM in (345061 /* :p0 */,345877 /* :p1 */) 
       GROUP BY this_0_.BM_RECON_ITEM)

問題是我想讓inner-select只選擇一個字段（min（this_0_.BM_RECONCILIATION_SIDE）），但groupby還將groupby-field添加到select。

我希望能夠創建一個groupby而不必投影groupby字段本身。查詢應類似於此：

SELECT this_.Id      as Id8_0_ 
FROM CI.BM_RECONCILIATION_SIDE this_ 
WHERE this_.Id in (SELECT 
         min(this_0_.BM_RECONCILIATION_SIDE) as y1_ 
       FROM  CI.BM_RECON_ITEM_RECON_SIDE this_0_ 
       WHERE this_0_.BM_RECON_ITEM in (345061 /* :p0 */,345877 /* :p1 */) 
       GROUP BY this_0_.BM_RECON_ITEM)

不知道如何解決這個問題？

好吧，它似乎仍然是一個open issue與nHib。
像他們總是說 - 歡迎你自己實現它.. :)

謝謝 - 它並沒有讓我接近任何解決方案，但它確實表明，我不是唯一一個這個問題。 –
