Sql 获取SelectSum的别名

我试图在NHibernate中复制此SQL查询：

SELECT player.NAME, 
       Sum(achievement.value) AS 'Goals Scored' 
FROM   player 
       JOIN playerperformance 
         ON playerperformance.player_id = player.id 
       JOIN achievement 
         ON achievement.playerperformance_id = playerperformance.id 
WHERE  achievement.descriptor = 'Goals Scored' 
GROUP  BY player.NAME, 
          player.id 
ORDER  BY 'Goals Scored' DESC 

以下是我的NHibernate LINQ查询：

_dataAccessor.QueryOver<Player>()
    .Inner.JoinQueryOver<PlayerPerformance>(player => player.Performances)
    .Inner.JoinQueryOver<Achievement>(perf => perf.Achievements, () => achievementAlias)
    .Where(a => a.Descriptor == "Goals Scored")
    .SelectList(list => list.SelectGroup(player => player.Id).SelectSum(() => achievementAlias.Value))
    .OrderBy(a => a.Value).Desc
    .List()
    ;

因此，我所需要做的就是说服NHibernate按y1进行排序，而不是按成就进行排序。但我想不出如何得到总和的别名

---

有什么想法吗？

我想出来了

SelectSum（…）

有一个

WithAlias

方法，因此我可以指向表示总和的整数别名。然后我不得不使用

OrderByAlias（…）

而不是

OrderBy（…）

：

int-sumalas=0；
_dataAccessor.QueryOver（）
.Inner.JoinQueryOver（player=>player.performance）
.internal.JoinQueryOver（性能=>性能成就，（）=>achievementAlias）
.其中（a=>a.描述符==“得分”）
.SelectList（list=>list.SelectGroup（player=>player.Id）。SelectSum（（）=>achievementAlias.Value）。WithAlias（（）=>sumAlias）
.OrderByAlias（（）=>sumAlias）.Desc
.List（）
;

SELECT this_.id                AS y0_, 
       Sum(achievemen2_.value) AS y1_ 
FROM   [player] this_ 
       INNER JOIN [playerperformance] playerperf1_ 
               ON this_.id = playerperf1_.player_id 
       INNER JOIN [achievement] achievemen2_ 
               ON playerperf1_.id = achievemen2_.playerperformance_id 
WHERE  achievemen2_.descriptor = @p0 
GROUP  BY this_.id 
ORDER  BY achievemen2_.value DESC 

int sumAlias = 0;

_dataAccessor.QueryOver<Player>()
    .Inner.JoinQueryOver<PlayerPerformance>(player => player.Performances)
    .Inner.JoinQueryOver<Achievement>(perf => perf.Achievements, () => achievementAlias)
    .Where(a => a.Descriptor == "Goals Scored")
    .SelectList(list => list.SelectGroup(player => player.Id).SelectSum(() => achievementAlias.Value).WithAlias(() => sumAlias)
    .OrderByAlias(() => sumAlias).Desc
    .List<object[]>()
    ;
