sql-server-2008 - 分组选择语句

Question

我有这个丑陋的SELECT声明：

        Select 'Urbain' as Véhicule, Count( DISTINCT Plaintes.IDEvenements) as Hebdomadaire
        FROM Plaintes join PVehicule on Plaintes.IDEvenements = PVehicule.IDEvenements 
        join EvVehicule on PVehicule.IDVehicule = EvVehicule.IDVehicule
        join Classe_Vh on EvVehicule.IDClasse = Classe_Vh.IDClasse
        join Type_Voy on Classe_Vh.IDTYPE_VOYAGE = Type_Voy.IDTYPE_VOYAGE
        Where Plaintes.Date >= @Sunday AND Plaintes.Date < DATEADD(Day, 7, @SUNDAY) AND Description = 'Urbain'

这给了我这个结果：

我需要复制这个查询几次并更改一个简单的关键字，比如NolisetoScholar等等。

我知道如果我只是复制它，我会收到不同的请求：

我想要的是一个包含所有内容的数组，就好像它是一个单独的SELECT而不改变我的整个请求一样。有没有简单的方法可以做到这一点？

编辑：

假设我想添加另一个必须检查另一个日期条件的列。

Hebdomadaire 这意味着每周一次的英语测试，看看它是否在本周：

         Where Plaintes.Date >= @Sunday AND Plaintes.Date < DATEADD(Day, 7, @SUNDAY)

我会添加一个年度专栏来对此进行测试：

         Where Plaintes.Date >= 2012/01/01

我怎样才能进行查询，以便只对第一个条件进行每周测试？

Answer 1

使用GROUP BY Description：

SELECT
    Description as Véhicule,
    Count(DISTINCT Plaintes.IDEvenements) as Hebdomadaire
FROM Plaintes
JOIN PVehicule ON Plaintes.IDEvenements = PVehicule.IDEvenements 
JOIN EvVehicule ON PVehicule.IDVehicule = EvVehicule.IDVehicule
JOIN Classe_Vh ON EvVehicule.IDClasse = Classe_Vh.IDClasse
JOIN Type_Voy ON Classe_Vh.IDTYPE_VOYAGE = Type_Voy.IDTYPE_VOYAGE
WHERE Plaintes.Date >= @Sunday AND Plaintes.Date < DATEADD(Day, 7, @SUNDAY)
GROUP BY Description

Answer 2

Select description as Véhicule
    , Count( DISTINCT Plaintes.IDEvenements) as Hebdomadaire
FROM Plaintes join PVehicule on Plaintes.IDEvenements = PVehicule.IDEvenements 
join EvVehicule on PVehicule.IDVehicule = EvVehicule.IDVehicule
join Classe_Vh on EvVehicule.IDClasse = Classe_Vh.IDClasse
join Type_Voy on Classe_Vh.IDTYPE_VOYAGE = Type_Voy.IDTYPE_VOYAGE
Where Plaintes.Date >= @Sunday 
AND Plaintes.Date < DATEADD(Day, 7, @SUNDAY) 
AND Description IN ('Urbain','Scholar','otherthing')
