Sql server 查找EVA设计中缺少的属性数量。。。。（从此sql联接中删除子查询）

如何从以下示例中删除[Count of Missing Attributes]中的子查询

    --Setup data
    Declare @Attributes table (AttributeID int)
    Declare @Objects table (ObjectID int)
    Declare @ObjectAttributes table (ObjectID int, AttributeID int, val int)

    Insert Into @Objects (ObjectID) values (1)
    Insert Into @Objects (ObjectID) values (2)

    Insert Into @Attributes (AttributeID) values (1)
    Insert Into @Attributes (AttributeID) values (2)

    Insert Into @ObjectAttributes (ObjectID,AttributeID) values (1,1)
    Insert Into @ObjectAttributes (ObjectID,AttributeID) values (2,1)
    Insert Into @ObjectAttributes (ObjectID,AttributeID) values (2,2)

    --Query
    Select 
        ObjectID, 
        (Select Count(Distinct a2.AttributeID) FROM @Attributes a2) As [Total Count Of Attributes],
        Count(Distinct a.AttributeID) as [Count of attributes for this object],
        (Select Count(Distinct a2.AttributeID) FROM @Attributes a2) - Count(Distinct a.AttributeID) as [Count of Missing Attributes]
    FROM @Attributes a
    INNER Join @ObjectAttributes oa
        On oa.AttributeID = a.AttributeID 
    Group By ObjectID
    Order By ObjectID

这假定不存在重复数据。删除HAVING子句以包含没有属性的对象（这些属性在原始查询中被忽略）

Arg-不要将“sqlserver”用作标记。在您提出此问题时，没有其他“sqlserver”问题和7000多个“sqlserver”问题。现在，由于您创建了“sqlserver”标记，我不得不在另外两个地方用抱歉的Joel清理它，我只是点击得太快了

SELECT
   ob.Objectid
  ,count(at.Attributeid) [Total Count Of Attributes]      
  ,count(oa.Attributeid) [Count of attributes for this object]
  ,sum(case when oa.AttributeId is null then 1 else 0 end) [Count of Missing Attributes]
 from @Attributes at
  cross join @Objects ob
  left outer join @ObjectAttributes oa
   on oa.ObjectId = ob.ObjectId
    and oa.AttributeId = at.AttributeId
 group by ob.Objectid
 having count(distinct oa.Attributeid) > 0
