抓取除最小值之外的所有ID

Question

我正在尝试从KeyLocationIDs获取其他NumberOfDuplicates。我想要排除Min(KeyLocationID)并想要其他人的列表。

select CompanyID, Location, EventCode, count(*) as NumberOfDuplicates, min(KeyLocationID) as KeepThisOne
from trip.KeyLocations
group by CompanyID, Location, EventCode
having count (*) > 1
order by location asc

Answer 1

你在这里缺少的是法令。 有几种方法可以做到这一点，这里有一些例子： 由@nobody吸食 或者你可以这样做：

select CompanyID, Location, EventCode, count(*) as NumberOfDuplicates, 
min(KeyLocationID) as KeepThisOne
from trip.KeyLocations
group by CompanyID, Location, EventCode
having KeyLocationID > min(KeyLocationID)
order by location asc

或者你可以这样做：

select CompanyID, Location, EventCode, count(*) as NumberOfDuplicates, 
min(KeyLocationID) as KeepThisOne
from trip.KeyLocations
group by CompanyID, Location, EventCode
having KeyLocationID != MIN(KeyLocationID)
order by location asc

Answer 2

选择CompanyID，Location，EventCode，count（）作为NumberOfDuplicates 来自trip.KeyLocations 哪里 KeyLocationID不在（通过CompanyID，Location，EventCode从trip.KeyLocations组中选择min（KeyLocationID）） 按CompanyID，Location，EventCode分组 有计数（）＆gt; 1 按地点排序asc
