返回計數分組按類別隨着項目包含種類

Question

我有一個包含類似條目表變量：

locationID locationIDsub codetype code  codeTitle 
---------- ------------- -------- ---------- --------------- 
24   15   08  000000  Scooters 
51   15   08  000000  Scooters 
51   15   08  110000  Trucks 
24   15   08  110000  Trucks 
51   15   08  111011  Semis 
24   15   08  111011  Semis 
24   15   08  119061  Dump Trucks 
24   15   08  119071  Garbage Trucks 
51   15   08  254011  Cars 

我想是這樣的：

occcode occtitle    count locationID 
---------- ---------------------- ----- --------- 
000000  Scooters    2  24,51 
110000  Trucks     2  24,51 
111011  Semis     2  24,51 
119061  Dump Trucks   1  24 
119071  Garbage Trucks   1  24 
254011  Cars     1  51 

我能夠得到計數很好，只是無法使用以下方法獲得位置ID的計數+列表：

SELECT Res.code,Res.codetitle,count(Res.codetitle) 
FROM @resultsTable As Res 
JOIN [dbo].[mv_VEHCODE_Union] As Veh 
    ON Res.code= Veh.code AND Res.codetype = Veh.vehcodetype 
GROUP BY Res.code,Res.codetitle 
ORDER BY code 

下面是最終版本（仍在調整）我與基於丹尼斯的回答會（我放棄了數列，因爲僅用於調試）：

select distinct 
    v.code, 
    v.codetype, 
    locations = stuff((
     select distinct ',' + cast(locationid as varchar) 
     from @resultsTable v2 
     where v2.code=v.code and v2.codetype = v.codetype 
     for xml path('') 
    ),1,1,'') 
    from @resultsTable v 
    order by v.code 

Answer 1

你去那裏

select distinct 
v.code, 
v.codetype, 
cnt = (
    select count(*) 
    from mv_VEHCODE_Union v2 
    where v2.code=v.code and v2.codetype = v.codetype 
), 
locations = stuff((
    select distinct ',' + cast(locationid as varchar) 
    from mv_VEHCODE_Union v2 
    where v2.code=v.code and v2.codetype = v.codetype 
    for xml path('') 
),1,1,'') 
from mv_VEHCODE_Union v 
order by v.code
