SQL Server 2014如何从2个表制作单行结果

Question

Can anyone please help me with making a query? I have 2 tables, Articles and WareHouse:

The Article table have this record:

ArticleCode   ArticleName
  A120022      Article1

The Second Table have this Records:

WArticleCode    WareHouseNo    Quantity
  A120022            1            18
  A120022            2             7
  A120022            2             3
  A120022            2             3
  A120022            1            11
  A120022            1            22
  A120022            3             1
  A120022            2             8
  A120022            3             9
  A120022            3             3
  A120022            1             9

What I'm trying to accomplish is to Have this result:

ArticleCode   ArticleName   ArtInDISTWareh   TotalQua  WareHouses
  A120022       Article1          3            94      W1-60 ; W2-21 ; W3-13

I made this Query:

SELECT a.ArticleCode
      ,a.ArticleName
      ,ISNULL(b.WareHouseNo, 1) AS WareHouse
      ,ISNULL(SUM(b.Quantity),0) AS Quantity
  FROM [BazaZaWeb].[dbo].[Articles] a
  LEFT OUTER JOIN   WareHouse b ON b.WArticleCode = a.ArticleCode COLLATE DATABASE_DEFAULT
  GROUP BY a.ArticleCode,a.ArticleName,b.WareHouseNo

And this is the result:

ArticleCode ArticleName WareHouse   Quantity
  A120022    Article1      1           60
  A120022    Article1      2           21
  A120022    Article1      3           13

I can get almost what I want but not Grouping By b.WareHouseNo and using Distinct, but I cant figure out how to count the Warehouses in which the article exists (ArtInDISTWareh)

Thank You in advance for Your help

Answer 1

try following:

    declare @Article table (ArticleCode varchar(10), ArticleName varchar(100))
    declare @WareHouse table (WArticleCode varchar(10), WareHouseNo int, Quantity int)

    insert into @Article 
    select 'A120022','Article1'

    insert into @WareHouse
    select 'A120022',1,18 union all
    select 'A120022',2, 7 union all
    select 'A120022',2, 3 union all
    select 'A120022',2, 3 union all
    select 'A120022',1,11 union all
    select 'A120022',1,22 union all
    select 'A120022',3, 1 union all
    select 'A120022',2, 8 union all
    select 'A120022',3, 9 union all
    select 'A120022',3, 3 union all
    select 'A120022',1, 9

    select WArticleCode, WareHouseNo, (select sum(Quantity) from @WareHouse where WArticleCode = w.WArticleCode) TotalQuantity, 
'W' + convert(varchar(10), WareHouseNo) + '-' + convert(varchar(10), sum(Quantity)) Warehouses 
into #temp
from @WareHouse w
group by WArticleCode, WareHouseNo

select distinct WArticleCode, TotalQuantity, Stuff(
  (SELECT N'; ' + Warehouses FROM #temp where WArticleCode = t.WArticleCode FOR XML PATH(''),TYPE)
  .value('text()[1]','nvarchar(max)'),1,2,N'') Warehouses
into #ftemp
from #temp t

select a.ArticleCode, a.ArticleName, isnull(nullif(len(Warehouses) - len(replace(Warehouses, ';', ''))+1, 1),1) ArtInDISTWareh, TotalQuantity, Warehouses
from @Article a
join #ftemp t on WArticleCode = a.ArticleCode

    drop table #temp
    drop table #ftemp

Thanks.

To get ArtInDISTWareh , all you need to do is add this to your select clause:

, count(distinct WarehouseNo) ArtInDISTWareh

To get information about more than one warehouse in a single record, do a google search on sql server stuff for xml path . As far as the values you are looking for specifically, there is not enough information in your question for anyone to provide assistance.
