Question

我有三个临时列，

@Pid (PartyId bigint)包含所有Partyid
@t PartyID bigint,PartyName varchar(50)SaleQty decimal(18,2)) 财政年度15-16各方的销售历史。
@ty PartyID bigint,PartyName varchar(50)SaleQty decimal(18,2)) 16-17财政年度各方的销售历史。

我想结合两个临时表@t和@ty这样的记录方式两个财务记录的任何一方都应该在一行中。如果有的话 partyid没有表@t和@ty中任何一个的条目 saleQty应该是该财政年度的零。

我已经完成了以下查询来解决这个问题。

select  A.PartyName,isnull(SUM(A.SaleQty),0) as TotalSale,isnull(SUM(B.SaleQty),0) as TotalSaleB  
from @t  A 
left join @ty B ON B.PartyId=A.PartyID
inner join @Pid P on P.PartyID=A.PartyID and B.PartyID=P.PartyID 
where PartyName like'%Jain'
group by A.PartyID,A.PartyName

我的输出是

 PartyName               TotalSale(15-16)      TotalSale(16-17)   
 JAIN TRADERS (DHAMPUR) 16682.00                 9699.00

我想要的结果应该是

 PartyName               TotalSale(15-16)      TotalSale(16-17)   
 JAIN TRADERS (DHAMPUR)   389.00                    139.00
 Sourav Traders           3899.00                   0.00
 Tickrej Traders         0.00                      0.00

但我无法得到理想的结果。请帮帮我一个。

试试这个：

declare  @Pid table (PartyId bigint)
insert into @Pid values (1)
insert into @Pid values (2)
insert into @Pid values (3)
insert into @Pid values (4)


declare @t table (PartyID bigint, PartyName varchar(50), SaleQty decimal(18,2))
insert into @t values(1, 'a', 10)
insert into @t values(1, 'c', 5)
insert into @t values(2, 'b', 10)
insert into @t values(4, 'b', 20)

declare @ty table(PartyID bigint,PartyName varchar(50), SaleQty decimal(18,2))
insert into @ty values(1, 'a', 10)
insert into @ty values(2, 'c', 15)
insert into @ty values(2, 'b', 10)


select c.PartyID as PartyID, ISNULL(sum(A.SaleQty), 0) as TotalSale15_16 into #A
from @t  A right join @Pid c on A.PartyID = c.PartyId
group by C.PartyID

select c.PartyID as PartyID,ISNULL(sum(B.SaleQty), 0) as TotalSale16_17 into #B
from @ty  B right join @Pid c on  B.PartyID = c.PartyId
group by C.PartyID

select A.PartyID, ISNULL(a.TotalSale15_16, 0) as TotalSale16_17, ISNULL(b.TotalSale16_17, 0) as TotalSale16_17 
from #A a join #B b on a.PartyID = b.PartyID

drop table #A
drop table #B


result:

PartyID TotalSale16_17  TotalSale16_17
1   15.00   10.00
2   10.00   25.00
3   0.00    0.00
4   20.00   0.00

Answer 2

您需要@Pid作为“基础”表，并将两个表连接到它。您还需要使用COALESCE（或ISNULL）从其所在的临时表中获取聚会名称。

SELECT COALESCE(A.PartyName, B.PartyName), 
       COALESCE(SUM(A.SaleQty, 0)) TotalSale_t,
       COALESCE(SUM(B.SaleQty, 0)) as TotalSale_ty
FROM @Pid C
LEFT JOIN @t A ON C.PartyId = A.PartyId
LEFT JOIN @ty B ON C.PartyId = B.PartyId
GROUP BY A.PartyName, B.PartyName
