如何色谱柱结合两个表

Question

的我有三个临时列，

1. @Pid (PartyId bigint)它包含了所有Partyid

2. @t PartyID bigint,PartyName varchar(50)SaleQty decimal(18,2))它包含财政年度15-16各方的 销售历史。

3. @ty PartyID bigint,PartyName varchar(50)SaleQty decimal(18,2))它包含 财政年度16-17各方的销售历史。

我想两个临时表@t和@ty这样的方式的 记录两融创的任何一方ID应该是在一排相结合。并且如果任何partyid没有进入表@t和@ty中的任何一个，那么在该财政年度销售额Q应该为零。

我已经做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 

，但我无法得到期望的结果。请在这里帮助我一些。

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

您需要@Pid是“基地”表中，左连接两个表吧。 你还需要使用COALESCE（或ISNULL）从它存在任何临时表中获取的党名。

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
