使用完全外部联接加入两个临时 Table

Question

我想用完全外连接连接两个临时表，但不能正常工作总是只显示#RMS 值而不显示#RMB !!

这段代码哪里出了问题？

(#RMS 没有空值)

create table #RMS 
(
    [Year] int,
    [Month] int,
    sTAccount bigint,
    sRemaining bigint
)
insert into #RMS(Year,Month,sTAccount,sRemaining)
select
    YEAR(Date) [Year],
    DATEPART(MONTH,Date) [Month],
    sum(TAccount) sTAccount,
    sum(Remaining) sRemaining
from
    SaleInvoices
group by YEAR(Date),DATEPART(MONTH,Date)
order by YEAR(Date),DATEPART(MONTH,Date)

( #RMB without null but sometimes #RMB Month Column Value and #RMS Month Column value is Different )

create table #RMB 
(
    [Year] int,
    [Month] int,
    bTAccount bigint,
    bRemaining bigint
)
insert into #RMB(Year,Month,bTAccount,bRemaining)
select
    YEAR(Date) [Year],
    DATEPART(MONTH,Date) [Month],
    sum(TAccount) bTAccount,
    sum(Remaining) bRemaining
from
    BuyInvoices
group by YEAR(Date),DATEPART(MONTH,Date)
order by YEAR(Date),DATEPART(MONTH,Date)

select * from #RMS
Full Outer Join #RMB
on #RMS.Year=#RMB.Year and #RMS.Month=#RMB.Month
group by #RMS.Year, #RMS.Month
order by #RMS.Year, #RMS.Month

感谢您的回答

Answer 1

您的 SELECT 列表有误。将 * 替换为 #RMS.*, #RMB.* 或（更好）您想要的字段的明确列表，在它们的名称前加上它们来自的 table 的名称。这也允许不重复您加入的字段。
