select P.[Port Name], CR.Name as country,CASE 
when SIH.[Ship-to Code] = '' then (select C.Name from [Customer] C where C.No_ = SIH.[Sell-to Customer No_]) 
end as name, 
case 
when SIH.[Ship-to Code] = '' then (select C.Address from [Customer] C where C.No_ = SIH.[Sell-to Customer No_]) 
end as addr, 
case 
when SIH.[Ship-to Code] = '' then (select C.[City] from [Customer] C where C.No_ = SIH.[Sell-to Customer No_]) 
end as city 
from [Sales Invoice Header] SIH, [Port] P, [Country_Region] CR where No_ = 'PEXP1213-523' and P.Code = SIH.Port 
and CR.Code = SIH.[Country of Final Destination] 
union all 
select P.[Port Name], CR.Name as country, 
case 
when SIH.[Ship-to Code] <> '' then (select C.Name from [Ship-to Address] C where C.Code = SIH.[Ship-to Code] and C.[Customer No_] = SIH.[Sell-to Customer No_]) 
end as name, 
case 
when SIH.[Ship-to Code] <> '' then (select C.[Address] from [Ship-to Address] C where C.Code = SIH.[Ship-to Code] and C.[Customer No_] = SIH.[Sell-to Customer No_]) 
end as addr, 
case 
when SIH.[Ship-to Code] <> '' then (select C.[City] from [Ship-to Address] C where C.Code = SIH.[Ship-to Code] and C.[Customer No_] = SIH.[Sell-to Customer No_]) 
end as city 
from [Sales Invoice Header] SIH, [Port] P, [Country_Region] CR where No_ = 'PEXP1213-524' and P.Code = SIH.Port 
and CR.Code = SIH.[Country of Final Destination] 

Answer 1

select P.[Port Name], CR.Name as country, c.Name, c.Address, c.City 
from [Sales Invoice Header] SIH 
inner join Port P On P.Code = SIH.Port 
inner join Country_Region CR On CR.Code = SIH.[Country of Final Destination] 
inner join Customer C.No_ = SIH.[Sell-to Customer No_]) 
where No_ = 'PEXP1213-523' and SIH.[Ship_to Code] = '' 
union all 
select P.[Port Name], CR.Name as country, SIH.Name, SIH.Address,SIH.City 
From [Sales Invoice Header] SIH 
inner join Port P On P.Code = SIH.Port 
inner join Country_Region CR On CR.Code = SIH.[Country of Final Destination] 
Where No_ = 'PEXP1213-524' and SIH.[Ship_to Code] <> '' 

是一個更容易閱讀，並可能幫助你找出什麼是錯的。 使用ANSI連接語法，而不是前92的東西 和邪神的緣故，至少選擇一個命名約定爲您列和表。

哦，你可能必須在它所在的表中加上前綴No_，因爲我沒有線索。
