字母序列生成的SQL Server

Question

我試圖生成一系列字母的，使用SQL Server。

假設我有一個表如下

DECLARE @Funding TABLE (FundingDetailID INT,FundingID INT, DetailDescription VARCHAR(50)) 
INSERT INTO @Funding (FundingDetailID ,FundingID , DetailDescription) VALUES (1,107,'Desc 1') 
INSERT INTO @Funding (FundingDetailID ,FundingID , DetailDescription) VALUES (1,107,'Desc 2') 
INSERT INTO @Funding (FundingDetailID ,FundingID , DetailDescription) VALUES (1,107,'Desc 3') 

我試圖得到下面的結果。

a) Desc 1 
b) Desc 2 
c) Desc 3 

如何生成「a)」, 「b)」, ...？我不允許添加任何額外的臨時表或表變量來存儲最初的字母。它們應該被生成。

這是要在SQL Server 2005中完成的。

有什麼想法？

感謝

Answer 1

使用ROW_NUMBER（）如下

DECLARE @Funding TABLE (FundingDetailID INT,FundingID INT, DetailDescription VARCHAR(50)) 
INSERT INTO @Funding VALUES (1,107,'Desc 1') 
INSERT INTO @Funding VALUES (1,107,'Desc 2') 
INSERT INTO @Funding VALUES (1,107,'Desc 3') 

SELECT CHAR (CAST (96+ROW_NUMBER() OVER (Order BY FundingDetailID) AS VARCHAR)) + ') ' + DetailDescription 
FROM @Funding 



----------------------------------------------------- 
a) Desc 1 
b) Desc 2 
c) Desc 3

拉吉更已經發布的row_number()，而我寫它。我投了他的答案，但這是我的變種，在桌子上做了更新，以防萬一你對此感興趣。

update f1 
set  f1.DetailDescription = char(96 + f2.rn) + ') ' + f2.DetailDescription 
from @Funding f1 
join (
     select row_number() over (order by FundingDetailId, 
             FundingId, DetailDescription) as rn 
     ,  * 
     from @Funding f 
     ) f2 
on  f1.FundingDetailID = f2.FundingDetailID 
     and f1.FundingID = f2.FundingID 
     and f1.DetailDescription = f2.DetailDescription 

select * 
from @Funding
