如何連接使用SQL Server

Question

我在那裏的數據是一樣

Data 

a 
b 
c 

表我需要寫一個SQL查詢，使下面的輸出

Data 

abc 

如何做同樣的通過在SQL Server 2000中使用 謝謝

Answer 1

我不知道如何使用XML RAW來完成。儘管這種方法在SQL2000中有效。

DECLARE @Data varchar(8000) 
set @Data ='' 
select @Data = @Data + Data 
FROM @t 
ORDER BY Data 

SELECT @Data 

編輯哦，我剛纔看到這裏凱德給你一個鏈接您的其他問題。該鏈接上的KM's answer是否適合您？
