在sql server中聯合遞歸查詢

Question

我需要聯合兩個不同的遞歸查詢。 Somethink like：

with cte1 as 
(select.... 
.... 
.... 
) 
select * from cte1 

union all 

with cte2 as 
(select.... 
.... 
.... 
) 
select * from cte2 

我該怎麼辦？我收到錯誤： 關鍵字'WITH'附近的語法錯誤。

你知道任何workaroud嗎？我試圖尋找過互聯網，但我不能找到它..

Answer 1

的順序應該是：

;WITH Cte1 AS 
(
.... 
), 
Cte2 AS 
(
.... 
) 
SELECT * FROM Cte1 
UNION ALL 
SELECT * FROM Cte2 

你的所有CTE的需要是在一系列的語句開頭。
