sql - sql server中的联合递归查询

Question

我需要联合两个不同的递归查询。有人认为：

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

union all

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

我该怎么做？我收到错误：关键字“WITH”附近的语法不正确。

你知道有什么解决方法吗？我试图通过互联网搜索，但我找不到它..

Answer 1

顺序应该是：

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

你所有的CTEs 都需要在一系列语句的开头。
