Sql 服务器中的联盟递归查询
原标题:Union recursive queries in sql server

我需要合并两个不同的递归查询。

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

union all

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

How can I do it? I received error: Incorrect syntax near the keyword WITH .

我试图通过互联网搜索,但找不到。

问题回答

顺序应为:

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

您的所有 CTE 都需要在一系列语句的开头 。
