SQL Server：语句完成之前最大递归100已用尽

Question

我有一个查询返回的错误超过了递归的最大级别。

我知道如何通过将OPTION (maxrecursion 0)添加到查询来解决此问题，但是，我试图在查询中的各个位置添加此项，并且无法找到将语法放在何处的位置。

任何人都可以给我任何指针，以我在哪里查看提示需要插入？

的建议我已经加入OPTION（MAXRECURSION 0）略高于最后GO语句，但是当创建视图语句内它是给一个语法错误。如果我自己运行查询，它在创建视图语句之外运行

通常，在使用recurcive cte的select语句的末尾。
但是，在一个视图内，将无法正常工作。 快速搜索让我到this post - 这解释了正确的做法。

原来你不能在视图中使用查询提示，但你可以也应该在调用视图的查询中使用它。

样品表：

CREATE TABLE T 
(
    id int, 
    parent int 
) 
INSERT INTO T VALUES (1, NULL), (2, 1), (3, 1), (4, 2), (5, 2), (6, 3), (7, 4), (8, 5); 
GO 

创建视图：

CREATE VIEW V 
AS 

WITH CTE AS 
(
    SELECT id, parent 
    FROM T 
    WHERE parent IS NULL 
    UNION ALL 

    SELECT t.id, t.parent 
    FROM T 
    INNER JOIN CTE ON t.parent = cte.id 
) 

SELECT * 
FROM CTE 

GO 

执行视图：

SELECT * 
FROM V 
OPTION (MAXRECURSION 2);
