SQL Server : the maximum recursion 100 has been exhausted before statement completion

Question

我有一个查询返回错误，并且超出了最大递归级别。

我知道如何通过添加 OPTION (maxrecursion 0) 来解决此问题但是，对于查询，我尝试将其添加到查询中的各个位置，但找不到将其放置在语法有效的位置的位置。

任何人都可以给我任何关于在我看来需要插入查询提示的位置的指示吗？

按照建议，我已将 OPTION (maxrecursion 0) 添加到最后一个 GO 语句的上方，但是在创建 View 语句中时，它会出现语法错误。如果我在创建 View 语句之外单独运行查询，它就可以工作

通常，在使用递归 cte 的 select 语句的末尾。
然而，在一个 View 里面是行不通的。 快速搜索让我找到了this post - 这解释了正确的方法。

事实证明，您不能在 View 内使用查询提示，但您可以而且应该在调用 View 的查询中使用它。

示例表:

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 View :

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 View :

SELECT *
FROM V
OPTION (MAXRECURSION 2);
