我的查询返回错误,超出了最大递归级别。
我知道如何通过向查询添加OPTION (maxrecursion 0)
来解决这个问题,但是我尝试在查询中的各个位置添加它,我无法找到将其放在语法有效位置的位置。
任何人都可以给我任何关于我的视图中需要插入查询提示的指示吗?

如我所知,我已将 OPTION(maxrecursion 0)添加到最后一个GO语句的上方,但是当在create view语句中时,它会给出语法错误。如果我自己运行查询,那么在创建视图语句之外它可以运行

通常,在使用recurcive cte的select语句的末尾。
但是,在一个不起作用的视图中。
快速搜索让我this post - 这解释了正确的方法。
原来你不能在视图中使用查询提示,但你可以而且应该在调用视图的查询中使用它。
样本表:
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);

我使用了一个非常不错的脚本check foreign keys recursively by Ann Lewkowicz
但是,我曾经有一个数据库,该数据库有很多约束,包括某些表中的外键约束。
在运行上面的脚本时,出现以下错误:
该语句终止。最大递归32767已被 语句完成前筋疲力尽。
然后我使用top
限制了脚本的输出,一切都很好
select top 100 *
from recurseWithFields
--OPTION (MAXRECURSION 32767);
