语句被终止。完成执行语句前已用完最大递归 100

sql语句递归查询会员的推荐或安置关系时报错：语句被终止。完成执行语句前已用完最大递归……

服务器范围的默认值为 100。如果指定 0，则没有限制。每一个语句只能指定一个 MAXRECURSION 值使用类似的语句：

例如：

 1 USE AdventureWorks2008R2;
 2 GO
 3 --Creates an infinite loop
 4 WITH cte (EmployeeID, ManagerID, Title) as
 5 (
 6     SELECT EmployeeID, ManagerID, Title
 7     FROM dbo.MyEmployees
 8     WHERE ManagerID IS NOT NULL
 9   UNION ALL
10     SELECT cte.EmployeeID, cte.ManagerID, cte.Title
11     FROM cte 
12     JOIN  dbo.MyEmployees AS e 
13         ON cte.ManagerID = e.EmployeeID
14 )
15 --Uses MAXRECURSION to limit the recursive levels to 2
16 SELECT EmployeeID, ManagerID, Title
17 FROM cte
18 OPTION (MAXRECURSION 2);
19 GO
