What is the maximum recursion level in msdn?


Asked by Katelyn Guerrero on Dec 10, 2021 FAQ



But you can change the level by using the MAXRECURSION option/hint. The recursion level ranges from 0 and 32,767. The statement terminated. The maximum recursion 100 has been exhausted before statement completion. Let’s check this with an example discussed in MSDN TSQL forum, link:
Furthermore,
But you can change the level by using the MAXRECURSION option/hint. The recursion level ranges from 0 and 32,767. If your CTEs recursion level crosses the limit then following error is thrown by SQL Server engine: The statement terminated. The maximum recursion 100 has been exhausted before statement completion.
In fact, To prevent an infinite loop, you can limit the number of recursion levels allowed for a particular statement by using the MAXRECURSION hint and a value between 0 and 32,767 in the OPTION clause of the INSERT, UPDATE, DELETE, or SELECT statement.
Accordingly,
When 0 is specified, no limit is applied. If this option isn't specified, the default limit for the server is 100. When the specified or default number for MAXRECURSION limit is reached during query execution, the query ends and an error returns. Because of this error, all effects of the statement are rolled back.
Additionally,
The sys module in Python have a function getrecursionlimit () can show the recursion limit in your Python version. You can change this limitation but it’s very important to know if you increase it very much you will have memory overflow error. So be careful before increase it.
