How to perform recursion more than 32767 in cte?


Asked by Jayce Kent on Dec 10, 2021 FAQ



How to perform recursion more than 32767. There is no way to perform a recursion more than 32767, if you increase the value of MAXRECURSION more than 32767, as you will get an error. You can define the maximum number of recursions for CTE, using the MAXRECURSION option.
Also,
There is no way to perform a recursion more than 32767, if you increase the value of MAXRECURSION more than 32767, as you will get an error. You can define the maximum number of recursions for CTE, using the MAXRECURSION option. Set the value of MAXRECURSION to 0, if you don’t know the exact numbers of recursions.
Indeed, 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.
Furthermore,
Lets Look at an example of Using Recursive CTE in SQL Server. Following statement uses recursive CTE and returns numbers from 1 to 100 . WITH cte AS ( SELECT 1 AS n UNION ALL SELECT n + 1 FROM cte WHERE n < 100\u2029
Additionally,
The execution order of a recursive CTE is as follows: First, execute the anchor member to form the base result set (R0), use this result for the next iteration. Second, execute the recursive member with the input result set from the previous iteration (Ri-1) and return a sub-result set (Ri) until the termination condition is met.
