NOTE::

The MAXRECURSION query hint specifies the maximum number of recursions allowed for a query. The number of recursions is a non-negative integer between 0 and 32,767. When 0 is specified, no limit is applied.

If the MAXRECURSION query hint is not specified, the default limit is 100. When the specified or default number for MAXRECURSION limit is reached during query execution, the query is ended and an error is returned.

CHEERS!!!
