The table-valued function [dbo].[TableFormDelimetedStringWithoutNumberList] will choke on lists longer than 100 elements. Here's the error:

Msg 530, Level 16, State 1, Line 1

The statement terminated. The maximum recursion 100 has been exhausted before statement completion.

Using OPTION(MAXRECURSION xxx) is not allowed within a UDF, so the numbered list seems to be the only alternative for large lists. Am I missing something?
