For the results you showed, you don’t need a new split function. Just a normal one that takes a list and a separator.

SELECT
  second_split.*
FROM
  dbo.fn_split(@myList, ' ')   AS first_split
CROSS APPLY
(
  SELECT first_split.item
  UNION
  SELECT item FROM dbo.fn_split(first_split.item, ',')
)
  AS second_split

The first_split will be Hyderabad and Hyd,Test.

The second split will be…
– Hyderabad UNION Hyderabad which is just Hyderabad
– Plus Hyd,Test UNION Hyd and Test

Giving…

• Hyderabad
• Hyd,Test
• Hyd
• Test
