I got the code below off the internet but the syntax is off.. What is the best way to create a UDF that pulls the last word out of a string?
CREATE FUNCTION dbo.ufn.Utility_Last_Word(@myString VARCHAR(4000) )
 RETURNS VARCHAR(4000)
 
RETURN
WITH find_last_blank(pos) AS (
VALUES LENGTH(@myString)
UNION ALL
SELECT pos - 1
  FROM find_last_blank
 WHERE pos > 0
   AND SUBSTR(in_string, pos, 1) <> ' '
)
SELECT SUBSTR(in_string, MIN(pos) + 1)
  FROM find_last_blank
;
