Answer / tdguy
I hope substr function can be used but somewhat lengthy.
But UDF would make task easy.
SEL SIX
FROM
(
SEL
CASE
WHEN SUBSTR(COLUMN,1,1) IN
('1','2','3','4','5','6','7','8','9','0')
THEN '1' ELSE '' END AS ONE,
CASE
WHEN SUBSTR(COLUMN,2,1) IN
('1','2','3','4','5','6','7','8','9','0')
THEN '2' ELSE '' END AS TWO,
CASE
WHEN SUBSTR(COLUMN,3,1) IN
('1','2','3','4','5','6','7','8','9','0')
THEN '3' ELSE '' END AS THREE,
CASE
WHEN SUBSTR(COLUMN,4,1) IN
('1','2','3','4','5','6','7','8','9','0')
THEN '4' ELSE '' END AS FOUR,
SUBSTR(TRIM(ONE||TWO||THREE||FOUR),1,1) AS FIVE,
SUBSTR(COLUMN,FIVE,1) AS SIX
