Answer / tdguy
Assuming the column to be char(2), we can use the following
sql to retrieve the numeric values.
SEL C1 FROM
(SEL C1,
CASE
WHEN SUBSTR(C1,1,1) IN
('1','2','3','4','5','6','7','8','9','0')
THEN 'N'
WHEN SUBSTR(C1,1,1) IN (' ')
THEN 'S'
END AS ONE,
CASE
WHEN SUBSTR(C1,2,1) IN
('1','2','3','4','5','6','7','8','9','0')
THEN 'N'
WHEN SUBSTR(C1,2,1) IN (' ')
THEN 'S'
END AS TWO FROM STUD2
) A
WHERE ((A.ONE='N' AND A.TWO='N')
OR
(A.ONE='N' AND A.TWO='S')
OR
(A.ONE='S' AND A.TWO='N'))
