Hi All,
 
I have a column in a table which has the values in three combinations
 
i)Integer values(e.g 6361)
2)Integer values followed by two alphabets (e.g AA6063)
3)Integer values followed by three alphabets (e.g RDE40)
 
Now i need to get only the integer values in sql query.
 
I want the results for the above mentioned examples as
i) 6361
ii) 6063
iii) 40
 

How to get it in Sql Server 2008
 
Thanks...

Solution1 is very good, but uses loops. Alternatively, you can try something like this:
 
DECLARE @tmp TABLE (someText VARCHAR(30))
 
INSERT INTO @tmp (someText)
VALUES('6361')
INSERT INTO @tmp (someText)
VALUES('AA6063')
INSERT INTO @tmp (someText)
VALUES('RDE40')
 
SELECT someText, CONVERT(INT, SUBSTRING(someText, StartPos, EndPos)) AS MyNumeric
FROM(
	SELECT someText, PATINDEX('%[0-9]%',someText) AS StartPos, CASE
			WHEN PATINDEX('%[A-Za-z]%',SUBSTRING(someText, PATINDEX('%[0-9]%',someText) +1, LEN(someText)-PATINDEX('%[0-9]%',someText)))=0 THEN LEN(someText) 
			ELSE PATINDEX('%[A-Za-z]%',SUBSTRING(someText, PATINDEX('%[0-9]%',someText) +1, LEN(someText)-PATINDEX('%[0-9]%',someText)))
			END AS EndPos
FROM @tmp) AS T
 
Result:
someT.. MyNumeric
6361	6361
AA6063	6063
RDE40	40
