No, you're never too old to Yak'n'Roll if you're too young to die.

Are the first 2 bytes alway Alpha?

We need more sample Data

But could be as simple as


SELECT CONVERT(int, SUBSTRING(Col1,3,LEN(COL1) -1))
  FROM (
			SELECT 'LB1'	AS Col1 UNION ALL
			SELECT 'LB500'	AS Col1
) AS XXX

Would you expect 0 for LB?
