Hi wheresjim,
Here's another way. Now that I wrote it, I think I like Steve's version
better - but since YMMV, I'll post it anyway.
DECLARE @a varchar(40)
SET @a = 'segment1-segment2-segment3'
SELECT REVERSE(SUBSTRING(REVERSE(SUBSTRING(@a,
CHARINDEX('-', @a) + 1,
LEN(@a))),
CHARINDEX('-', REVERSE(@a)) + 1,
LEN(@a)))
Best, Hugo
