Hi.I'd like to delete everything after the last "-" found in the string.
I mean if I have these fields:

L-Arginine 500 mg - 100 Capsules
L-Carnitine 250 mg - 30 Caps
SAMe 400 mg Vegetarian - 30 Tablets
Pro-GH#8482; - 600 g (21.2 oz.)
L-Arginine Powder - 1 lb.
.
.
.

I need to get these results:

L-Arginine 500 mg
L-Carnitine 250 mg
SAMe 400 mg Vegetarian
Pro-GH#8482;
L-Arginine Powder
.
.
.

please help.
Thanks in advanced

DECLARE @string varchar(100)
set @string = 'L-Arginine 500 mg - 100 Capsules'

select reverse(right(reverse(@string),len(@string) - charindex( '-', reverse(@string))) )

Well that seems to work nicely


DECLARE @string varchar(100)

set @string = 'L-Arginine 500 mg - 100 Capsules'
select reverse(right(reverse(@string),len(@string) - charindex( '-', reverse(@string))) )

set @string = 'L-Arginine 500 mg - 100 Capsules - Bretts Tequila'
select reverse(right(reverse(@string),len(@string) - charindex( '-', reverse(@string))) )
