Sorry, I did forget to include the splitstring function:

CREATE function [dbo].[SplitString]

(

@str nvarchar(4000),

@separator char(1)

)

returns table

AS

return (

with tokens(p, a, b) AS (

select

1,

1,

charindex(@separator, @str)

union all

select

p + 1,

b + 1,

charindex(@separator, @str, b + 1)

from tokens

where b > 0

)

select

p-1 zeroBasedOccurance,

substring(

@str,

a,

case when b > 0 then b-a ELSE 4000 end)

AS s

from tokens

)

GO

Edit BTW, this was probably not original, but if it isn't I'm not sure of the source.
