Split function for SQL Server

Function:

CREATE FUNCTION [dbo].[Split](@String varchar(8000), @Delimiter char(1))
returns @temptable TABLE (items varchar(8000))
as
begin
declare @idx int
declare @slice varchar(8000)

select @idx = 1
if len(@String)<1 or @String is null return

while @idx!= 0
begin
set @idx = charindex(@Delimiter,@String)
if @idx!=0
set @slice = left(@String,@idx – 1)
else
set @slice = @String

if(len(@slice)>0)
insert into @temptable(Items) values(@slice)

set @String = right(@String,len(@String) – @idx)
if len(@String) = 0 break
end
return
end

Usage:

DECLARE @NUMS VARCHAR(200)
SET @NUMS = ‘1,2,3,4, 5′
select LTRIM(RTRIM(items)) from Split(@NUMS,’,’)
