Split function equivalent in T-SQL?

Question

I’m looking to split \'1,2,3,4,5,6,7,8,9,10,11,12,13,14,15...\' (comma delimited) into a table or table variable.

Does anyone have a function that returns each one

Answer 1

CREATE Function [dbo].[CsvToInt] ( @Array varchar(4000)) 
returns @IntTable table 
(IntValue int)
AS
begin
declare @separator char(1)
set @separator = ','
declare @separator_position int 
declare @array_value varchar(4000) 

set @array = @array + ','

while patindex('%,%' , @array) <> 0 
begin

select @separator_position = patindex('%,%' , @array)
select @array_value = left(@array, @separator_position - 1)

Insert @IntTable
Values (Cast(@array_value as int))
select @array = stuff(@array, 1, @separator_position, '')
end
