Help in Select query please

Question

Hi, How I can split the column (Root_Desc) into five. Need to split column after the hyphen ('_').
Select * from travel
Root_Desc
1100_AUS_04_RTOT_GT
1102_USA_3_RTOT_TT
Desired Output
Rout_No Dest_Country Desc_Code Rout_Desc Rout_Line
1100     AUS   04    RTOT    GT
1102     USA    3     RTOT   TT
Thanks.

You can use split function, say,
declare @travel table (Root_Desc varchar(max));
insert into @travel (Root_Desc) values ('1100_AUS_04_RTOT_GT'),('1102_USA_3_RTOT_TT');
;with cte as (select t.Root_Desc, F.Value, F.Id from @travel t
CROSS APPLY dbo.fnSplit(t.Root_Desc, '_') F)
select Root_Desc, [1] as Rout_No, [2] as Dest_Country,
[3] as Desc_Code,
[4] as Rout_Desc,
[5] as Rout_Line
from cte PIVOT (min(value) for ID IN ([1],[2],[3],[4],[5])) pvt
where fnSplit is table-valued function:
USE [AllTests]
GO
/****** Object: UserDefinedFunction [dbo].[fnSplit] Script Date: 1/5/2015 11:47:32 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- Test query
CREATE FUNCTION [dbo].[fnSplit]
(@list VARCHAR(8000),
@delim CHAR(1) = ','
) RETURNS TABLE AS
RETURN
WITH csvtbl(START, stop) AS (
SELECT START = 1,
stop = CHARINDEX(@delim COLLATE Slovenian_BIN2, @list + @delim)
UNION ALL
SELECT START = stop + 1,
stop = CHARINDEX(@delim COLLATE Slovenian_BIN2,
@list + @delim, stop + 1)
FROM csvtbl
WHERE stop > 0
SELECT row_number() over (order by Start) as ID, LTRIM(RTRIM(SUBSTRING(@list, START,
CASE WHEN stop > 0 THEN stop - START ELSE 0 END)))
AS VALUE
FROM csvtbl
WHERE stop > 0
GO
