Spilting Values In Rows.

Hi guys,
I have a table like this.

Declare @tbl as table(Invoiceid int,Dc varchar(100))

Insert into @tbl
Select 1,'101,102,104'union all
Select 2,'105,106,107' union all
Select 3,'110,111,112,113,114' union all
Select 4 ,'115'

I want to split the values in the column Dc.The output should be

Invoiceid Dc
1--------- 101
1--------- 102
1--------- 104
2--------- 105
2--------- 106
2--------- 107
... and so on.
Thanks for any help.
