Answer : Duplicate rows in Datatable

the SPROC would be like this...  (you'll need to add the CREATE PROCEDURE heading etc)

select * into #temp from yourtable
alter table yourtable add idx int
go
update yourtable set idx = 1
insert into yourtable select #temp.*,2 from #temp
insert into yourtable select #temp.*,3 from #temp
insert into yourtable select #temp.*,4 from #temp
insert into yourtable select #temp.*,5 from #temp
drop table #temp
