I need actually to duplicate 5 times. I need also to create a new column so that each duplicate has its own number in that column, ranging from 1 to 5.
Originally I planned to do this in code, but maybe it is better to do this in SPROC. What do you think?
 Can you help me with that or should I post the question again for the sql group in this forum?

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
