Loop OR dataset in Store procedure

Hello ,
I want in a store procedure in SQL to have a loop.
I asctually want to SELECT something from a table and then
for each record of the results do something (another selection etc ) is
this posible in a store procedure ?
I know how to do this in vb.net but i want it to be really fast so i am
searching for a way to do this in a store procedure
example:
Select distinct(code) from Table1
for each code
select year from table2 where code=code (of the selection
for ...
for ...
next ...
next ...
The above is an example of what i want to do in the store procedure.
Are you sure you can't use a set statemet?
If not take a look at cursors in BOL

|||Perhaps. But there's nothing in the original post to indicate that that
would be necessary or desirable. The OP said "for each record ... do
something (another selection etc)". If "do something" means "select or
update some other data" then chances are the simplest and most
efficient solution is to do a join using set-based SQL code. CLR isn't
the natural place to do data retrieval and manipulation.

You can use a temp table and pull information from it one row at a time
in a loop.If you use a cursor, make sure it is read only, forward only,
and local.
