I should probably know this but I don't.

I have a records set, let's keep it simple

Select email_address from contacts where email_address is not null

It returns a list of rows. duh.

Now, I want to iterate through the records set and do some for each.  

--Start loop

Exec sp_do_something 'email_address"

--end loop

What is the proper syntax to do this in MSSQL (replace the start loop and end loop.

declare @emails table (i int identity, EmailAddress varchar(100) )
declare @I int, @EmailAddress varchar(100)

insert into @emails
Select email_address from contacts where email_address is not null
select @I = @@rowcount

While @I >  0
BEGIN
   SELECT @EmailAddress = EmailAddress, @I = @I -1 from @Emails
   EXEC ProcDoSomething @EmailAddress
END

the logic stays as aneesh said above, but it is better to use curosors or just a where clause to what aneesh did above

declare @t Cursor 
for
select email_address from <your table>
open @t
FETCH @t into @email
while @@FETCH_STATUS = 0
BEGIN
  EXEC <your Proc> @email
  FETCH @t into @email
END
