Question

I want to reference the nth row of the #temptable (at the second SQL comment is below). What expression will allow me to do so?

DECLARE @counter INT
SET @counter = 0
WHILE (@counter<count(#temptable))
--#temptable has one column and 0 or more rows
BEGIN
DECLARE @variab INT
EXEC @variab = get_next_ticket 3906, 'n', 1

INSERT INTO Student_Course_List
                SELECT  @student_id,
                -- nth result set row in #temptable, where n is @count+1
                @variab

SET @counter = @counter +1
END

Cursor (will this work?):

for record in (select id from #temptable) loop 
--For statements, use record.id 
end loop;

Answer 1

Instead of using a while loop (with a counter like you are doing) to iterate the table you should use a cursor

Syntax would be:

DECLARE @id int
DECLARE c cursor for select id from #temptable
begin
  open c
    fetch next from c into @id
    WHILE (@@FETCH_STATUS = 0)
    BEGIN
      --Do stuff here
      fetch next from c into @id
    END
  close c
  deallocate c
end
