I'd read the given documentation http://getbootstrap.com/javascript/#affix

I try with .affix but the result is zero.

Update: @Skelly,

Bootstrap 3

Here is a working left sidebar example:

http://bootply.com/90936 (similar to the Bootstrap docs)

The trick is using the affix component along with some CSS to position it:

  #sidebar.affix-top {
    position: static;
    margin-top:30px;
    width:228px;
  }

  #sidebar.affix {
    position: fixed;
    top:70px;
    width:228px;
  }

EDIT- Another example with footer and affix-bottom

Bootstrap 4

The Affix component has been removed in Bootstrap 4, so to create a sticky sidebar, you can use a 3rd party Affix plugin like this Bootstrap 4 sticky sidebar example, or use the sticky-top class is explained in this answer.
