Hi Francisco, In fact, the first of the two solutions I gave in that link is supposed to work on a general database file. I don't have time to look deeper right now, but why don't you give more details, such as a link to some sample file you're using (it better be large), and some code you tried (you can also post on StackOverflow). In this way, it will be easier to identify the problem / bottleneck. Hope you get well!
