[Qgis-user] Autogeneration id codes

[Riccardo]

Good morning to all,


first I would like to thank Bernhard Ströbl, Richard McDonnell, Andrea Giudiceandrea and Bernd Vogelgesang for suggestions related to some of my previous posts.


Now I have another problem.....


I have some tables already created that have a column with autogeneration id codes.


>From self-generation I often don’t get codes that start from 1 onwards but start with other numbers.


I made some tests and I noticed that if I create a table and add 10 lines the autogeneration creates id codes from 1 to 10. If I delete these lines to empty the table when I create a new line Qgis autogenerates that with the code 11, it seems that Qgis keeps in memory the number/id code of the created elements, and keep the numbering as a fixed counter.


How can I impose a autogeneration of id codes starting from 1?


Many many thanks!


Best Regards.


Riccardo.
