<p class="contentpasted0"><span style="font-family:"Calibri",sans-serif;color:black">first I would like to thank Bernhard Ströbl, Richard McDonnell, Andrea Giudiceandrea and Bernd Vogelgesang for suggestions related to some of my previous posts.<o:p></o:p></span></p>

<p class="contentpasted0"><span style="font-family:"Calibri",sans-serif;color:black">I have some tables already created that have a column with autogeneration id codes.<o:p></o:p></span></p>
<p class="contentpasted0"><span style="font-family:"Calibri",sans-serif;color:black"><o:p> </o:p></span></p>
<p class="contentpasted0"><span style="font-family:"Calibri",sans-serif;color:black">From self-generation I often don’t get codes that start from 1 onwards but start with other numbers.<o:p></o:p></span></p>
<p class="contentpasted0"><span style="font-family:"Calibri",sans-serif;color:black"><o:p> </o:p></span></p>
<p class="contentpasted0"><span style="font-family:"Calibri",sans-serif;color:black">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.<o:p></o:p></span></p>
