How to convert SQLite values to custom Python types How to adapt custom Python types to SQLite values I'm guessing the latter because the current version of the application works for me and the feature not working for you is very fundamental and has probably worked from the application's inception.How to use placeholders to bind values in SQL queries ![]() Whether that is because your "DB Browser for SQLite" is failing or because you are misusing that application is impossible to see in that little video. In this case, it is not being properly instructed. To repeat and underscore Simon's observation: The SQLite library, as released, has never had such a fundamental failure as "Database does not update" when properly instructed. My initial reaction to invitations such as "Dig through this load of mostly extraneous information to see what I'm doing" is to decline under this hypothesis: If somebody cannot take the trouble to abstract and report what they see as the relevant aspects of their problem, then I see their problem as worth very little trouble on my part. I was very tempted, as usual under similar circumstances, to just ignore your post. This makes me think there is something going wrong for you which is not evident in your video. This was after creating the DB in a directory for which I had write permission. When I install the same application on my Xubuntu system, then modify some fields using the same sequence as shown in your video, I can close the DB, reopen it, and observe that the modified values are still there. I concur with Simon's comments on this, and have a few more.
