You can't get a callback when other processes change the database for many reasons. However it is possible to detect if the database has changed: https://www.sqlite.org/pragma.html#pragma_data_version https://www.sqlite.org/fileformat2.html#file_change_counter In theory some combination of file change notification from the OS (eg inotify) and inspecting the database should come close to meeting your needs.

[sqlite] Scope of sqlite3_update_hook?
Does a registered sqlite3_update_hook get called when _any_ SQLite connection modifies the database, or just the connection it's registered with? If so, then does that include connections in other OS processes? (I'm looking for a way to detect this.) --Jens [via iPhone] ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users

No, only the connection it's registered with. If so, then does that include connections in other OS processes? (I'm looking for a way to detect this.) There's nothing in SQLite that would help with that, to my knowledge. -- Igor Tandetnik ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
