What’s the easiest way to backup/restore sqlite memory database to file database in Qt.
I think you will need to work with SQLite directly to do this. SQLite has an Online Backup API, the first example is backing up an in-memory database to a file database, so it should be possible to do what you need to do.
To get a
sqlite3*database handle, get the driver (QSqlDatabase::driver) from the database then get the handle (QSqlDriver::handle). The example code in the Qt docs shows how to cast theQVariantinto asqlite3*handle.
