Short answer: you can't. It would require rebuilding every single page of the database.
Exception 1: If the database is empty, the pragma will set the page size. Exception 2: If your database is not empty and you run VACUUM (which rebuilds every page of the database anyway) immediately after issuing the pragma. -----Urspr?ngliche Nachricht----- Von: sqlite-users-bounces at mailinglists.sqlite.org [mailto:sqlite-users-bounces at mailinglists.sqlite.org] Im Auftrag von Jim Wang Gesendet: Donnerstag, 25.
