aktualny kod roboczy z mysqli jest jak poniżej. Chciałbym przekonwertować go na przygotowane oświadczenia. istnieje zasadniczo trzy kwerendy sql, które należy przekonwertować do przygotowanej instrukcji. pierwsza część jest dla mnie najtrudniejszą częścią, aby wymyślić przygotowany sposób na uzyskanie wartości zliczania, którą w końcu udało mi się rozgryźć.
