Saya menggunakan akun root membuat akun 'a'@'%'. Tapi saya tidak bisa menggunakan akun untuk terhubung ke server MySQL ketika saya menentukan parameter host. Saya dapat berhasil terhubung tanpa -hparameter. Silakan lihat transkrip di bawah ini. Saya harap seseorang dapat membantu saya menjelaskannya. Terima kasih.
