-- For each position, you assign a string

Jika mendapatkan kesalahan berikut..
#1418 - This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you might want to use the less safe log_bin_trust_function_creators variable)
Jalankan kueri ini:
SET GLOBAL log_bin_trust_function_creators = 1;
Setelah itu Buat fungsi di Mysql:
Panggil fungsi Seperti perintah di bawah ini:
SELECT number_to_string( 666 );
Anda akan mendapatkan output sebagai:
number_to_string( 666 )
six hundred sixty six
Semoga ini bisa membantu orang lain!
