What database server and version is required?
I’m using MariaDB 10.4-ish and getting this error when trying to create demo2023 table with demo2023.sql
MariaDB does not support MySQL 8’s utf8mb4_0900_ai_ci. You may simply remove the comment /*!40100 DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci */ first, or change “utf8mb4_0900_ai_ci” to “utf8mb4_general_ci”.
