An error occurs when you use a stored function saved in another database in a virtual column.

CREATE TABLE `tbl_test` (
`id` int(0) AS () NOT NULL,
`name` varchar(255) NULL,
PRIMARY KEY (`id`)
);


ALTER TABLE `tbl_test`
ADD COLUMN `name2` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci GENERATED ALWAYS AS (convert_data(name, other_database.stored("sample1", "sample2", "sample3", "sample4", "sample5" , "item_char1")) VIRTUAL NULL AFTER `name`

But

SHOW TABLE STATUS

/var/lib/mysql/mysql-error.log
2018-12-14T14:16:45.399156+09:00 137 [ERROR] /usr/sbin/mysqld: ファイル './database/tbl_test.frm' 内の情報が不正です。

エラー: 1033 SQLSTATE: HY000 (ER_NOT_FORM_FILE)

Error number: 1033; Symbol: ER_NOT_FORM_FILE; SQLSTATE: HY000

How can I delete the last added virtual column or remove the illegally loaded frm file from the database?
