    Description

      When I alter table from innodb engine to Aria engine, it does not allow the indexes on the virtual columns. I am also unable to add them directly on aria engine with alter table command.

      ALTER TABLE `cases` ADD INDEX(`rthirdref`);

      gives:

      #1904 - Key/Index cannot be defined on a virtual generated column

      `rthirdref` varchar(50) GENERATED ALWAYS AS (reverse(`thirdref`)) VIRTUAL,

      InnoDB engine works fine.
