Mapping/Renaming column names for MariaDB when using RETURNING *

const insertQuery = this.ctDb
            .insert(someTable)
            .values(opts)
            .getSQL();
insertQuery.append(sql` RETURNING *`);
const execResult = await this.ctDb.execute(insertQuery);
const resultList = execResult[0] as any;
const result = resultList[0] as any;
// For creating this entity I would like to use the mapper
const entity = {
    id: result.id,
    systemName: result.system_name,
};

/*
Exec result looks like this:
[
  [
    {
      id: 96,
      system_name: 'test-24533',
    }
  ],
  [
    `id` INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
    `system_name` VARCHAR(20) NOT NULL UNIQUE_KEY,
  ]
]
