示例1: fetchPhotoDetail

const [ tags, versions ] = await Promise.all([
DB().queryColumn<string>('title', 'select title from tags where id in (select tag_id from photos_tags where photo_id = ?) order by slug', photoId),
DB().query<VersionType>('select * from versions where photo_id = ? order by version', photoId)

return { tags, versions } as PhotoDetail
// TODO
//const lastVersion = photo.versions[photo.versions.length - 1]
//photo.non_raw = lastVersion.output || photo.non_raw
