Mysql使用index关键字作为列名

Question

嗨,在我的项目中,我需要在order by子句的mysql查询中使用index关键字.

我的查询如下所示:

     SELECT asset.id, day_part.category, asset.site_id, site.name,
            environment.category_1, environment.category_2, county.town, county.county,
            site.site_id as siteid, media_owner.contractor_name,
            IF (audience_category.impact IS NULL, 0, audience_category.impact) as impact,
            tv_region.id as tv_region_id,
            metropolitan.id as metropolitan_id,
            IF (
                price.price_site = -1,
                IF(
                    price.price_tv_region = -1,
                    price.price_nation,
                    price.price_tv_region
                ),
                price.price_site
            ) AS price,
            format.name AS format,
            format.id AS format_id
        FROM asset
        JOIN site ON asset.site_id = site.id
        JOIN day_part ON asset.day_part_id = day_part.id
        JOIN media_owner ON site.media_owner_id = media_owner.id
        JOIN area ON site.area_id = area.id
        JOIN environment ON site.environment_id = environment.id
        JOIN price ON site.price_id = price.id
        JOIN postcode ON site.postcode_id = postcode.id
        JOIN county ON postcode.county_id = county.id
        JOIN tv_region ON postcode.tv_region_id = tv_region.id
        JOIN metropolitan ON postcode.metropolitan_id = metropolitan.id
        LEFT JOIN temp_media_index_1395751552 as audience_category
            ON audience_category.site_id = site.id
        JOIN frame_grouped ON frame_grouped.site_id = site.id
        JOIN format ON frame_grouped.format_id = format.id
        WHERE frame_grouped.format_id = 3

        ORDER BY index DESC
        LIMIT 100 OFFSET 0

此查询提供此错误 (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'index DESC\n LIMIT 100 OFFSET 0' at line 35")

但是当我从查询中删除order by子句时,它没有给出任何错误.

任何人都可以建议如何index在我的查询中使用mysql 的关键字？

索引是保留字.引用它(带背蜱):

ORDER BY `index` DESC
