Mysql使用索引關鍵字作爲列名

Question

嗨，在我的項目中，我有一個要求，在子句中按順序在mysql查詢中使用索引關鍵字。

我的查詢看起來是這樣的：

 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 

此查詢給這個錯誤(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")

但是當我by子句從查詢中刪除訂單，它不給任何錯誤。

任何人都可以請建議如何在我的查詢中使用mysql的index關鍵字？

索引是reserved word。引用它（與反單引號）：

ORDER BY `index` DESC
