mysql은 열 이름으로 인덱스 키워드를 사용합니다.

Question

안녕하세요, 내 프로젝트에서 by 절의 mysql 쿼리에서 index 키워드를 사용해야한다는 요구 사항이 있습니다.

내 쿼리는 다음과 같습니다

 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 

이 쿼리는이 오류 (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")

을주고있다하지만 쿼리에서 ORDER BY 절을 제거 할 때, 그것은 오류를 포기하지 않을거야.

아무도 내 쿼리에 mysql의 index 키워드를 사용하는 방법을 제안 할 수 있습니까?

인덱스는 reserved word입니다. 견적이 (백 틱 포함) :

ORDER BY `index` DESC
