Incompatibility with Mysql 5.7(Expression #1 of ORDER BY clause is not in SELECT list)

Question

When I execute the following query I receive an Exception:

Error Code: 3065 Expression #1 of ORDER BY clause is not in SELECT list, references column 'webstore.level_depth' which is not in SELECT list; this is incompatible with DISTINCT

My Query:

SELECT DISTINCT c.id_parent, c.id_category, cl.name, cl.description, cl.link_rewrite
FROM `pj_category_shop` cs, `pj_category` c
INNER JOIN `pj_category_lang` cl ON (c.`id_category` = cl.`id_category` AND cl.`id_lang` = 1 AND cl.id_shop = 2 )
WHERE (c.`active` = 1 OR c.`id_category` = 2)
  AND cs.`id_category` = c.`id_category`
  AND cs.`id_shop` = 2
  AND c.`id_category` != 1
  AND `level_depth` <= 2
  AND c.id_category IN (
    SELECT id_category
    FROM `pj_category_group`
    WHERE `id_group` IN (3)
  )
ORDER BY `level_depth` ASC, cl.`name` ASC;

Why is this happening?

Answer 1

I have find the answer for my question.Actually mysql 5.7 contains 'ONLY_FULL_GROUP_BY' in sql mode.So we can't perform orderby in the element that is not in select list.we have to change it from

'ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION' 

into

'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'

We can done this by executing the following queries

SET SESSION sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'

SET GLOBAL sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'
