mysql 聚合函数排序不正确

Question

我对排序依据的聚合函数有疑问。问题是输出排序不正确。甚至可以按顺序聚合函数？他们每次都为我工作...

(problem is somewhere in order by MIN() function).

我尝试将所有变量转换为相同的数据类型，但效果不佳。

查询：

SELECT SQL_CALC_FOUND_ROWS
  COALESCE(MIN(IF(FIND_IN_SET("O", p.campaign), NULL, p.price) * (1 + v.vat / 100) * (1 - p.discount / 100)), p.price) as test,
  p.id as `id`

FROM
  products p
  LEFT JOIN products_variations pv ON p.id = pv.id_product
  LEFT JOIN photos_products_relation ppr ON p.id = ppr.id_product AND ppr.show_in_lead = 'Y'
  LEFT JOIN producers pr ON p.producer = pr.id
  INNER JOIN products_in_sections ps ON p.id = ps.id_product
  INNER JOIN vats v ON p.vat = v.id

WHERE ((pv.figure = 'Y') OR (pv.figure IS NULL)) AND (pr.active = 'Y' OR pr.id IS NULL) AND (
  ((COALESCE(pv.in_store, p.in_store) > 0) AND (ps.id_section IN (1868, 1855, 1758, 1746, 1875, 1947, 1870, 1952, 1895, 1942, 1737, 1741, 1744, 1828, 1887, 1762, 1773, 1893, 1781, 1897, 1929, 1920, 1896, 1908, 1751, 1775, 1782, 1770, 1778)) AND (p.figure = 'Y') AND
   (NOT FIND_IN_SET('O', coalesce(pv.campaign, '')))) AND (1)) AND (p.id_model IS NOT NULL)
GROUP BY p.id_model
ORDER BY COALESCE(MIN(IF(FIND_IN_SET("O", p.campaign), NULL, p.price) * (1 + v.vat / 100) * (1 - p.discount / 100)), p.price) ASC
LIMIT 36 OFFSET 0;

输出：

如您所见，列 test 排序不正确...

通常我会做

ORDER BY test

可行，但我不想在输出中显示字段 'test'。

（原始查询有更多 select 个字段）。

感谢您的回答:)

我不知道为什么它不起作用，我看不出有什么问题。如果必须的话，你可以随时做这样的事情。

SELECT ... (All columns but test)
FROM (  your query here as subquery) a
ORDER BY test ASC
