Question

我有这样的查询：

SELECT products.* FROM products
WHERE products.code = 'search word' OR products.id IN(SELECT product_names.product_id 
                     FROM product_names 
                     WHERE MATCH (product_names.name) 
                     AGAINST ('+search* +word*' IN BOOLEAN MODE) 
                     ORDER BY product_names.sorting_field)
ORDER BY ???

我希望主查询的顺序与WHERE IN()的顺序相同。我似乎无法使用FIELD或FIND_IN_SET，因为我不知道我从MATCH AGAINST获得了什么。

我尝试了ORDER BY FIELD(products.id, product_names.product_id)之类的东西，但我没弄明白如何让它发挥作用。

实际上我的查询更长，更复杂，这是它的一些伪版本。我无法在子查询之外执行MATCH AGAINST。

Answer 1

SELECT   products.*
FROM     products LEFT JOIN (
  SELECT product_id, sorting_field
  FROM   product_names 
  WHERE  MATCH (product_names.name) AGAINST ('+search* +word*' IN BOOLEAN MODE) 
) t ON products.id = t.product_id
WHERE    products.code = 'search word' OR t.product_id IS NOT NULL
ORDER BY t.sorting_field

ORDER BY WHERE IN（子查询）
