Question

我有一个搜索功能，可以根据输入搜索mysql结果。现在我想在where子句中包含来自不同表格的结果的count（）。

喜欢这个场景。 I want to search "Dog" where count(like_id) >= 1.

我想要包括的喜欢表格是：TABLE_GLOBAL_LIKES。

TABLE_GLOBAL_LIKES的结构是：字段：like_id，user_id，products_id，blog_id。

两个TABLE_GLOBAL_PRODUCTS和TABLE_GLOBAL_LIKES共有一个products_id和blog_id的公共字段。

这是我的工作查询，我希望包含Likes表。

SELECT SQL_CALC_FOUND_ROWS p.*,
       CASE
           WHEN p.specials_new_products_price > 0.0000
                AND (p.expires_date > Now()
                     OR p.expires_date IS NULL
                     OR p.expires_date ='0000-00-00 00:00:00')
                AND p.status != 0 THEN p.specials_new_products_price
           ELSE p.products_price
       END price
FROM ".TABLE_GLOBAL_PRODUCTS." p
INNER JOIN ".TABLE_STORES." s ON s.blog_id = p.blog_id
WHERE MATCH (p.products_name,
             p.products_description) AGAINST ('*".$search_key."*')
  AND p.display_product = '1'
  AND p.products_status = '1' HAVING price <= ".$priceto_key."
  AND price >= ".$pricefrom_key."
ORDER BY p.products_date_added DESC, p.products_name

我是mysql查询的新手..请帮忙。

试试这个：

SELECT SQL_CALC_FOUND_ROWS p.*, COUNT(l.like_id)
       CASE
           WHEN p.specials_new_products_price > 0.0000
                AND (p.expires_date > Now()
                     OR p.expires_date IS NULL
                     OR p.expires_date ='0000-00-00 00:00:00')
                AND p.status != 0 THEN p.specials_new_products_price
           ELSE p.products_price
       END price
FROM ".TABLE_GLOBAL_PRODUCTS." p
INNER JOIN ".TABLE_STORES." s ON s.blog_id = p.blog_id
INNER JOIN ".TABLE_GLOBAL_LIKES." l ON l.blog_id = p.blog_id AND l.products_id = p.products_id
WHERE MATCH (p.products_name,
             p.products_description) AGAINST ('*".$search_key."*')
  AND p.display_product = '1'
  AND p.products_status = '1' HAVING price <= ".$priceto_key."
  AND price >= ".$pricefrom_key."
GROUP BY p.products_id
HAVING COUNT(l.like_id)>0
ORDER BY p.products_date_added DESC, p.products_name

count（）来自不同表的where子句
