我在这里有一个 var_dumped 查询，它显示了错误的结果。

select p.*
, case when p.specials_new_products_price >= 0.0000 
  and (p.expires_date > Now() or p.expires_date IS NULL) 
  and p.status != 0 then 
      p.specials_new_products_price 
  else 
      p.products_price 
end price 

from wp_global_products_table p 
INNER JOIN wp_blogs s ON s.blog_id = p.blog_id 
where p.products_name like '%indifi%' 
or p.products_description like '%indifi%' 
and s.countries_id = '168' 
and global_category_id = '15' 
and p.display_product = '1' 
and p.products_status = '1' 
order by p.products_date_added DESC, p.products_name"

这是原始查询。

$catglobal_sql = "select p.*, case when p.specials_new_products_price >= 0.0000 and (p.expires_date > Now() or p.expires_date IS NULL or p.expires_date ='0000-00-00 00:00:00') and p.status != 0 then p.specials_new_products_price else p.products_price end price from ".TABLE_GLOBAL_PRODUCTS." p INNER JOIN ".TABLE_STORES." s ON s.blog_id = p.blog_id where MATCH (p.products_name,p.products_description) AGAINST ('%".$search_key."%') ".$country_q." ".$zone." ".$currency_type." ".$search_cat." and p.display_product = '1' and p.products_status = '1' ".$duration." ".$product_type." ".$price_range." order by p.products_date_added DESC, p.products_name";
if (!mysql_num_rows(mysql_query($catglobal_sql))) {
$catglobal_sql = "select p.*, case when p.specials_new_products_price >= 0.0000 and (p.expires_date > Now() or p.expires_date IS NULL) and p.status != 0 then p.specials_new_products_price else p.products_price end price from ".TABLE_GLOBAL_PRODUCTS." p INNER JOIN ".TABLE_STORES." s ON s.blog_id = p.blog_id where p.products_name like '%".$search_key."%' or p.products_description like '%".$search_key."%' ".$country_q." ".$zone." ".$currency_type." ".$search_cat." and p.display_product = '1' and p.products_status = '1' ".$duration." ".$product_type." ".$price_range." order by p.products_date_added DESC, p.products_name";
}

说，我搜索数据库上可用的“Indifi”，Indifi 的global_category_id值为 3。

正如您在 var_dumped 结果中看到的那样，它global_category_id是 15，因此不应显示“Indifi”，但确实如此。

我的查询应该是什么问题？

尝试在此处使用括号：

...where (p.products_name like '%indifi%' 
or p.products_description like '%indifi%')
and s.countries_id = '168'
...

这样你们就不会OR在一起太多了。

where p.products_name like '%indifi%' OR p.products_description like '%indifi%' and s.countries_id = '168' and global_category_id = '15' and p.display_product = '1' and p.products_status = '1'

我在那里看到一个OR，所以如果p.products_name like '%indifi%'，那么它是什么都没关系global_category_id。

要确定优先级，请使用括号(... OR ...)。
