     `portal_products(main category)`main 
    where sub.product_id=main.product_id ;

使用聯盟或聯盟所有會工作 – Hytool

要將'portal_products（子類別）'描述爲表名的不好選擇，那麼可以低估 – Strawberry

如果我得到你的要求正確

select sub.sub_product_image_path,sub.sub_product_id 
from `portal_products(sub category)` sub 
inner join `portal_products(main category)`main on 
sub.product_id=main.product_id 
where sub.product_id=35;

select sub.sub_product_image_path, sub.sub_product_id 
from `portal_products(sub category)` sub , 
inner join `portal_products(main category)`main on sub.product_id=main.product_id ; 

union all 

select sub.sub_product_image_path, sub.sub_product_id 
from `portal_products(sub category)` sub 
where sub.product_id=35
