Answer 1

このライン 'PF' というエラー...

LEFT JOIN oc_product_filter pf ON (p2c.product_id = pf.product_id) 

...株式表の別名をこの行で...

INNER JOIN `oc_product_filter` AS `pf` ON `p2c`.`product_id` = `pf`.`product_id` 

これは起こりません。したがって、別のエイリアスを2番目のエイリアスに付けてください。

SELECT COUNT(DISTINCT product_id) total 
FROM 
    (SELECT DISTINCT p.product_id 
       FROM oc_category_path cp

       JOIN oc_product_filter pf 
        ON pf.product_id = p2c.product_id
