Question

UPDATE wp_posts AS P 
LEFT JOIN wp_postmeta AS Latitude 
ON Latitude.meta_key='lv_listing_lat' AND P.ID=Latitude.post_id 
LEFT JOIN wp_postmeta AS Longtitude 
ON Longtitude.meta_key='lv_listing_lng' AND P.ID=Longtitude.post_id 
SET P.post_status='trash' 


WHERE P.post_type='lv_listing' 
    AND Latitude.meta_value... //duplicate clause 
    AND Latitude.meta_value .... //duplicate clause 

請幫幫我！非常感謝

從WordPress數據庫

這裏這個數據，您可以更新加入條件

UPDATE p SET P.post_status='trash' 
    from p_posts AS P 
    LEFT JOIN wp_postmeta AS Latitude ON Latitude.meta_key='lv_listing_lat' AND P.ID=Latitude.post_id 
    LEFT JOIN wp_postmeta AS Longtitude ON Longtitude.meta_key='lv_listing_lng' AND P.ID=Longtitude.post_id 
    WHERE P.post_type='lv_listing' 

重複行（試試這個不知道它會工作或沒有:)）

UPDATE p SET P.post_status='trash' 
    from p_posts AS P 
    LEFT JOIN wp_postmeta AS Latitude ON Latitude.meta_key='lv_listing_lat' AND P.ID=Latitude.post_id 
    LEFT JOIN wp_postmeta AS Longtitude ON Longtitude.meta_key='lv_listing_lng' AND P.ID=Longtitude.post_id 
    WHERE P.post_type='lv_listing' and Longtitude.meta_value in (Select Longtitude.meta_value from p_posts AS P 
    LEFT JOIN wp_postmeta AS Latitude ON Latitude.meta_key='lv_listing_lat' AND P.ID=Latitude.post_id 
    LEFT JOIN wp_postmeta AS Longtitude ON Longtitude.meta_key='lv_listing_lng' AND P.ID=Longtitude.post_id 
    WHERE P.post_type='lv_listing' group by Longtitude.meta_value having count(Longtitude.meta_value)>1)
