如何进行多重删除查询

Question

大家好，我对此查询有疑问;

DELETE FROM 
 our_work, 
 our_work_images, 
 our_work_portf_img
WHERE 
 our_work.id = 6
AND 
 our_work_portf_img.portf_id = 6
AND
 our_work_portf_img.img_id = our_work_images.img_id;

我想删除第一个表“our_work”中的所有关系，我的对表名为“our_wrok_porft_img”，我的图像表“our_work_images”

EDIT;

我通过在外键上添加级联来解决问题

DELETE FROM our_work WHERE our_work.id = 1;
