错误1093.您无法在FROM子句中指定目标表'ps_order_history'进行更新

Question

我一直在寻找，但我仍然不明白为什么它是错误的。我检查了子查询，他们只返回1行。

UPDATE ps_order_history 

SET id_order_state = 18 

WHERE id_order = 
(
    SELECT max(p.id_order) 
    FROM ps_orders p 
    INNER JOIN ps_order_detail d ON d.id_order = p.id_order 
    INNER JOIN ps_order_history oh ON oh.id_order = p.id_order 
    WHERE d.product_name = "Academia Mastermaq" 

    AND p.id_customer = 
    (
     SELECT id_customer 
     FROM ps_customer 
     WHERE firstname = "Cristiano" 
     AND lastname = "Ferreira dos Santos" 
     LIMIT 1 
    ) 
) 

Error Code: 1093. You can't specify target table 'ps_order_history' 
for update in FROM clause 

谢谢！

Answer 1

现在我知道我无法在子查询中加入我的更新表。感谢Marc B！

UPDATE ps_order_history h 
INNER JOIN ps_order_detail d ON d.id_order = h.id_order 

SET h.id_order_state = 15 

WHERE d.product_name = "Academia Mastermaq" 
AND h.id_order = 
(
    SELECT max(p.id_order) 
    FROM ps_orders p 
    /*INNER JOIN ps_order_detail d ON d.id_order = p.id_order 
    INNER JOIN ps_order_history oh ON oh.id_order = p.id_order*/ 


    WHERE p.id_customer = 
    (
     SELECT id_customer 
     FROM ps_customer 
     WHERE firstname = "Cristiano" 
     AND lastname = "Ferreira dos Santos" 
     LIMIT 1 
    ) 
)
