1093 - You can't specify target table 'xxx' for update in FROM clause, Time: 0.002000s

1093 - You can't specify target table 'xxx' for update in FROM clause, Time: 0.002000s

根據結果集在b_order_copy1 表中刪除

DELETE FROM b_order_copy1 WHERE Id in  ( SELECT Id FROM b_order_copy1 WHERE request_counts = 2 AND response_counts = 2 AND final_status = 200 AND create_time BETWEEN 1548000000000 AND 1548086400000  );

會出現1093 - You can't specify target table 'xxx' for update in FROM clause, Time: 0.002000s錯誤。（不能在同一語句中更新select出的同一張表中的屬性值）

mysql是不容許這樣操做的，須要經過一個子查詢的方式獲取到id。update語句同理。

解決方法：

DELETE FROM b_order_copy1 WHERE Id in ( SELECT a.Id FROM ( SELECT Id FROM b_order_copy1 WHERE request_counts = 2 AND 
response_counts = 2 AND final_status = 200 AND create_time BETWEEN 1548000000000 AND 1548086400000 ) AS a );
