SQl,UPDATE INNER JOIN 您的 SQL 语法有误

Question

UPDATE A set A.amount = A.amount 
FROM product_in_stock AS A 
INNER JOIN move_str_start AS B ON A.id_model = B.id_model 
WHERE B.id_move=121 AND A.id_stock=7;

我有错误：

You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'FROM product_in_stock AS A INNER JOIN move_str_start AS B ON A.id_model = B.id_m' at line 1

Answer 1

update product_in_stock AS A 
INNER JOIN move_str_start AS B ON A.id_model = B.id_model 
SET A.amount=A.amount+B.count  
WHERE B.id_move=121 AND A.id_stock=7;

PS 这是答案
