从 JOIN Shows #1064 更新表

Question

我正在尝试执行此操作

  UPDATE product
SET Product_entr_notes = t2.note
    ,Product_entr_email = t2.email
    ,Product_entr_mobile = t2.Mobile
    ,Product_entr_phone = t2.Home_Phone
FROM product AS t1
INNER JOIN result AS t2 ON t1.id = t2.ACTID

但我得到了

1064 - 您的 SQL 语法有错误；检查手册 对应于您的 MariaDB 服务器版本，以便使用正确的语法 'FROM product t1 INNER JOIN result t2 ON t1.id = t2.ACTID WHERE 第 1 行的 t1.id = t2.ACTID'

Answer 1

你应该把JOIN放在Update之后，比如：

UPDATE product t1
INNER JOIN result AS t2 ON t1.id = t2.ACTID
SET Product_entr_notes = t2.note
    ,Product_entr_email = t2.email
    ,Product_entr_mobile = t2.Mobile
    ,Product_entr_phone = t2.Home_Phone
