Question

我试图更新一个名为visit_date的列，其中id应该是propId，但似乎不可能在SQL phpMyAdmin中这样做。

我需要编辑总共500 000行，其中一些列在下面：

UPDATE `property_visit` SET (`propId`, `visit_date`) VALUES
(89, '22-01-2018'),
(89, '22-01-2018'),
(89, '22-01-2018'),
(89, '22-01-2018'),
(89, '22-01-2018'),
(89, '22-01-2018'),
(89, '22-01-2018'),
(89, '22-01-2018'),
(89, '22-01-2018'),
(89, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(118, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(109, '22-01-2018'),
(121, '22-01-2018');

Answer 1

你可以使用INSERT ... ON DUPLICATE KEY UPDATE，我假设你使用的是MySQL数据库。类似于here
