我需要向一个表中添加多个列，但将这些列放置在 一个名为 lastname 的列之后。
我试过这个:
ALTER TABLE `users` ADD COLUMN
(
`count` smallint(6) NOT NULL,
`log` varchar(12) NOT NULL,
`status` int(10) unsigned NOT NULL
)
AFTER `lastname`;
我收到此错误:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') AFTER
lastname' at line 7
如何在这样的查询中使用 AFTER？
最佳答案
试试这个
ALTER TABLE users
ADD COLUMN `count` SMALLINT(6) NOT NULL AFTER `lastname`,
ADD COLUMN `log` VARCHAR(12) NOT NULL AFTER `count`,
ADD COLUMN `status` INT(10) UNSIGNED NOT NULL AFTER `log`;
