mysql - 如何将 MySQL 日期(时间戳)字段设置为默认值

Question

我已经尝试过

alter table t_granja ALTER COLUMN purchase_date TIMESTAMP DEFAULT now();

但我收到一个错误

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 'TIMESTAMP DEFAULT now()' at line 1

Answer 1

使用CURRENT_TIMESTAMP

ALTER TABLE t_granja 
ALTER COLUMN purchase_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP;
