mysql 有没有办法按日期和时间自动递增？
所以说我有一张桌子
mytable
=====================================================
= Comment_ID = First_Name = Comment = DateTime =
=====================================================
= 1 = Bob = FooBar = 11-01-14 11:00 =
= 2 = Jack = Blah = 11-01-14 12:29 =
= 3 = John = jonny = 12-01-14 07:09 =
=====================================================
有没有办法让日期自动递增？
在 MySQL 中运行：
ALTER TABLE `mytable`
CHANGE COLUMN `DateTime` `DateTime` TIMESTAMP NULL DEFAULT CURRENT_TIMESTAMP ;
这会将您的默认值设置为CURRENT_TIMESTAMP.
