mysql中DATE默认值

mysql中DATE默认值,第1张

更新,在stackoverflow上找到了8.0.13版本的解决方案: 链接

经过查看官网,发现5.7版本: 链接

With one exception, the default value specified in a DEFAULT clause  must be a literal constantit cannot be a function or an expression . This means, for example, that you cannot set the default for a date column to be the value of a function such as NOW() or CURRENT_DATE . The exception is that, for TIMESTAMP and DATETIME columns, you can specify CURRENT_TIMESTAMP as the default. See Section 11.2.6, “Automatic Initialization and Updating for TIMESTAMP and DATETIME” .

创建表的时候,想为DATE类型设定默认值当前日期。发现一直报错,百度没有什么好办法。

在sqlserver2000中可以这样

create table test(name varchar(10),registerTime datetime default getdate())

设置默认值。但在MySQ中

create table test(name varchar(10),registerTime datetime default now())

ERROR 1064: You have an error in your SQL syntax. Check the manual that corresp

onds to your MySQL server version for the right syntax to use near 'now()
