多个选择插入

Question

我需要能够为插入设置多个select语句或值。如果我删除第二列名称（notication_timestamp），以下工作。

insert into notification (msg,notification_timestamp) select msg from data;

我希望能够说：

insert into notification (msg,notification_timestamp) values (select msg from data,now());

但这不起作用。有什么想法吗？

Answer 1

删除values语句：

Insert into notification(msg, notification_timestamp)
    Select msg, now()
    from data

Answer 2

您没有将notification_timestamp放在选择查询

上

insert into notification (msg,notification_timestamp) select msg,'value for notification_timestamp' from data;

所以可能

insert into notification (msg,notification_timestamp) select msg,now() from data;
