多个选择插入

Question

我需要能够为我的插入有多个选择语句或值。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()); 

但是，这并不工作。有任何想法吗？

Answer 1

你没有把notification_timestamp上选择查询

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

因此，它可能

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

Answer 2

取出值声明：

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