推荐答案

这可能对您有帮助

This may help you

Insert into UserDetails(TimeStamp)
select TimeStamp from History

如果要复制所有记录，然后将它们作为新记录插入，则

if you are copying all the record, and inserting them as new then

Insert into UserDetails(TimeStamp)
select TimeStamp from History

但是如果您要从历史记录表中复制并将其插入到现有列中，那么

but if you are copying from history table and inserting them to existing column then

update userDetails set TimeStamp= (select TimeStamp from history where history.userID= UserDetails.UserID)
--modify the condition to your needs,

这不会插入新记录，而只会更新现有记录.

this will not insert records as new, but will only update the existing records.
