将行复制到另一个表并创建新的时间戳

Question

In MySQL, I would like to copy data from my users_temp table to my users_final table. The fields are identical.

Here comes my query:

INSERT users_final (username, password, email)
  SELECT username, password, email)
  FROM users_temp
  WHERE id=8

My users_final table also contains a field "stamp_created".

How do I achieve that when I copy my row from users_temp to users_final the field "stamp_created" of the newly created row will contain the current timestamp?

(Of course I do not want to copy the "stamp_created" value from my users_temp table.)

Answer 1

You can get the current date from the NOW() function . Something like this:

INSERT users_final (username, password, email, stamp_created)
  SELECT username, password, email, NOW()
  FROM users_temp
  WHERE id=8

Answer 2

您可以将CURRENT_TIMESTAMP设置为默认值，并将users_final表中的stamp_created字段设置为不可为空。
