将数据从一个表复制到另一个表并添加其他数据

Question

I have a temp table and a regular table in my database. The column name and types are identical, except the regular table has an extra field. I am trying to write a query that copies the information from the temp table into the regular table and adds data into the addition field all in one query.

I understand how to copy columns from one table to another (eg INSERT INTO TABLE 1 (col 1, etc..) SELECT TABLE2), but how do i do this AND then add in a the value for the new field?

Thanks for your help.

Answer 1

 INSERT INTO TABLE1 (col 1, col2,..., the_extra_col) SELECT *, NULL from TABLE2

要么

 INSERT INTO TABLE1 (col 1, col2,..., the_extra_col) SELECT *, the_default_date_here from TABLE2

Answer 2

If you want your values

INSERT INTO TABLE1 (col 1, col2,..., the_extra_col) SELECT *,concat('".$value."') as value1 from TABLE2

Date means just put now() INSERT INTO TABLE1 (col 1, col2,..., the_extra_col) SELECT *,now() from TABLE2
