在MySQL触发器中将整个表从一个表复制到另一个表

Question

I have two tables with identical schemas, I want to copy the newly inserted record from table1 to table2 in a trigger, my code is below and works, but only copies the id field

BEGIN
   insert into Table2 (id) values (new.id);
END

However the table many columns, is there a way to copy the entire record into the table2 without specifying all the columns and values, like below

BEGIN
   insert into Table2 SELECT * FROM NEW;
END

Thanks

Answer 1

Your second SQL is fine but you have to do one query first for using the star in your select into :

SET IDENTITY_INSERT NEW ON

And then :

BEGIN
   insert into Table2 SELECT * FROM NEW;
END

And dont forget to put it OFF at the end

EDIT 1

If it's not working, maybe try to put some priority on your sql :

INSERT INTO `Table2` (SELECT * FROM `NEW`);

EDIT 2

If it's still not working, maybe you could try to create the table with all the element directly :

CREATE TABLE Table2 [AS] SELECT * FROM NEW;

Answer 2

这有效

  insert into Table2 SELECT * FROM Table1 where id=new.id;
