Duplicate / Copy records in the same MySQL table

Question

I have been looking for a while now but I can not find an easy solution for my problem. I would like to duplicate a record in a table, but of course, the unique primary key

Answer 1

The way that I usually go about it is using a temporary table. It's probably not computationally efficient but it seems to work ok! Here i am duplicating record 99 in its entirety, creating record 100.

CREATE TEMPORARY TABLE tmp SELECT * FROM invoices WHERE id = 99;

UPDATE tmp SET id=100 WHERE id = 99;

INSERT INTO invoices SELECT * FROM tmp WHERE id = 100;

Hope that works ok for you!
