MySQL: How to insert a record for each result in a SQL query?

Question

Say I have a select

SELECT DISTINCT id, customer_id, domain FROM config WHERE type = \'foo\';

which returns some records.

How can I do

Answer 1

EDIT- After reading comment on @Krtek's answer.

I guess you are asking for an update instead of insert -

update config set domain = 'www.example.com'

This will update all existing records in config table with domain as 'www.example.com' without creating any duplicate entries.

OLD ANSWER -

you can use something like -

INSERT INTO config (id, customer_id, domain)
select id, customer_id, domain FROM config

Note:- This will not work if you have id as primary key
