Mysql insert into 2 tables

Question

I want to make a insert into 2 tables

visits:

visit_id int | card_id int

registration:

registration_id int | type          


        

Answer 1

It seems like the problem you are trying to solve is to get the auto-increment value from the "visits" row to insert into "registration". Am I right?

If so, you can just use the LAST_INSERT_ID() function like this:

INSERT INTO `visits` (`visit_id`,`card_id`) 
VALUES (NULL, 12131141);
INSERT INTO `registration` (`registration_id`, `type`, `timestamp`, `visit_id`) 
VALUES (NULL, 'in', UNIX_TIMESTAMP(), LAST_INSERT_ID());
