Question

I have a table called Users that has the identifier called IdUser that is INT and AI.
I have another table called Subscription that has the foreign key called IdUser that is connected with the primary key of the table Users.

Now, the problem that I have is:
If when I insert a row in the table Users I would like to insert also a row in the subscription table, how can I do?

insert into users (nome, cognome, ...) values ('x', 'y', ...)
insert into subscription (...,IdUser) values (..., ????)

thanks in advance!

Answer 1

for mysql

insert into users (nome, cognome, ...) values ('x', 'y', ...);
insert into subscription (...,IdUser) values (...,LAST_INSERT_ID());
