LAST_INSERT_ID() MySQL

Question

I have a MySQL question that I think must be quite easy. I need to return the LAST INSERTED ID from table1 when I run the following MySql query:

INSERT INTO          


        

Answer 1

For last and second last:

INSERT INTO `t_parent_user`(`u_id`, `p_id`) VALUES ((SELECT MAX(u_id-1) FROM user) ,(SELECT MAX(u_id) FROM user  ) );
