INSERT / UPDATE into 2 inner joined table simultaneously

Hi everyone,

This is my first post here.

I have two tables named c and p. When using SELECT, they are linked
using an INNER JOIN like in this example: "SELECT * FROM c INNER JOIN p
ON c.id = p.c_id WHERE name = 'Jones';"

How can I INSERT new rows into both tables simultaneously with
automatically created id numbers, and how can I UPDATE both tables
simultaneously?
