insert related data into two tables

Hello,

I have two tables like these:

TABLE_1: people registry
fields: ID_T1, SURNAME, NAME
ID_T1 is primary key

TABLE_2: work groups
fields: ID_T2, TASK
ID_T2 is foreign key related to ID_T1

the first table is the list of employees, the second the task.

Sometime I need to insert a new employee and at the same time the task
for him:
I want to INSERT TO table 1 JOHN DOE (the ID is assigned automatically
since it's a primary key) and INSERT TO table 2 the ID and the task
name for JOHN DOE. Is it possible to create a single query? What is the
best way to do this?

Thanks,

Filippo
