Answer 1

You have to use SCOPE_IDENTITY to get the last inserted IDENTITY value:
use tempdb;
go
create table person(
id int not null identity(1,1) primary key,
name varchar(50),
modified_date datetime default (CURRENT_TIMESTAMP)
create table books(
id_book int not null identity primary key,
id_person int,
title varchar(250),
modified_date datetime default (CURRENT_TIMESTAMP)
go
declare @bb as INT;
insert into person (name) values ('John');
set @bb = SCOPE_IDENTITY();
insert into books (id_person,title) values (@bb,'The story of my life');
go
select * from person; select * from books;
go
id name modified_date
1 John 2014-06-23 08:49:27.170
id_book id_person title modified_date
1 1 The story of my life 2014-06-23 08:49:27.170
The other way is to use the OUTPUT clause:
