MySQL 外键引用

I m a new bee i have used sql server 2000 before my question is when creating two tables in sql server 2000 say location and projects table projects having a foreign key referencing the location table when inserting values in location the projects is also updated thats is no need to insert the similar value in the foreign key in projects table why is it not possible in mysql when i insert values in location using insert command and when using select command on projects it does not shows the value in foreign key please check the below code

mysql> create table location(
    -> id int not null,
    -> primary key(id))
    -> engine=innodb;
Query OK, 0 rows affected (0.11 sec)


mysql> create table projects(
    -> id int,
    -> location_id int,
    -> foreign key(location_id) references location(id) on update cascade on del
ete cascade)
    -> engine=innodb;
Query OK, 0 rows affected (0.31 sec)


mysql> insert into location values('1')
Query OK, 1 row affected (0.34 sec)

mysql> select * from location;
+----+
| id |
+----+
|  1 |
+----+
1 row in set (0.00 sec)

mysql> select * from projects;
Empty set (0.00 sec)

正如您在上面的代码中看到的那样，在 sql server 2000 中，值可能反映在子表中 为什么在 MySql 中不可能当我在位置表中插入时，项目表会自动选择值并在我查询项目表时在选择查询中显示它

insert into projects values (1,1);
select * from projects;
update location set id = 2 where id = 1;
select * from projects;
