如何将值插入到 mySql 上具有外键关系的两个表中

Question

npas

+-----+------+---------------------------+
| id  | npa  | town                      |
+-----+------+---------------------------+
|   1 |  104 |  Villars-le-terroir       |
+-----+------+---------------------------+

客户

+----+----------+-----------+------------------------+---------------+---------------------------+---------------+--------+
| id | lastname | firstname | address                | phone         | email                     | mobile        | npa_id |
+----+----------+-----------+------------------------+---------------+---------------------------+---------------+--------+
|  1 | Gentizon | Alain     | Derrière le Chateaux 6 | 021 000 00 00 | xxxxx.xxxxxx@xxxxx.com | 077 000 00 00 |     96 |
+----+----------+-----------+------------------------+---------------+---------------------------+---------------+--------+


INSERT INTO customers (lastname,firstname,address,email,mobile) 
VALUES ('xycyxc', 'xcyc', 'xycyxc', 'xycyxcy', 'xycyxc');


INSERT INTO npas (npa,town) 
VALUES ('xycyxcy', 'xycyxc')

我该怎么办？

如果我的问题与其他问题重复，我很抱歉。我比 SQL 更新鲜。感谢您的帮助

Answer 1

INSERT INTO npas (npa, town) 
    VALUES ('npa', 'town');

INSERT INTO customers (lastname, firstname, address, email, mobile, npa_id) 
    SELECT 'lastname', 'firstname', 'address', 'email', 'mobile', npas.id
    FROM npas
    WHERE npas.npa = 'npa' AND npas.town = 'town';
