mysql - How insert in to two table with same auto increment id

Question

I need to insert data from a flat_table into two tables client_data client_contact.

flat_table
    f_name
    l_name
    client_id
    phone
    address

client_data
    id AI
    f_name
    l_name
    ...
    ... 

client_contact
    client_id
    phone
    address
    ...
    ...

I was thinking of using mysql_last_id somehow but I don't know even where to start.

there are other questions like this but they don't answer my question.

Answer 1

1. 假设没有两个客户端共享相同的f_name和l_name：

   INSERT INTO client_data (f_name, l_name)
     SELECT DISTINCT f_name, l_name
     FROM   flat_table;
   
   INSERT INTO client_contact (client_id, phone, address)
     SELECT d.id, f.phone, f.address
     FROM   flat_table f JOIN client_data d USING (f_name, l_name);
   

2. 假设所有记录flat_table对应不同的客户端：

   CREATE TEMPORARY TABLE flat_table2 (
     id SERIAL
   ) SELECT * FROM flat_table;
   
   INSERT INTO client_data (id, f_name, l_name)
     SELECT DISTINCT id, f_name, l_name
     FROM   flat_table2;
   
   INSERT INTO client_contact (client_id, phone, address)
     SELECT id, phone, address
     FROM   flat_table2;
   
   DROP TEMPORARY TABLE flat_table2;
   

3. 如果不同的客户端可能共享相同的记录f_name，l_name但并非每条记录都flat_table对应一个唯一的客户端，则您需要找到某种方法来识别哪些记录对应于哪些客户端。
