使用 MySQL 将记录从一张表插入到多张关系表

Question

I have three tables customers , customer_entity , customer_info . I wanted to insert records from customers table to customer_entity and customer_info at same time, but customer_entity tables primary key will be part of customer_info table.

Assumed Code can we write something like this?

INSERT INTO customer_entity (mobile, name)
INSERT INTO customer_info (customer_entity_id,email, name)
SELECT mobile, name, email customers FROM customers

I dont want to use any programming language only MYSQL

Answer 1

This query may help you.

INSERT INTO customer_entity (mobile,email)
SELECT mobile, email FROM customer ORDER BY id ASC;
INSERT INTO customer_info (customer_entity_id, email)
SELECT customer_entity.id, email, (SELECT email FROM customer WHERE mobile= customer_entity.mobile) FROM customer;

Here the customer table is the main table which has data already and we are inserting it into customer_entity table and customer_info table with customer_entity_id .

Answer 2

You can try using SELECT LAST_INSERT_ID() also:

INSERT INTO customer_entity (mobile,email)
INSERT INTO customer_info (LAST_INSERT_ID(), email)

If you insert a record into a table that contains an AUTO_INCREMENT column, you can obtain the value stored into that column by calling the mysql_insert_id() function.
