根据关系 table 的值从另一个 table 中选择

Question

我在 MySQL 中有三个 table:

1) bank_accounts

- accounts_id (PRIMARY)
- accounts_account_number (UNIQUE)

2) bank_accounts_customers

- accounts_customers_id (PRIMARY)
- accounts_customers_account_id (INDEX)
- accounts_customers_customer_id (INDEX)

3) bank_customers

- customers_id (PRIMARY)
- customers_customer_number (UNIQUE)
- customers_title
- customers_first_name
- customers_middle_name
- customers_last_name

我需要获取存储在 bank_accounts table 中的帐号和存储在 [=52 中的客户编号=]table。 table bank_accounts_customers 在客户和他们拥有的帐户之间存储了一个 link，因此多个客户可以共享一个帐户。数据库中的所有 table 都已编入索引并使用外键 link 它们。

我不确定 INNER JOIN 或 JOIN 是否有效以及如何执行此操作？

我试过的查询是：

SELECT `bank_accounts`.`accounts_account_number`, `bank_customers`.`customers_customer_number`
FROM `bank_accounts`, `bank_customers`
INNER JOIN `bank_accounts_customers`
ON bank_accounts_customers`.`accounts_customers_account_id` = `bank_accounts`.`accounts_id`

Answer 1

select 
ba.accounts_account_number, 
bc.customers_title,bc.customers_first_name, bc.customers_middle_name, bc.customers_last_name 
from bank_accounts ba inner join bank_accounts_customers bac 
on ba.accounts_id = bac.accounts_customers_account_id 
inner join bank_customers bc 
on bac.accounts_customers_customer_id = bc.customers_id

试试这个..!!

Answer 2

SELECT ba.accounts_account_number, bc.customers_customer_number 
FROM bank_accounts AS ba

INNER JOIN bank_accounts_customers AS bac
 ON bac.accounts_customers_account_id = ba.accounts_id

INNER JOIN bank_customers AS bc
 ON bc.customers_id = bac.accounts_customers_customer_id

应有尽有

Answer 3

试试这个

SELECT ba.accounts_account_number, bc.customers_customer_number 
FROM bank_accounts_customers bac
INNER JOIN bank_accounts ba on bac.accounts_customers_account_id = ba.accounts_id
INNER JOIN bank_customers bc on bac.accounts_customers_customer_id = bc.customers_id
