Mysql 同一表上的多个联接

我的模式是

CREATE TABLE IF NOT EXISTS `account` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(120) NOT NULL,
   PRIMARY KEY (`id`)
 ); 

 CREATE TABLE IF NOT EXISTS `reseller_did` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `phone` int(11) NOT NULL,  
  `superadmin_id` int(11) NOT NULL DEFAULT '0',
  `reseller_id` int(11) NOT NULL DEFAULT '0',
  `admin_id` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`),
  FOREIGN KEY (`superadmin_id`) REFERENCES account(`id`),
  FOREIGN KEY (`reseller_id`) REFERENCES account(`id`),
  FOREIGN KEY (`admin_id`) REFERENCES account(`id`)
) 

我想找到他们的超级管理员，经销商，管理员姓名的电话。问题是我不能在同一id上多次加入。我尝试过的查询

select phone,superadmin_id,reseller_id, admin_id, name from reseller_did join 
account on account.id=reseller_did.admin_id 

上面的查询通过加入admin_id来显示admin name，但是如何获取同一手机的superadmin name和经销商name

编辑：样本输入

科目表

id     name

3      SuperAdmin1
9      Reseller1
10     Admin1

经销商(你做过

id  phone        superadmin_id   reseller_id   admin_id

1   9090909090   3                 9             10

样本输出

phone        superadmin    reseller    admin

9090909090   SuperAdmin1  Reseller1   Admin1

试试这个；）

或

在这个问题上，这个sql应该感谢

希望这能奏效

select 
    rd.phone as Phone ,
    a.name as Superadmin,
    a1.name as Reseller,
    account.name as Admin
from
    reseller_did rd
        join
    account ON account.id = rd.admin_id
        join
    account a ON a.id = rd.superadmin_id
        join
    account a1 ON a1.id = rd.reseller_id

您可以创建

帐户

表的三个别名，并将它们与

分销商(u did

表)进行内部连接

SELECT 
R.id,
R.phone,
A1.name AS superadmin,
A2.name AS reseller,
A3.name AS admin
FROM reseller_did R
INNER JOIN account A1 ON R.superadmin_id = A1.id 
INNER JOIN account A2 ON R.reseller_id = A2.id
INNER JOIN account A3 ON R.admin_id = A3.id ;

替代方法：

如果不想采用内部联接，可以使用以下查询获得相同的结果

SELECT 
R.phone,
(SELECT name FROM account WHERE id = R.superadmin_id) AS SuperAdmin,
(SELECT name FROM account WHERE id = R.reseller_id) AS Reseller,
(SELECT name FROM account WHERE id = R.admin_id) AS Admin
FROM reseller_did R;

注意：您正在

INT

数据类型中存储电话号码。您不应该使用

INT

存储电话号码。相反，您应该使用

VARCHAR

请发布一些示例输入和基于此的预期输出。@1000111我的错误，更新了与post类似的问题

SELECT 
R.id,
R.phone,
A1.name AS superadmin,
A2.name AS reseller,
A3.name AS admin
FROM reseller_did R
INNER JOIN account A1 ON R.superadmin_id = A1.id 
INNER JOIN account A2 ON R.reseller_id = A2.id
INNER JOIN account A3 ON R.admin_id = A3.id ;

SELECT 
R.phone,
(SELECT name FROM account WHERE id = R.superadmin_id) AS SuperAdmin,
(SELECT name FROM account WHERE id = R.reseller_id) AS Reseller,
(SELECT name FROM account WHERE id = R.admin_id) AS Admin
FROM reseller_did R;
