查询错误 (1066)：不唯一 table/alias：'useraccounts'

Question

我想从用户那里获取电子邮件和密码 table 其中电子邮件是主键，而对于电子邮件，我想从用户帐户中获取余额和帐户 ID，其中帐户 ID 是外键。针对那个外键，我想要来自 table accounts

的 accountNo

SELECT `user`.`email`, `user`.`passwrd`, `useraccounts`.`Balance`, `useraccounts`.`AccountID`, `accounts`.`AccountNo`
FROM `user` , `accounts`
LEFT JOIN `useraccounts` ON `user`.`email` = `useraccounts`.`email` 
LEFT JOIN `useraccounts` ON `accounts`.`AccountID` = `useraccounts`.`AccountID` 

SELECT `user`.`email`, `user`.`passwrd`, `useraccounts`.`Balance`, `useraccounts`.`AccountID`, `accounts`.`AccountNo`
FROM `user` , `accounts`
LEFT JOIN `useraccounts` ON `user`.`email` = `useraccounts`.`email` 
LEFT JOIN `useraccounts` ON `accounts`.`AccountID` = `useraccounts`.`AccountID`

错误是 #1066- 不唯一 Table/Alias : useraccountsenter image description here
