SQL INSERT，也许内部连接

Question

我有这样的INSERT：

INSERT INTO gamecodes (gamecode, accountname, premium_points, alreadyused) 
VALUES ('$gamecode','$accountorname',$premiumpoints,'N') 

我需要帮助。在变量$ accountorname我得到了一个PLAYER的名字，我需要得到他的账户。

两个表：

TABLE PLAYERS 
id, name, account_id.. 
id, player name, table accounts.id 

TABLE ACCOUNTS 
id, name .. 
id = table players account_id 

Answer 1

你可以尝试沿着线的东西：

INSERT INTO gamecodes (gamecode, accountname, premium_points, alreadyused) 
SELECT '$gamecode',accounts.name,$premiumpoints,'N' 
FROM accounts 
JOIN players 
ON accounts.id = players.account_id 
WHERE players.name = '$accountorname' 

Answer 2

您的查询可能看起来像 -

INSERT INTO gamecodes(gamecode, accountname, premium_points, alreadyused) 
VALUES('$gamecode', '$accountname', $premiumpoints, 'N') 
WHERE(SELECT accountname FROM accounts JOIN gamecodes ON accounts.accountname = gamecodes.accountname WHERE accounts.accountname = $accountname)
