我有一個奇怪的錯誤

我相信這是與我的外鍵，但我真的不明白什麼是錯。這是我的錯誤：我有一個奇怪的錯誤

「Accounts」表在哪裏？即使它在兩個FK中被引用，你也沒有表「Accounts」。此外，即使您試圖在其上添加FK約束，您在「客戶」表中也沒有列'AccountID'。 –

@MichaelBerkowski這是我的不好，我忘了複製那些代碼，但問題依然存在 –

errno的150是FOREIGN KEY錯誤，通常是由於數據類型不匹配或丟失柱。就你而言，它是表名中的拼寫錯誤。

你必須在Accounts FK定義不正確的表名AccountTypes而不是AccountType：

FOREIGN KEY (`AccountType`) REFERENCES AccountTypes(`AccountType`) 
-------------------------------------------------^^^ Oops, should be AccountType

還有更遠線，Customers表將在下一個失敗，因爲沒有AccountID列：

CREATE TABLE `Customers` (
    `CustomerID` int(11) NOT NULL DEFAULT '0', 
    `CustomerFirstName` varchar(255) NOT NULL, 
    /* Add the AccountID column for your FK definition */ 
    `AccountID` INT(10), 
    `CustomerLastName` varchar(255) NOT NULL, 
    `Address` varchar(255) NOT NULL, 
    `Email` varchar(255) NOT NULL, 
    `Flag` varchar(1) NOT NULL, 
    PRIMARY KEY (`CustomerID`), 
    FOREIGN KEY (`AccountID`) REFERENCES Accounts(`AccountID`) 
);

稍微還有一點，您會遇到問題，因爲的的AccountID不匹配Accounts.AccountID這是INT(10)：

CREATE TABLE `CustomerAccounts` (
    `CustomerID` int(11) NOT NULL DEFAULT '0', 
    /* Make this INT(10) to match the referenced column */ 
    `AccountID` int(10) DEFAULT '0', 
    FOREIGN KEY (`AccountID`) REFERENCES Accounts(`AccountID`), 
    FOREIGN KEY (`CustomerID`) REFERENCES Customers(`CustomerID`) 
);
