我有一个奇怪的错误

我相信这是与我的外键，但我真的不明白什么是错。这是我的错误：我有一个奇怪的错误

“Accounts”表在哪里？即使它在两个FK中被引用，你也没有表“Accounts”。此外，即使您试图在其上添加FK约束，您在“客户”表中也没有列'AccountID'。 –

@MichaelBerkowski这是我的不好，我忘了复制那些代码，但问题依然存在 –

errno的150是FOREIGN KEY错误，通常是由于数据类型不匹配或丢失柱。就你而言，它是表名中的拼写错误。

你必须在Accounts FK定义不正确的表名AccountTypes而不是AccountType：

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

还有更远线，Customers表将在下一个失败，因为没有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`) 
);

稍微还有一点，您会遇到问题，因为的的AccountID不匹配Accounts.AccountID这是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`) 
);
