Mysql的正向工程錯誤號150

Question

我建模使用MySQL工作臺CE EER建模我的數據庫瑪，現在我被困在與MySQL錯誤號150

我的SQL代碼：

CREATE TABLE `myschema`.`Clients` (
    `phone` VARCHAR(15) NOT NULL , 
    `surname` VARCHAR(30) NOT NULL , 
    `name` VARCHAR(30) NOT NULL , 
    `middleName` VARCHAR(30) NULL , 
    `discountCardNumber` BIGINT NULL , 
    PRIMARY KEY (`phone`) , 
    UNIQUE INDEX `discountCardNumber_UNIQUE` (`discountCardNumber` ASC) , 
    CONSTRAINT `fk_Clients_DiscountCards1` 
    FOREIGN KEY (`discountCardNumber`) 
    REFERENCES `myschema`.`DiscountCards` (`cardNumber`) 
    ON DELETE SET NULL 
    ON UPDATE CASCADE) 
ENGINE = InnoDB; 

CREATE TABLE `myschema`.`OrderStatuses` (
    `statusID` INT NOT NULL AUTO_INCREMENT , 
    `statusTitle` VARCHAR(45) NOT NULL , 
    `statusDescription` VARCHAR(150) NULL , 
    PRIMARY KEY (`statusID`)) 
ENGINE = InnoDB; 

CREATE TABLE IF NOT EXISTS `myschema`.`WorkstationUsers` (
    `userID` INT NOT NULL AUTO_INCREMENT , 
    `login` VARCHAR(45) NOT NULL , 
    `pass` VARCHAR(45) NOT NULL , 
    `name` VARCHAR(45) NOT NULL , 
    `surname` VARCHAR(45) NOT NULL , 
    `middleName` VARCHAR(45) NULL , 
    PRIMARY KEY (`userID`)) 
ENGINE = InnoDB; 

CREATE TABLE `myschema`.`Orders` (
    `orderID` BIGINT NOT NULL AUTO_INCREMENT , 
    `registerDate` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP , 
    `clientPhone` VARCHAR(15) NOT NULL , 
    `shipmentAddress` VARCHAR(150) NOT NULL , 
    `orderStatus` INT NOT NULL , 
    `registrator` INT NOT NULL , 
    PRIMARY KEY (`orderID`) , 
    INDEX `fk_Orders_Clients` (`clientPhone` ASC) , 
    INDEX `fk_Orders_OrderStatuses1` (`orderStatus` ASC) , 
    INDEX `fk_Orders_WorkstationUsers1` (`registrator` ASC) , 
    CONSTRAINT `fk_Orders_Clients` 
    FOREIGN KEY (`clientPhone`) 
    REFERENCES `myschema`.`Clients` (`phone`) 
    ON DELETE SET NULL 
    ON UPDATE CASCADE, 
    CONSTRAINT `fk_Orders_OrderStatuses1` 
    FOREIGN KEY (`orderStatus`) 
    REFERENCES `myschema`.`OrderStatuses` (`statusID`) 
    ON DELETE SET NULL 
    ON UPDATE CASCADE, 
    CONSTRAINT `fk_Orders_WorkstationUsers1` 
    FOREIGN KEY (`registrator`) 
    REFERENCES `myschema`.`WorkstationUsers` (`userID`) 
    ON DELETE SET NULL 
    ON UPDATE CASCADE) 
ENGINE = InnoDB; 

它在失敗最後聲明（CREATE TABLE Orders）。

我已經籤：refferencing表

• 類型等於
• 指標對所有列存在
• 引擎是InnoDB

感謝您的幫助！祝你有美好的一天！

P.S.抱歉可能有重複。我在代碼中找不到任何問題。

Answer 1

某些字段被定義爲NOT NULL，但您將'ON DELETE'操作定義爲'SET NULL'。

使這些領域nullabe -

CREATE TABLE `myschema`.`Orders` (
    `orderID` BIGINT NOT NULL AUTO_INCREMENT , 
    `registerDate` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP , 
    `clientPhone` VARCHAR(15) NULL, -- NOT NULL , 
    `shipmentAddress` VARCHAR(150) NOT NULL , 
    `orderStatus` INT NULL, -- NOT NULL , 
    `registrator` INT NULL, -- NOT NULL , 
    PRIMARY KEY (`orderID`) , 
    INDEX `fk_Orders_Clients` (`clientPhone` ASC) , 
    INDEX `fk_Orders_OrderStatuses1` (`orderStatus` ASC) , 
    INDEX `fk_Orders_WorkstationUsers1` (`registrator` ASC) , 
    CONSTRAINT `fk_Orders_Clients` 
    FOREIGN KEY (`clientPhone`) 
    REFERENCES `myschema`.`Clients` (`phone`) 
    ON DELETE SET NULL 
    ON UPDATE CASCADE, 
    CONSTRAINT `fk_Orders_OrderStatuses1` 
    FOREIGN KEY (`orderStatus`) 
    REFERENCES `myschema`.`OrderStatuses` (`statusID`) 
    ON DELETE SET NULL 
    ON UPDATE CASCADE, 
    CONSTRAINT `fk_Orders_WorkstationUsers1` 
    FOREIGN KEY (`registrator`) 
    REFERENCES `myschema`.`WorkstationUsers` (`userID`) 
    ON DELETE SET NULL 
    ON UPDATE CASCADE) 
ENGINE = InnoDB;

對我來說，這個問題是通過在每個月底增加

默認字符集= UTF8

解決創建表
