Mysql Forward engineer errno 150 - mysql

Question

I'm modeling my db shema using MySQL Workbench CE EER modeler and now I'm stuck with mysql errno 150.
My sql code:
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;
It fails in last statement (CREATE TABLE Orders).
I already checked:
Types of refferencing tables are equals
Indexes on all columns exists
Engine is InnoDB
Thanks for any help! Have a good day!
P.S. sorry for possible duplicate. I really can't find any problem in my code.

Answer 1

Some of fields are defined as NOT NULL, but you defined 'ON DELETE' action as 'SET NULL'.
Make these fields 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;

In my case, the problem was solved by adding
DEFAULT CHARACTER SET = utf8
at the end of each create table
