MySQL table creation - mysql

Question

Below is the code I used in MySQL workbench to create the database as well as the tables. Finally I have mentioned the error I face. Could anyone please help me with this?
delimiter $$
CREATE DATABASE `sa38team4` /*!40100 DEFAULT CHARACTER SET utf8 */$$
Employee Table :
delimiter $$
CREATE TABLE `employee` (
`EmpID` int(11) NOT NULL AUTO_INCREMENT,
`EmpName` varchar(100) NOT NULL,
`DOB` datetime NOT NULL,
`Gender` varchar(10) NOT NULL,
`Password` varchar(50) NOT NULL,
`ContactNumber` varchar(45) NOT NULL,
`Email` varchar(45) DEFAULT NULL,
`Role` varchar(15) NOT NULL,
`Address` varchar(200) DEFAULT NULL,
PRIMARY KEY (`EmpID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8$$
Inventory Table :
delimiter $$
CREATE TABLE `inventory` (
`ItemID` int(11) NOT NULL AUTO_INCREMENT,
`PID` int(11) NOT NULL,
`TotalQty` int(11) NOT NULL,
`Availability` int(11) NOT NULL,
`ReorderPt` int(11) NOT NULL,
`MinOrdQty` int(11) NOT NULL,
`UnitPrice` decimal(10,2) NOT NULL,
PRIMARY KEY (`ItemID`),
KEY `PID` (`PID`),
CONSTRAINT `PID` FOREIGN KEY (`PID`) REFERENCES `productdetail` (`PID`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=utf8$$
`MID` varchar(45) NOT NULL,
`Manufacturer` varchar(100) NOT NULL,
`Model` varchar(45) NOT NULL,
`PartNo` varchar(45) NOT NULL,
`ItemDesc` varchar(100) NOT NULL,
PRIMARY KEY (`PID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8$$
Product Details Table :
delimiter $$
CREATE TABLE `productdetail` (
`PID` int(11) NOT NULL AUTO_INCREMENT,
`MID` varchar(45) NOT NULL,
`Manufacturer` varchar(100) NOT NULL,
`Model` varchar(45) NOT NULL,
`PartNo` varchar(45) NOT NULL,
`ItemDesc` varchar(100) NOT NULL,
PRIMARY KEY (`PID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8$$
Trans In Table :
delimiter $$
CREATE TABLE `transin` (
`TransID` int(11) NOT NULL AUTO_INCREMENT,
`Date` datetime NOT NULL,
`EmpID` int(11) NOT NULL,
`ItemID` int(11) NOT NULL,
`Qty` int(11) NOT NULL,
`UnitPrice` decimal(10,2) NOT NULL,
`Remark` varchar(100) DEFAULT NULL,
PRIMARY KEY (`TransID`),
KEY `EmpID` (`EmpID`),
KEY `ItemID` (`ItemID`),
CONSTRAINT `EmpID` FOREIGN KEY (`EmpID`) REFERENCES `employee` (`EmpID`) ON DELETE NO ACTION ON UPDATE NO ACTION,
CONSTRAINT `ItemID` FOREIGN KEY (`ItemID`) REFERENCES `inventory` (`ItemID`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=utf8$$
All the four above tables are created.
TransOut Tablle :
delimiter $$
CREATE TABLE `transout` (
`TransID` int(11) NOT NULL AUTO_INCREMENT,
`Date` datetime NOT NULL,
`EmpID` int(11) NOT NULL,
`ItemID` int(11) NOT NULL,
`Qty` int(11) NOT NULL,
`UnitPrice` decimal(10,2) NOT NULL,
`Remark` varchar(100) DEFAULT NULL,
PRIMARY KEY (`TransID`),
KEY `EmpID` (`EmpID`),
KEY `ItemID` (`ItemID`),
CONSTRAINT `EmpID` FOREIGN KEY (`EmpID`) REFERENCES `employee` (`EmpID`) ON DELETE NO ACTION ON UPDATE NO ACTION,
CONSTRAINT `ItemID` FOREIGN KEY (`ItemID`) REFERENCES `inventory` (`ItemID`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=utf8$$
The last table n creation, shows an error as
"Error Code : 1005. Can't create table 'sa38team4.transout'(errno: 121)"
Could anyone please help me?

Answer 1

Check out this post : MySQL errorno 121
As said :
Check that all your constraints are really spelled out correctly, also check that there's not any other tables that uses the constraint names ItemID or EmpID
So I think that you may use another name into your TransOut table for ItemID & EmpID
