I'm creating a database of greatest Movies, and i'm getting error:
ERROR 1005 (HY000) at line 19: Can't create table 'Greatest_Movies.genre' (errno: 150)
I have checked this Post:
Error Code: 1005. Can't create table '...' (errno: 150) and tried lot of things but with no succes.
This is what actually have:
DROP DATABASE `Greatest_Movies`;
CREATE DATABASE `Greatest_Movies`;
USE `Greatest_Movies` ;
CREATE TABLE IF NOT EXISTS `movie` (
`id` INT UNSIGNED NOT NULL AUTO_INCREMENT,
`film` VARCHAR(255) NOT NULL,
`director` VARCHAR(255) NOT NULL,
`release_year` VARCHAR(255) NOT NULL,
`oscars` TINYINT NULL,
`IMDB_link` VARCHAR(255) NOT NULL,
`film_page` VARCHAR(255) NOT NULL,
`country` VARCHAR(255) NOT NULL,
`genre` TINYINT UNSIGNED NOT NULL,
PRIMARY KEY (`id`) )
ENGINE = InnoDB;
CREATE TABLE IF NOT EXISTS `genre` (
`id` TINYINT UNSIGNED NOT NULL AUTO_INCREMENT,
`name` VARCHAR(255) NOT NULL,
PRIMARY KEY (`id`),
FOREIGN KEY (`id`) REFERENCES `movie`(`genre`))
ENGINE = InnoDB;
What i'm missing?

This script work and tested, try it:
DROP DATABASE `Greatest_Movies`;
CREATE DATABASE `Greatest_Movies`;
USE `Greatest_Movies` ;
DROP TABLE IF EXISTS `genre`;
CREATE TABLE `genre` (
`id` tinyint(3) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
DROP TABLE IF EXISTS `movie`;
CREATE TABLE `movie` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`film` varchar(255) NOT NULL,
`director` varchar(255) NOT NULL,
`release_year` varchar(255) NOT NULL,
`oscars` tinyint(4) DEFAULT NULL,
`IMDB_link` varchar(255) NOT NULL,
`film_page` varchar(255) NOT NULL,
`country` varchar(255) NOT NULL,
`genre` tinyint(3) unsigned NOT NULL,
PRIMARY KEY (`id`),

CONSTRAINT `genre_fk` FOREIGN KEY (`genre`) REFERENCES `genre` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
I think you need to remove the comma from the end of this line:
`genre` TINYINT UNSIGNED NOT NULL,
And also after:
`name` VARCHAR(255) NOT NULL,
As #Solarflare said on the comments, I did this changes:
DROP DATABASE `Greatest_Movies`;
CREATE DATABASE `Greatest_Movies`;
USE `Greatest_Movies`;
CREATE TABLE IF NOT EXISTS `genre` (
`id` TINYINT UNSIGNED NOT NULL AUTO_INCREMENT,
`name` VARCHAR(255) NOT NULL,
PRIMARY KEY (`id`))
ENGINE = InnoDB;
CREATE TABLE IF NOT EXISTS `movie` (
`id` INT UNSIGNED NOT NULL AUTO_INCREMENT,
`film` VARCHAR(255) NOT NULL,
`director` VARCHAR(255) NOT NULL,
`release_year` VARCHAR(255) NOT NULL,
`oscars` TINYINT NULL,
`IMDB_link` VARCHAR(255) NOT NULL,
`film_page` VARCHAR(255) NOT NULL,
`country` VARCHAR(255) NOT NULL,
`genre` TINYINT UNSIGNED NOT NULL,
PRIMARY KEY (`id`),
FOREIGN KEY (`genre`) REFERENCES `genre`(`id`))
ENGINE = InnoDB;

I am trying to create database table and get them connected by mysql FOREIGN KEYS. I have ensured that my data types are identical. I also ensure that my tables are made before added the FK. Any advice would be greatly appreciated.
CREATE TABLE IF NOT EXISTS `af_feeds` (
`id` int(64) unsigned NOT NULL AUTO_INCREMENT,
`hash` char(255) NOT NULL,

I get
errnno 150: InnoDB Documentation

Here is the SQL:
-- Table structure for table `Serving_Info`
--
CREATE TABLE IF NOT EXISTS `Serving_Info` (
`id` int(255) NOT NULL AUTO_INCREMENT,
`Food_Value` varchar(40) NOT NULL,
`Food_name` varchar(40) NOT NULL,
`Served_On` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
`Oncall` varchar(128) NOT NULL,
Foreign key(`Oncall`) REFERENCES `employees`(`name`),
Foreign key(`Food_name`) REFERENCES `Foods`(`Food_name`),
PRIMARY KEY (`Oncall`,`Food_name`, `Served_On`)
);
Any idea what is causing the error? I have tried making id part of the primary key but that isn't solving the problem either.
Here are the statements for the tables I am referencing:
CREATE TABLE IF NOT EXISTS `employees` (
`id_user` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(128) NOT NULL,
`email` varchar(64) NOT NULL,
`phone_number` varchar(16) NOT NULL,
`username` varchar(16) NOT NULL,
`password` varchar(32) NOT NULL,
`confirmcode` varchar(32) DEFAULT NULL,
PRIMARY KEY (`id_user`)
);
--
-- Table structure for table `Foods`
--
CREATE TABLE IF NOT EXISTS `Foods` (
`Food_name` varchar(40) NOT NULL,
`CostPerRefill` double NOT NULL,
PRIMARY KEY (`Food_name`)
);
I just tried the below but I get the same error:
--
-- Table structure for table `Serving_Info`
--
CREATE TABLE IF NOT EXISTS `Serving_Info` (
`id` int(255) NOT NULL AUTO_INCREMENT,
`Food_Value` varchar(40) NOT NULL,
`Food_name` varchar(40) NOT NULL,
`Served_On` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
`Oncall` varchar(128),
Foreign key(`Oncall`) REFERENCES `employees`(`name`),
Foreign key(`Food_name`) REFERENCES `Foods`(`Food_name`),
PRIMARY KEY (`id`),
UNIQUE (`Oncall`,`Food_name`, `Served_On`)
);
Your problem is that the reference is to employees.name rather than employees.id_user. Try this:
CREATE TABLE IF NOT EXISTS `Serving_Info` (
`id` int(255) NOT NULL AUTO_INCREMENT,
`Food_Value` varchar(40) NOT NULL,
`Food_name` varchar(40) NOT NULL,
`Served_On` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
`Oncall` int,
PRIMARY KEY (`id`),
Foreign key(`Oncall`) REFERENCES `employees`(`id_user`),
Foreign key(`Food_name`) REFERENCES `Foods`(`Food_name`),
UNIQUE (`Oncall`,`Food_name`, `Served_On`)
);
Otherwise, change the employees table so name has an index:
CREATE TABLE IF NOT EXISTS `employees` (
`id_user` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(128) NOT NULL ,
`email` varchar(64) NOT NULL,
`phone_number` varchar(16) NOT NULL,
`username` varchar(16) NOT NULL,
`password` varchar(32) NOT NULL,
`confirmcode` varchar(32) DEFAULT NULL,
PRIMARY KEY (`id_user`),
KEY (name)
);
In practice, if you are going to use name this way, you should probably make that unique rather than just key.
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?

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?
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
I have tried everything in solving this issue and yes I know that this type of question is already asked here but I could not solve my issue
It is mysql database

Can't create table '.\project\comments.frm' (errno: 150)
the foreign keys are matching in structure (i.e length and type) then what can be the possible problem in the table creation
Table which is giving error is comments:
CREATE TABLE `comments`(
`id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
`description` VARCHAR(100) NOT NULL,
`user_id` INT(10) UNSIGNED NOT NULL,

FOREIGN KEY (`post_id`) REFERENCES `posts`.`id`,
FOREIGN KEY (`user_id`) REFERENCES `users`.`id`,
PRIMARY KEY (`id`)
) ENGINE=INNODB DEFAULT CHARSET=latin1;`
Here is posts table which is already created in the databas
CREATE TABLE `posts` (
`id` int(10) unsigned NOT NULL auto_increment,
`title` varchar(30) default NULL,
`description` longtext,
`image` varchar(50) default NULL,

Here is the users table which is also already created in the database

Your syntax is incorrect. The REFERENCES keyword should be followed by table (columns):
CREATE TABLE `comments`(
`id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
`description` VARCHAR(100) NOT NULL,
`user_id` INT(10) UNSIGNED NOT NULL,
`post_id` INT(10) UNSIGNED NOT NULL,
FOREIGN KEY (`post_id`) REFERENCES `posts` (`id`),
FOREIGN KEY (`user_id`) REFERENCES `users` (`id`),
PRIMARY KEY (`id`)
) ENGINE=INNODB DEFAULT CHARSET=latin1;
CREATE TABLE `users` (
`id` INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
`name` VARCHAR(255) NOT NULL,
`username` VARCHAR(75) NOT NULL,
`password` VARCHAR(75) NOT NULL,
`image` VARCHAR(255)
);
CREATE TABLE `recipes` (

I don't know why, but I'm getting:

Both tables need to be InnoDB:
