mysql-error-1005

I'm trying to create a script to normalize another table in MySQL. Below is what I have: USE hw7; SET foreign_key_checks = 0; DROP TABLE IF EXISTS airport_codes; DROP TABLE IF EXISTS airport_locations; DROP TABLE IF EXISTS airport_codenames; SET foreign_key_checks = 1; CREATE TABLE airport_codes( airport_code char(3) not null, airline_code char(2) not null, primary key (airport_code, airline_code) ); INSERT INTO airport_codes SELECT DISTINCT airport_code, airline_code FROM airport_airlines; CREATE TABLE airport_locations( airport_code char(3) not null, city varchar(20) not null, state char(2)

I've read a number of posts about this error, but none of the solutions have managed to solve the problem (assuming I've tried them correctly). This is the code that causes the error: CREATE TABLE season ( id smallint unsigned NOT NULL auto_increment, title varchar(25) NOT NULL, PRIMARY KEY (id) ); CREATE INDEX seasonId ON season(id); DROP TABLE IF EXISTS event; CREATE TABLE event ( id smallint unsigned NOT NULL auto_increment, title varchar(255) NOT NULL, season_id smallint NOT NULL, PRIMARY KEY (id), FOREIGN KEY (season_id) REFERENCES season(id) ON UPDATE RESTRICT ON DELETE RESTRICT ); So

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` ( `id` INT NOT NULL PRIMARY KEY AUTO_INCREMENT, `name` VARCHAR(255) NOT NULL, `method` TEXT NOT NULL, `image` VARCHAR(255), `user_id` INT NOT NULL, CONSTRAINT `fk_recipes_users` FOREIGN KEY(`user_id`) REFERENCES `users`(`id`) ON DELETE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8; I don't know why, but I'm getting: ERROR 1005 (HY000): Can't create table 'receitascakephp.recipes' (errno

I am trying to add foreign keys to my table but receiving this error. Error Code: 1005 Can't create table 'william.#sql-88c_3' (errno: 150) I have 3 tables. employee, client and Contract. employe [employee_no PK] , Client[customer_no PK] contract [contract_no PK] I want to have Foreign keys for contract as contract [contract_no PK, employee_no FK], customer_no FK] I tried to do directly it failed, I am now trying the alter statement.Is anything wrong with the Alter script? ALTER TABLE contract ADD CONSTRAINT `employee_no_fk2` FOREIGN KEY (`employee_no`) REFERENCES `employee` (`employee_no`);

I have this table: CREATE TABLE IF NOT EXISTS `produtos` ( `id` int(11) NOT NULL auto_increment, `idcatprodutos` int(11) NOT NULL, `idcategoria` int(11) NOT NULL, `idmarca` int(11) NOT NULL, `nome` varchar(100) NOT NULL, PRIMARY KEY (`id`), KEY `FK_produtos_2` (`idcatprodutos`), KEY `FK_produtos_3` (`idmarca`), KEY `FK_produtos_4` (`idcategoria`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 ROW_FORMAT=DYNAMIC AUTO_INCREMENT=39 ; and this table: CREATE TABLE IF NOT EXISTS `sugestoes` ( `id` int(11) NOT NULL auto_increment, `idproduto` int(11) NOT NULL, `idsugestao1` int(11) NOT NULL, `idsugestao2`

I am trying to build the database and tables for my system. But I found that if I don't add the foreign key in the codes. There is no error. I've used many method try to make the codes works, but it still have error. I am using MySQL 5.5.31, and the codes here: CREATE DATABASE TOS; DROP TABLE TOS.USER CASCADE; DROP TABLE TOS.BILL_HEADER CASCADE; DROP TABLE TOS.TOY CASCADE; CREATE TABLE TOS.USER (User Char(8), Name Char(10), Type Char(1), Password Char(12), PRIMARY KEY(User)); CREATE TABLE TOS.BILL_HEADER (Bill_No Char(10), CTime DateTime, No_Of INTEGER, Cus_No Char(5), DTime DateTime, PRIMARY
