I forward engineered a script from a model I created in WorkBench, but the script keeps failing. It fails on the second create table:
CREATE TABLE IF NOT EXISTS `myDatabase`.`UserProfile` (
`ProfileId` INT NOT NULL AUTO_INCREMENT ,
`FirstName` VARCHAR( 45 ) NULL ,
`LastName` VARCHAR( 45 ) NULL ,
`Gender` CHAR( 1 ) NULL ,
`DOB` DATETIME NULL ,
`HairColor` VARCHAR( 20 ) NULL DEFAULT 'No Answer',
`EyeColor` VARCHAR( 20 ) NULL DEFAULT 'No Answer',
`Height` VARCHAR( 10 ) NULL DEFAULT 'No Answer',
`Weight` VARCHAR( 45 ) NULL DEFAULT 'Average',
`UserId` VARCHAR( 45 ) NOT NULL ,
PRIMARY KEY ( `ProfileId` ) ,
CONSTRAINT `FK_User_Profile` FOREIGN KEY ( `UserId` ) REFERENCES `OurAgreement`.`UserAccount` (
`UserId`
) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE = INNODB;
I believe error 150 is a foreign key issue. The table associated with this FK is create first in the script, so it exists before this constraint is attempted. Here is the DDL for that table:
CREATE TABLE IF NOT EXISTS `mydatabase`.`UserAccount` (
`UserId` INT NOT NULL AUTO_INCREMENT ,
`Login` VARCHAR(20) CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci' NOT NULL ,
`Password` CHAR(64) NOT NULL ,
`Email` VARCHAR(45) NULL ,
PRIMARY KEY (`UserId`))
ENGINE = InnoDB;
Any ideas what is going on?
EDIT============================
table with 2 FKs:
CREATE TABLE IF NOT EXISTS `MyDatabase`.`Answer` (
`AnswerId` INT NOT NULL ,
`QuestionId` INT NOT NULL ,
`ProfileId` INT NOT NULL ,
PRIMARY KEY ( `AnswerId` ) ,
INDEX `ProfileId_idx` ( `ProfileId` ASC ) ,
INDEX `QuestionId_idx` ( `QuestionId` ASC ) ,
CONSTRAINT `FK_Question_Answer` FOREIGN KEY ( `QuestionId` ) REFERENCES `MyDatabase`.`Question` (
`QuestionId`
) ON DELETE NO ACTION ON UPDATE CASCADE ,
CONSTRAINT `FK_Answer_Profile` FOREIGN KEY ( `ProfileId` ) REFERENCES `MyDatabase`.`UserProfile` (
`ProfileId`
) ON DELETE NO ACTION ON UPDATE CASCADE
) ENGINE = INNODB;
If
`UserId` INT NOT NULL AUTO_INCREMENT
is in your original table, you need exact same syntax in derived table:
`UserId` VARCHAR( 45 ) NOT NULL
should be
`UserId` INT NOT NULL
Also, you need to index the field UserId in both tables. Since it is PRIMARY in one, so no need there. In another add:
INDEX `uid`( `UserId` )
In
CREATE TABLE IF NOT EXISTS `myDatabase`.`UserProfile`
you reference table in database OurAgreement:
REFERENCES `OurAgreement`.`UserAccount`
But the table UserAccount you create earlier is in mydatabase:
CREATE TABLE IF NOT EXISTS `mydatabase`.`UserAccount`

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.
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 ,

In my case, the problem was solved by adding
DEFAULT CHARACTER SET = utf8
at the end of each create table
regards!
I ran the following query in MySQL command line and the tables were created. But when I ran in XAMPP, I got an error "1005 - Can't create table 'zoneboard.work' (errno: 150)"
My query is :
Create Table user (
id_user INT (50)NOT NULL AUTO_INCREMENT ,
email VARCHAR( 64 ) NOT NULL ,
username VARCHAR( 16 ) NOT NULL ,
password VARCHAR( 32 ) NOT NULL ,
PRIMARY KEY ( id_user )
) ENGINE = InnoDB
CREATE TABLE work (
id_user INT( 50 ) NOT NULL AUTO_INCREMENT ,
task VARCHAR( 50 ) NOT NULL ,
comments VARCHAR( 100 ) NOT NULL ,
assignee VARCHAR( 16 ) NOT NULL ,
priority VARCHAR( 50 ) NOT NULL ,
status VARCHAR( 50 ) NOT NULL ,
dataum1 VARCHAR( 50 ) NOT NULL ,
dataum2 VARCHAR( 50 ) NOT NULL ,
PRIMARY KEY ( id_user ),
FOREIGN KEY(assignee) REFERENCES user(username)
) ENGINE = InnoDB
According to MySQL Documentation : If you are creating a table, it must have the right column names and types, and it must have indexes on the referenced keys, as stated earlier. If these are not satisfied, MySQL returns error number 1005 and refers to error 150 in the error message.
Therefore, try adding an index on your foreign key field username as the following:
CREATE INDEX username_index ON 'user'(username)
You should refer to the primary key of the user table. Integer is faster and it is more secure to use the primary key instead of a none unique value. Imagine you have 2 or more rows with the same username.
CREATE TABLE `work` (
`id_user` int(50) NOT NULL AUTO_INCREMENT,
`task` varchar(50) NOT NULL,
`comments` varchar(100) NOT NULL,
`assignee` int(50) NOT NULL,
`priority` varchar(50) NOT NULL,
`status` varchar(50) NOT NULL,
`dataum1` varchar(50) NOT NULL,
`dataum2` varchar(50) NOT NULL,
PRIMARY KEY (`id_user`),
KEY `assignee` (`assignee`),
CONSTRAINT `assignee` FOREIGN KEY (`assignee`) REFERENCES `user` (`id_user`)
) ENGINE=InnoDB;
CREATE TABLE USER (
id_user INT (50)NOT NULL AUTO_INCREMENT ,
email VARCHAR( 64 ) NOT NULL ,
username VARCHAR( 16 ) NOT NULL ,
PASSWORD VARCHAR( 32 ) NOT NULL ,
PRIMARY KEY ( id_user, username ),
INDEX(username)
) ENGINE = INNODB;
Parent table-user should have an index column(Here username should be indexed).
Refer: http://dev.mysql.com/doc/refman/5.5/en/innodb-foreign-key-constraints.html
InnoDB permits a foreign key to reference any index column or group of columns. However, in the referenced table, there must be an index where the referenced columns are listed as the first columns in the same order.
I'm using MySQL to design a database, I'm exporting the code for generating the database by using the 'SQL Create Script' option on the workbench. However, when I run the code, and use SHOW TABLES I get null, which probably means no table was created in the database. This is the code that was generated (its long but since it was auto generated the error is probably from a setting I had when exporting it.)

I'm using sql command line client and putting the code but it doesn't work.
Its because you're using command line client as your database. That just makes your pc function as a database but doesn't exactly have all features a professional database would have. And MySQL workbench is designed to export code for databases more professional.
Since you're using command line client I'm assuming this is either practice or homework of some sort? Either way, this is the way the code would work in Command line client. Try this.

i got error
#1005 - Can't create table 'wew.users_companies' (errno: 121) (Details...)
can anyone tell me which one is the problem ?
You have two constraints called company.cid_FK. Rename one.
For errors like this, you can find more information with 'perror'. i.e.
shell $ perror 121
MySQL error code 121: Duplicate key on write or update
Win32 error code 121: The semaphore timeout period has expired.
I got the same error MySQL error code 121: Duplicate key on write or update.
although I deleted the table from my database to recreated again but I could not so I recreated the table yet with different constrain.
I found that the old constrain is still there.
