Question

I’m modeling my database with MySQL Wordbench in a EER Model, which is this :

So after modeling my database I export to a SQL script and try to run it, but it creates only three tables:

Why is that happening ?
It shouldn’t create all tables ?

This is the generated script when I export:

    SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0;
SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;
SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='TRADITIONAL';

CREATE SCHEMA IF NOT EXISTS `brainset` DEFAULT CHARACTER SET latin1 COLLATE latin1_general_ci ;
USE `brainset` ;

Just in case anyone stumbles upon this; you can’t create a table with a relation to a table that’s not created yet.

When MySQL creates a relation it links the table you’re creating the relation for to the table you’re referencing, if the referencing table doesn’t exist, MySQL won’t be happy about it.

So when creating a lot of tables that reference each other, make sure that any table that is referenced by another is created before the table that references it.
