Question

I am working few days with my project and I stuck on phpmyadmin sql.
I create in workbench ERR Diagram which looks like:

And the code to paste into sql query is:

    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';

Adres means Address
Ogloszenie means Advertistment
Wojewodztwa means Province
Material means Material
Szczegoly means Details

This simple project is about advertistment which sells houses.
My error is

Executing SQL script in server

ERROR: Error 1005: Can't create table 'nieruchomosci.adres' (errno: 150)

I am total yellow in sql, where did I make mistake?

Answer 1

I think you reference the foreign key at the wrong position.
Instead of having the following in the definition of adres

CONSTRAINT `fk_adres_ogloszenie1`
FOREIGN KEY (`id_adres` )
REFERENCES `nieruchomosci`.`ogloszenie` (`id_adres` )
ON DELETE NO ACTION
ON UPDATE NO ACTION)

You should put this in the definition of the ogloszenie table.

Hope that helps.
