ERROR 1452: Cannot add or update a child row: a foreign key constraint fails

Question

I have created tables in MySQL Workbench as shown below :

ORDRE table:

CREATE TABLE Ordre (
  OrdreID   INT NOT NULL,
  OrdreDato DA         


        

Answer 1

Its 100% working...

ERROR 1452: Cannot add or update a child row: a foreign key constraint fails.... if this type of error occur : then First of all goto this table and check in setting > if Engine is: InnoDB then change its to MyISAM

(and delete references foreign constraint)
