Insert dates in MySql Workbench

Question

I have a error when I try to insert dates with MySql Workbenck

ERROR 1452: Cannot add or update a child row: a foreign key constraint fails (myfacebook.mensajes, CONSTRAINT CodigoRedDest FOREIGN KEY (Codigo) REFERENCES redessociales (Codigo) ON DELETE NO ACTION ON UPDATE NO ACTION)

SQL statement:

INSERT INTO `myfacebook`.`mensajes` (`Codigo`, `NickUsuario`, `CodigoRedDest`, `Mensaje`, `Fecha`) 
VALUES ('7', 'MaGo', '1', 'M7', '2013-09-23')

I'm beginner and I don't know what is the problem. If you need more dates about my tables, you say me.

Thanks for your answers.

Solution

One solution is to disable the foreign key check with SET FOREIGN_KEY_CHECKS:

SET FOREIGN_KEY_CHECKS=0;
INSERT INTO `myfacebook`.`mensajes` (`Codigo`, `NickUsuario`, `CodigoRedDest`, `Mensaje`, `Fecha`) 
VALUES ('7', 'MaGo', '1', 'M7', '2013-09-23')
SET FOREIGN_KEY_CHECKS=1;
