This is my problem

If I write this sql query


UPDATE `grupos` SET `id_grupo` = '5' WHERE `id_grupo` = 3

SQL answer:

#1451 - Cannot delete or update a parent row: a foreign key constraint fails (`dbs780743`.`grupos`, CONSTRAINT `grupos_ibfk_1` FOREIGN KEY (`prueba`) REFERENCES `grupos` (`id_grupo`) ON DELETE SET NULL ON UPDATE CASCADE)
