How do I use on delete cascade in mysql?

I have a database of components. Each component is of a specific type. That means there is a many-to-one relationship between a component and a type. When I delete a type, I would like to delete all the components which has a foreign key of that type. But if I'm not mistaken, cascade delete will delete the type when the component is deleted. Is there any way to do what I described?

From stackoverflow

• Here's what you'd include in your components table.

  CREATE TABLE `components` (
      `id` int(10) unsigned NOT NULL auto_increment,
      `typeId` int(10) unsigned NOT NULL,
      `moreInfo` VARCHAR(32), 
      -- etc
      PRIMARY KEY (`id`),
      KEY `type` (`typeId`)
      CONSTRAINT `myForeignKey` FOREIGN KEY (`typeId`)
        REFERENCES `types` (`id`) ON DELETE CASCADE ON UPDATE CASCADE
  )
  

  Just remember that you need to use the InnoDB storage engine: the default MyISAM storage engine doesn't support foreign keys.
