Ben bir fk oluşturmak çalışıyorum fakat MySQL buna izin vermez ...

Identifier name 'foobarbaz_FK_CATALOG_PRODUCT_ENTITY_WEEE_DISCOUNT_PRODUCT_ENTITY' is too long [ CREATE TABLE `foobarbaz_weee_discount` (   `entity_id` int(10) unsigned NOT NULL DEFAULT '0',   `website_id` smallint(5) unsigned NOT NULL DEFAULT '0',   `customer_group_id` smallint(5) unsigned NOT NULL,   `value` decimal(12,4) NOT NULL DEFAULT '0.0000',   KEY `foobarbaz_FK_CATALOG_PRODUCT_ENTITY_WEEE_DISCOUNT_WEBSITE` (`website_id`),   KEY `foobarbaz_FK_CATALOG_PRODUCT_ENTITY_WEEE_DISCOUNT_PRODUCT_ENTITY` (`entity_id`),   KEY `foobarbaz_FK_CATALOG_PRODUCT_ENTITY_WEEE_DISCOUNT_GROUP` (`customer_group_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; ]

Is there a way to add big fks? Thank you.
