Prestashop Database Exception

[javiersaord]

Hi,

 

I have a flash module that calculates the measurements of the product, once calculated to give the button to add to cart see this error:

 

[PrestaShopDatabaseException]

Duplicate entry '739-6261-21011-0' for key 'PRIMARY'

UPDATE `ps_cart_product`
		SET `id_address_delivery` = (
			SELECT `id_address_delivery` FROM `ps_cart`
			WHERE `id_cart` = 739 AND `id_shop` = 1
		)
		WHERE `id_cart` = 739

The PRIMARY KEY used as an UNIQUE KEY cannot be the same as another key here your UPDATE change your id_address_delivery to 739-6261-21011-0 and seem to be already used.

[vekia]

key n ps_cart_product table contains 4 elements:

- id_cart
- id_product
- id_address_delivery
- id_product_attribute

 

in your query you update the key element (id_address_delivery)

from your sql update i see that id_address_delivery is equal to: 21011

and entry for this id cart and product already exist!
