[lmeyer1]

Questions	Answers
Description?	Add fields to the table ps_mailalert_customer_oos, in order for merchant to be able to analyze customer needs and behavior.
Type?	improvement
BC breaks?	no
Deprecations?	no
Fixed ticket?	Fixes PrestaShop/PrestaShop#30186. Prerequisite for #28233.
How to test?	Email alerts for customers should just work the same way as before.

There are these improvements in the db:

• when a customer subscribes to an alert, the time is saved to date_add
• when a notification is sent out, the time is saved to notification_sent and the line is soft-deleted.
• the notification is soft deleted on customer request or when a product is deleted
• if the customer requests deletion of his data through gdpr, the email address is anonymized.

I missed to delete all customer data. But once this is fixed, there should not remain any legal problem. Don't you think ?

@lmeyer1 can you rebase maybe on the latest version of the dev branch to avoid merge worries ?

For information, the install function has a bug preventing database creation: missing coma at the end of line 139

	`deleted` TINYINT NOT NULL DEFAULT 0,
	`notification_sent` DATETIME NULL DEFAULT NULL <===== MISSING COMA
	PRIMARY KEY  (`id_customer`,`customer_email`,`id_product`,`id_product_attribute`,`id_shop`),
`̀`

@LouisAUTHIE I hope the rebase was successful.
@souvrard Thanks for pointing this out.
