Export all subscribers who made an action



I'm trying to export all subscribers who made an action in MW (open or click) since a specific date. MW allows to export it for each campaign, but i have a lot of campaigns (300+) and it will take a lot of time to do it manually. If possible the export would contain the list which the subscriber belong and what actions he mades.

I have an access to phpmyadmin so it can be an SQL request if needed.

Thank you for your help !
@tty0 - have you tried from the filters from Customer > Lists > All Subscribers area ( /customer/index.php/lists/all-subscribers ) ?
