title: Wordpress Woocommerce change all products to out of stock
body: <p>Hello i have a online shop using Wordpress and Woocommerce but i have the following problem. I need to change all of my 2000 products to be out of stock, i haven't selected any quantity i only need to change the status. I started doing it by hand but it will take quite a while to mark all the items. After browsing the net i saw that this can be done relatively easy in phpmyadmin, the status is stored in wp_postmeta, i myself tried fiddling with the queries of phpmyadmin but to no avail  . Can someone help me with building the query that i need to use ? I use WP 4.1.1</p>
