Trying to locate and bulk edit WooCommerce prices in MySQL

Question

I have roughly 10,000+ products in WooCommerce version 2.1.12, WordPress version 3.9.1 and through an import error, the sale price field was populated with a "0" in every product, thereby making every product now free.

So, what I need to do, of course, is a query to remove all of them, but I just can not seem to find the tables the prices are in.

I did an extensive search, I think, trying to find this in both Google and here. The closest I came was this question:

Need to get productdata out of mysql database

which looks as though it's in the meta fields, but I can not visually see them there. Anyone know the specifics of where to find the prices, and maybe a tad bit of help on the query structure?

Thanks for your time,

Answer 1

This is how you would print the prices:

SELECT p.id, p.post_title, m.meta_key, m.meta_value
FROM wp_posts p
INNER JOIN wp_postmeta m ON p.id=m.post_id 
    AND m.meta_key='_price'

What do you want to do with the prices? Update them?

To set the prices to a specific value, it is quite simple. Set price to whatever you want.

UPDATE wp_postmeta m 
    JOIN wp_posts p ON m.post_id=p.id 
    AND m.meta_key = '_price' 
    AND p.post_type = 'product'
SET m.meta_value = <price>

We released PW WooCommerce Bulk Edit to the WordPress.org repo a few days ago. This would help in your situation without needing to get into the database.

The plugin is free and would help clean up your prices. Full disclosure: there is a paid version that has more fields/features.
