# How to Get SKU Number from WooCommerce Database
Finding the SKU (Stock Keeping Unit) number for a product within your WooCommerce database might seem daunting, but with the right approach, it’s straightforward. This article guides you through several methods, explaining how to retrieve SKU data effectively and safely. Understanding where this data resides and how to access it responsibly is crucial for maintaining your store’s integrity.
Understanding WooCommerce Database Structure and SKU Location
Before diving into the methods, it’s essential to understand the database structure. WooCommerce stores product information, including SKUs, primarily within the `wp_posts` and `wp_postmeta` tables. The `wp_posts` table holds general post information, while `wp_postmeta` stores the meta data, including the SKU. The `post_type` column in `wp_posts` will identify your product posts (`product`). The SKU itself is stored as meta_value in `wp_postmeta`, linked to the product via post_id. Improperly querying these tables can lead to data corruption, so proceed with caution.
Methods to Retrieve SKU Numbers
There are several ways to access your WooCommerce SKUs from the database. Let’s examine the most common and reliable methods.
Method 1: Using phpMyAdmin (or similar MySQL client)
This is a direct approach using a database management tool like phpMyAdmin. It’s powerful but requires caution. Always back up your database before making any changes or running queries.
Here’s a sample SQL query to retrieve all SKUs:
SELECT pm.meta_value AS sku FROM wp_posts p JOIN wp_postmeta Check out this post: How To Integrate My Woocommerce With Facebook pm ON p.ID = pm.post_id WHERE p.post_type = 'product' AND pm.meta_key = '_sku';
This query joins the `wp_posts` and `wp_postmeta` tables, filtering for product posts (`post_type = ‘product’`) and specifically retrieving the `meta_value` where the `meta_key` is `_sku`. You can adjust this query to filter for specific products by adding `WHERE` clauses (e.g., `WHERE p.post_title LIKE ‘%Your Product%’`).
Method 2: Using a Custom WordPress Plugin (Recommended)
This is the safest and most recommended method. Creating a simple plugin allows you to execute the database query within the WordPress environment, reducing the risk of accidental data damage. Here’s a basic example:
<?php /**
- Plugin Name: WooCommerce SKU Retriever
function get_woocommerce_skus() {
global $wpdb;
$skus = $wpdb->get_col( $wpdb->prepare( “
SELECT pm.meta_value
FROM {$wpdb->posts} p
JOIN {$wpdb->postmeta} pm ON p.ID = pm.post_id
WHERE p.post_type = ‘product’
AND pm.meta_key = ‘_sku’

return $skus;
}
$all_skus = get_woocommerce_skus();
foreach ($all_skus as $sku){
echo $sku . “
“;
}
?>
This code snippet retrieves all SKUs and displays them. Remember to place this code in a file (e.g., `woocommerce-sku-retriever.php`) and activate it in your WordPress plugin directory. This method uses the WordPress database object (`$wpdb`) which is a more secure and efficient way to interact with your database.
