You shouldn’t use a SQL query. You can do this programatically. $price = get_post_meta( $product_id, ‘_price’); $price += 100; // use -= 100 to subtract update_post_meta($product_id, ‘_price’, $price); update_post_meta($product_id, ‘_regular_price’, $price);
In my opinion and from what i’ve seen on testing. Using any WordPress function will slow things down dramatically. The fastest way i found to do this is by querying MySQL directly and grabbing only the things needed.

Can I replace the “Upgrade Network” with SQL query?
If you’re looking for raw SQL query, then this should help: UPDATE <PREFIX>postmeta SET meta_value=”temp4″ WHERE meta_value=”temp1″ AND meta_key = ‘post_template’ If you want to run this query from WP, then you can use this: global $wpdb; $wpdb->update( “{$wpdb->prefix}postmeta”, array( ‘meta_value’ => ‘temp4’ ), array( ‘meta_key’ => ‘post_template’, ‘meta_value’ => ‘temp1’ ) );
