title: Remove all skus from woocommerce database
body: <p>We have asked this question before with out success, hope someone can help this time.</p>
  
  <p>We have a site with over 1200 sku's that are wrong and we want to delete them all without affecting the products.</p>
  
  <p>We are running the latest version of WP.</p>
  
  <p>Is there a quicker way to do this via the db in phpmyadmin.</p>
  
  <p>Any help would be great.</p>
  
  <p>Thanks</p>
