Add SQL Query Executor

Is there an SQL command to add an attribute to all items in the store in bulk?

Is this a brand-new attribute that isn't currently associated with any product?

Correct

It's going to be easier to create a one-time-run PHP script. Take this template, changing 33 to the options_id and 44 to the options_values_id of the to-be-inserted attribute and saving the script in the root directory of your site (let's pretend it's add_attributes.php):

Code:

---

<?php
require 'includes/application_top.php';

$products = $db->Execute('SELECT products_id FROM ' . TABLE_PRODUCTS);
$sql_template =
    'INSERT INTO ' . TABLE_PRODUCTS_ATTRIBUTES . '
        (products_id, options_id, options_values_id)
    VALUES
        (%u, 33, 44)';
foreach ($products as $next_product) {
    $sql = sprintf($sql_template, (int)$next_product['products_id']);
    $db->Execute($sql);
}

require DIR_WS_INCLUDES . 'application_bottom.php';

---

Then on your browser's command line, enter https://mysite.com/add_attributes.php ... after you've made a database backup!

Once run, make sure that the add_attributes.php file is deleted from the site.

Oh! Interesting! Thankyou!
