WHERE p.post_type in('product', 'product_variation') AND p.post_status = 'publish' AND
p.post_content <> ''

If you want to get a list of products with parent_category and sub_category in an array format, then you can use WordPress WP_Query. Try following code snippet.
<?php
// fetch all products from woocommerce
$args = array('post_type' => 'product', 'posts_per_page' => -1);
$loop = new WP_Query($args);
$product_list_array = []; // result array with product_id,parent_category and sub_category
while ($loop->have_posts()) : $loop->the_post();
global $product;
$product_id = $product->get_id();
$result = []; $parent_cats = []; $sub_cats = [];
$result['product_id'] = $product_id;
$categories = get_the_terms($product_id, 'product_cat'); // get category list of a product
foreach ($categories as $category) {
// check if it is a parent or child
if ($category->parent == 0) {
$parent_cats[] = $category->name;
} else {
$parent_cat = get_term_by('id', $category->parent, 'product_cat'); // to get parent category name
$sub_cats[] = $category->name;
$parent_cats[] = $parent_cat->name;
}
}
// if multiple category exist then join them to a string
$result['parent_category'] = implode(" | ", array_unique($parent_cats));
$result['sub_category'] = implode(" | ", array_unique($sub_cats));
$product_list_array[] = $result;
endwhile;
?>
The $product_list_array should contain product_id,parent_category and sub_category.
