Show lowest simple product price in category page

I want to display the lowest simple product price in the content-oroduct_cat.php page. The following code from Fancy Squares works for showing the lowest price but I want to show Simple products only, i.e. omit grouped products.

/* SHOW LOWEST PRICE ON CATEGORY PAGE */
//woocommerce get lowest price in category
function wpq_get_min_price_per_product_cat($term_id)
{    
    global $wpdb;

    $sql = "
    SELECT  MIN( meta_value+0 ) as minprice
    FROM {$wpdb->posts} 
    INNER JOIN {$wpdb->term_relationships} ON ({$wpdb->posts}.ID = {$wpdb->term_relationships}.object_id)
    INNER JOIN {$wpdb->postmeta} ON ({$wpdb->posts}.ID = {$wpdb->postmeta}.post_id) 
    WHERE  
      ( {$wpdb->term_relationships}.term_taxonomy_id IN (%d) ) 
    AND {$wpdb->posts}.post_type = 'product'  
    AND {$wpdb->posts}.post_status = 'publish' 
    AND {$wpdb->postmeta}.meta_key = '_price'
    ";

    return $wpdb->get_var($wpdb->prepare($sql, $term_id));
}

I tried using :

AND {$wpdb->posts}.product_type = 'simple'

but this didn't work. How would I display only simple products?

You query is not working because product_type is not stored in posts table it is stored in term_taxonomy table. To get the desired you have to use Sub query, which will fetch all the simple product and the main query filter it according to category.

I have modified your wpq_get_min_price_per_product_cat() as below

function wh_get_min_price_per_product_cat($term_id)
{
    global $wpdb;

    $sql = "
    SELECT  MIN( meta_value+0 ) as minprice
    FROM {$wpdb->posts} 
    INNER JOIN {$wpdb->term_relationships} ON ({$wpdb->posts}.ID = {$wpdb->term_relationships}.object_id)
    INNER JOIN {$wpdb->postmeta} ON ({$wpdb->posts}.ID = {$wpdb->postmeta}.post_id) 
    WHERE  
      ( {$wpdb->term_relationships}.term_taxonomy_id IN (%d) ) 
        AND {$wpdb->posts}.post_type = 'product' 
        AND {$wpdb->posts}.post_status = 'publish' 
        AND {$wpdb->postmeta}.meta_key = '_price'
        AND {$wpdb->posts}.ID IN (SELECT posts.ID
                FROM {$wpdb->posts} AS posts
                INNER JOIN {$wpdb->term_relationships} AS term_relationships ON posts.ID = term_relationships.object_id
                INNER JOIN {$wpdb->term_taxonomy} AS term_taxonomy ON term_relationships.term_taxonomy_id = term_taxonomy.term_taxonomy_id
                INNER JOIN {$wpdb->terms} AS terms ON term_taxonomy.term_id = terms.term_id
                WHERE term_taxonomy.taxonomy = 'product_type'
                AND terms.slug = 'simple'
                AND posts.post_type = 'product')";
    return $wpdb->get_var($wpdb->prepare($sql, $term_id));
}

Code goes in functions.php file of your active child theme (or theme). Or also in any plugin php files.

USAGE 

echo wh_get_min_price_per_product_cat($cat_id);

Code is tested and works.

Hope this helps!
