How can the ORDER BY clause in a SQL query impact the sorting of WordPress articles based on custom fields?

When sorting WordPress articles based on custom fields in a SQL query, the ORDER BY clause can be used to specify the custom field to sort by. This can impact the sorting of articles by arranging them in ascending or descending order based on the custom field values. To implement this, you can modify the SQL query in your WordPress template file to include the ORDER BY clause with the custom field name. 

$args = array(
    'post_type' => 'post',
    'meta_key' => 'custom_field_name',
    'orderby' => 'meta_value_num',
    'order' => 'DESC',
);

$query = new WP_Query( $args );

if ( $query->have_posts() ) {
    while ( $query->have_posts() ) {
        $query->the_post();
        // Output your post content here
    }
} else {
    // No posts found
}

wp_reset_postdata();
