Question

I want to query posts in WordPress by ID range. For example query posts that have ID between 9 – 40. Or get posts that have IDs greater than 9 (ID>9).
How can I specified this type of query in WordPress?
Thanks a lot.

Try this filter, just paste this function in your functions.php

function filter_by_id($where = '')
{
    $where .= " AND ID > 50 AND ID < 100";
    return $where;
}

And in your template file

add_filter( 'posts_where', 'filter_by_id');
$args=array(...);
$my_post = new WP_Query($args);
while ( $my_post->have_posts() ) : $my_post->the_post();
    // your code
endwhile;
remove_filter('posts_where' , 'filter_by_id');
