Using Wp-query with serialized postmeta values

Using Wp-query with serialized postmeta values

I've stored some serialized data in wp-postmeta table, e.g.:
$data = array (
'details' => $dettagli,
'vernice' => $vernice,
'reperibile' => $reperibile,
'valore2' => $valore2,
'valuta2' => $valuta2,
'subcat' => $subcat
);
add_post_meta($post_ID, 'meta', $data);
I would like to extract all the posts with the key "details" and value =
"4". How can I do it?
I've tried doing this code:
$args = array(
'post_type' => 'custom-post-type',
'posts_per_page' => -1,
'meta_query' =>
array(
'key' => 'details',
'value' => '4',
'compare' => 'LIKE'
),
'meta_key' => 'meta',
);
$query = new WP_Query( $args );
if($query->have_posts()){
while($query->have_posts()){
$query->the_post();
the_ID();
}
}
What is wrong?
