Answer 1

I resolve by problem with a SQL query :

   $queryEvent = $wpdb->get_results( 'SELECT * FROM cci_posts INNER JOIN cci_postmeta ON cci_posts.id = cci_postmeta.post_id INNER JOIN cci_term_relationships ON  cci_posts.id = cci_term_relationships.object_id WHERE cci_term_relationships.term_taxonomy_id = 4 AND cci_postmeta.meta_key = "date_de_fin" AND cci_postmeta.meta_value > 20170221 AND cci_posts.post_status = "publish" ORDER BY cci_postmeta.meta_value ASC LIMIT 3', OBJECT );
                        //$queryEvent = new WP_Query($args);
                        ?>
