My query is as below

  

     $querydetails = "
       SELECT wposts.*
       FROM $wpdb->posts wposts 
       INNER JOIN $wpdb->postmeta wpostmeta ON wposts.ID = wpostmeta.post_id 
       INNER JOIN $wpdb->term_relationships yprelation ON yprelation.object_id = wposts.ID
       INNER JOIN $wpdb->term_taxonomy wptaxonomy ON wptaxonomy.term_taxonomy_id = yprelation.term_taxonomy_id
       INNER JOIN $wpdb->terms wpterms ON wpterms.term_id = wptaxonomy.term_id
       WHERE wpostmeta.meta_key = 'event_date'
       AND STR_TO_DATE(wpostmeta.meta_value, '%d-%m-%Y %H:%i:%s') >= NOW()
       AND (wposts.post_status = 'publish' || wposts.post_status = 'pending' || wposts.post_status = 'future')
       AND wposts.post_type = 'events'
       AND (wpterms.term_id = 5 OR wptaxonomy.parent = 5)
       ORDER BY STR_TO_DATE(wpostmeta.meta_value, '%d-%m-%Y %H:%i') LIMIT 0,10";

I want to convert this query into wp_query, I have tried below code

        $args = array(
        'post_type' => 'events',
        'post_status' => array('publish', 'pending', 'future'),
        'orderby' => 'meta_value',
        'order' => 'ASC',
        'meta_query' => array(
            'relation' => 'AND',
            array(
                'key' => 'event_date',
                'value' => date('Y-m-d H:i:s'),
                'type' => 'date',
                'compare' => '>='
            )
        ),
        'tax_query' => array(
            'relation' => 'and',
            array(
                'taxonomy' => 'ad_cat',
                'field' => 'slug',
                'terms' => 'event-2'
            )
        )
    );
    
    $query = new WP_Query($args);
    echo "Last SQL-Query: {$query->request}";

retuns below result
    
    SELECT SQL_CALC_FOUND_ROWS yp_posts.ID 
    FROM yp_posts 
    INNER JOIN yp_term_relationships ON (yp_posts.ID = yp_term_relationships.object_id) 
    INNER JOIN yp_postmeta ON (yp_posts.ID = yp_postmeta.post_id) 
    WHERE 1=1 
    AND ( yp_term_relationships.term_taxonomy_id IN (581,541,547,544,545,546,548,550,572,585,599,607,616,619) ) 
    AND yp_posts.post_type = 'events' 
    AND ((yp_posts.post_status = 'publish' OR yp_posts.post_status = 'future' OR yp_posts.post_status = 'pending')) 
    AND ( (yp_postmeta.meta_key = 'event_date' 
    	AND CAST(yp_postmeta.meta_value AS DATE) >= '2014-12-24 04:30:01') ) 
    GROUP BY yp_posts.ID ORDER BY yp_posts.post_date ASC LIMIT 0, 10 

but did not get expected results

only issue is it return
`AND CAST(yp_postmeta.meta_value AS DATE) >= '2014-12-24 04:30:01') ) `  
instead of  
`AND STR_TO_DATE(wpostmeta.meta_value, '%d-%m-%Y %H:%i:%s') >= NOW()`

please help
