我试图找出wp\\U查询的这两个参数设置之间的实际差异

      $today= date(\'Ymd\');
      $homepageEvents = new WP_Query(array(
        \'post_type\' => \'event\',
        \'posts_per_page\' => -1,
        \'orderby\' => \'meta_value_num\',
        \'meta_key\' => \'event_date\',
        \'order\' => \'ASC\',
        \'meta_query\' => array(
          array(
            \'key\' => \'event_date\',
            \'compare\' => \'>=\',
            \'value\' => $today,
            \'type\' => \'numeric\'
          )
        )
      ));

vs公司

      $today= date(\'Ymd\');
      $homepageEvents = new WP_Query(array(
        \'post_type\' => \'event\',
        \'posts_per_page\' => -1,
        \'orderby\' => \'event_date\',
        \'order\' => \'ASC\',
        \'meta_query\' => array(
          array(
            \'key\' => \'event_date\',
            \'compare\' => \'>=\',
            \'value\' => $today,
            \'type\' => \'numeric\'
          )
        )
      ));

唯一的区别在于，它被设置为orderby 使用参数meta_value_num 然后需要在字段名中添加一个元键集。另一方面orderby 只使用字段名本身。

这是否会导致相同的查询，或者我问了两个恰好有相同答案的问题？
