Question

我已在下面添加了查询。我要按两件事订购这些帖子，一个日期和一个美元金额。

除一个小错误外，这两种排序机制似乎都在起作用。十亿美元的美元数量出现在数百万美元的数量下降之后。

$args = array(
    'post_type' => 'trecord',
    'post_status' => 'publish',
    'posts_per_page' => -1,
    'tax_query' => array(
        array(
            'taxonomy' => 'businesssector',
            'terms' => $post_slug,
            'field' => 'slug',
        )
    ),
    'meta_query' => array(
        'relation' => 'AND',
        'tombstone_year' => array(
            'key'     => 'mandate',
            'type' => 'NUMERIC',
            'compare' => 'EXISTS'
        ),
        'tombstone_size' => array(
            'key'     => 'size',
            'compare' => 'EXISTS',
            'type' => 'NUMERIC'
        ),

    ),
    'orderby' => array(
        'tombstone_year' => 'DESC',
        'tombstone_size' => 'DESC',
    ),

);

这是SQL转储。因此，我可以看到美元金额已按签名转换，因此应该可以进行排序。

SELECT wp_posts.* FROM wp_posts LEFT JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id ) INNER JOIN wp_postmeta AS mt1 ON ( wp_posts.ID = mt1.post_id ) WHERE 1=1 AND ( wp_term_relationships.term_taxonomy_id IN (28) ) AND ( wp_postmeta.meta_key = 'mandate' AND mt1.meta_key = 'size' ) AND wp_posts.post_type = 'trecord' AND ((wp_posts.post_status = 'publish')) GROUP BY wp_posts.ID ORDER BY CAST(wp_postmeta.meta_value AS SIGNED) DESC, CAST(mt1.meta_value AS SIGNED) DESC

为什么以下查询不适用于数字数据类型？
