MySQL 日期比较过滤器

我有一些运行良好的 SQL 代码，并从我的 Wordpress 数据库返回所需的结果。

但是，我根本无法理解如何过滤以下日期之间的日期：

2010-12-10 00:00:00

and

2010-12-15 00:00:00

这是我的 SQL 代码：

$SQL_K =  "SELECT SQL_CALC_FOUND_ROWS wp_posts.* 
             FROM wp_posts 
             JOIN wp_postmeta ON (wp_posts.ID = wp_postmeta.post_id)
            WHERE 1 = 1 
              AND wp_posts.post_type = 'post' 
              AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private') 
              AND wp_postmeta.meta_key = 'expiry_date' 
         GROUP BY wp_posts.ID 
         ORDER BY wp_posts.post_date DESC 
            LIMIT 0, 100 ";

WHERE date_column BETWEEN STR_TO_DATE('2010-12-10', '%Y-%m-%d') AND STR_TO_DATE('2010-12-15', '%Y-%m-%d')

Like so?

编辑：忘记了结束语。哎呀

EDITv2：使用更新的查询添加代码

EDITv3：很少优化删除了 1=1 比较，对 wp_posts.post_status 使用 IN()

SELECT      SQL_CALC_FOUND_ROWS wp_posts.* 
FROM        wp_posts 
  JOIN      wp_postmeta 
  ON        (wp_posts.ID = wp_postmeta.post_id) 
WHERE       wp_posts.post_type = 'post' 
  AND       (wp_posts.post_status IN ('publish','private'))
  AND       wp_postmeta.meta_key = 'expiry_date' 
  AND       ___INSERT_NAME_OF_DATE_COLUMN_HERE___
    BETWEEN STR_TO_DATE('2010-12-05', '%Y-%m-%d')
      AND   STR_TO_DATE('2010-12-15', '%Y-%m-%d')
GROUP BY    wp_posts.ID 
ORDER BY    wp_posts.post_date DESC 
LIMIT       0, 100
