mysql - 统计某个类别和月份/年份的已发布帖子数量

Question

我想统计某个类别和月份/年份的已发布帖子，但我不能...

我可以为一个类别(没有设定的月份/年份)做:

SELECT wp_term_taxonomy.count
FROM wp_terms, wp_term_taxonomy
WHERE wp_terms.term_id=wp_term_taxonomy.term_id
  AND wp_term_taxonomy.term_id=7

但不包括月份/年份:

SELECT count
FROM wp_term_taxonomy, wp_posts, wp_term_relationships
WHERE wp_posts.ID = wp_term_relationships.object_id
  AND wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id
  AND wp_term_taxonomy.term_id = '7'
  AND wp_posts.post_type = 'post'
  AND wp_posts.post_status = 'publish'
  AND wp_posts.post_date LIKE '2011-06-%'

感谢您的帮助:)

Answer 1

SELECT COUNT(*)
FROM wp_term_taxonomy, wp_posts, wp_term_relationships 
WHERE wp_posts.ID = wp_term_relationships.object_id 
AND wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id 
AND wp_term_taxonomy.term_id = '7' 
AND wp_posts.post_type = 'post' 
AND wp_posts.post_status = 'publish' 

AND YEAR(wp_posts.post_date) =2011
AND MONTH(wp_posts.post_date) =6

或者用 Between 替换最后两行

AND wp_posts.post_date BETWEEN '2011-06-01' AND '2011-06-30'
