mysql - Wordpress中的meta键和meta_value查询

我正在wordpress中成功运行一个查询。查询如下。

SELECT wp_posts.*, wp_postmeta.meta_value FROM wp_posts, wp_postmeta, wp_term_relationships, wp_terms
WHERE term_id = '12' AND term_taxonomy_id = '12' AND ID = post_id
AND ID = object_id AND post_type = 'property' AND post_status = 'publish'
AND meta_key = 'property_amount' AND replace( replace(meta_value, ',', ''), '"', '' ) >= 1
GROUP BY wp_posts.ID ORDER BY replace( replace(meta_value, ',', ''), '"', '' ) DESC
LIMIT 0, 10

但我想在上面的查询中再添加一个meta_键及其值条件，所以我将查询改为

  SELECT wp_posts.*, wp_postmeta.meta_value FROM wp_posts, wp_postmeta, wp_term_relationships, wp_terms
  WHERE term_id = '12' AND term_taxonomy_id = '12' AND ID = post_id
  AND ID = object_id AND post_type = 'property' AND post_status = 'publish'
  AND meta_key = 'property_amount' AND replace( replace(meta_value, ',', ''), '"', '' )
>= 1
  AND meta_key="property_land_type" and meta_value IN ('L','H','C')
  GROUP BY wp_posts.ID ORDER BY replace( replace(meta_value, ',', ''), '"', '' ) DESC
  LIMIT 0, 10

以下行在第一个查询中是多余的

meta_key="property_land_type" and meta_value in ('L','H','C')

但它不起作用。怎么做？我这次不能写WP_查询，因为我有很多其他基于这个查询的查询。
提前谢谢！!!

最佳答案

一列中有多个meta_键，对于meta_键和值

meta_key IN( 'property_amount','property_land_type')
AND meta_value IN ('L','H','C',replace( replace(meta_value, ',', ''), '"', '' ) >= 1)

尝试此查询

SELECT wp_posts.*, wp_postmeta.meta_value FROM
wp_posts, wp_postmeta, wp_term_relationships, wp_terms
WHERE term_id = '12' AND term_taxonomy_id = '12' AND ID = post_id
AND ID = object_id AND post_type = 'property' AND post_status = 'publish'
AND meta_key IN( 'property_amount','property_land_type')
AND meta_value IN ('L','H','C',replace( replace(meta_value, ',', ''), '"', '' ) >= 1)
GROUP BY wp_posts.ID ORDER BY replace( replace(meta_value, ',', ''), '"', '' ) DESC
LIMIT 0, 10

编辑
用join试试这个，我已经为两个meta_键加入了wp_postreta两次

SELECT wp.*, wpm1.meta_value AS `propert_type`,
wpm2.meta_value AS `property_amount`
FROM
wp_posts  wp
LEFT JOIN wp_postmeta wpm1 ON (wp.ID = wpm1.post_id)
LEFT JOIN wp_postmeta wpm2 ON (wp.ID = wpm2.post_id)
INNER JOIN wp_term_relationships wptr ON (wp.ID = wptr.object_id)
INNER JOIN `wp_term_taxonomy` wptt ON (wptr.term_taxonomy_id = wptt.term_taxonomy_id)
INNER JOIN wp_terms wpt ON (wptt.term_id = wpt.term_id)

WHERE wpt.term_id = '12' AND wptr.term_taxonomy_id = '12'
AND  wp.post_type = 'property' AND wp.post_status = 'publish'
AND wpm1.meta_key = 'property_land_type'
AND wpm2.meta_key = 'property_amount'
AND REPLACE( REPLACE(wpm2.meta_value, ',', ''), '"', '' ) >= 1
AND wpm1.meta_value IN ('L','H','C') AND  wpm1.meta_value IS NOT NULL AND  wpm2.meta_value IS NOT NULL
GROUP BY wp.ID ORDER BY REPLACE( REPLACE(wpm2.meta_value, ',', ''), '"', '' ) DESC
LIMIT 0, 10
