Mysql SQL查询帮助

我有一个工作生成的SQL查询，但我不知道如何计算它！

GROUP BY

功能停止正常的

计数（*）

。。希望有人能帮忙

SELECT wposts.* FROM wp_posts wposts, wp_postmeta wpostmeta 
WHERE wposts.ID = wpostmeta.post_id
AND wpostmeta.meta_key = 'phone' 
AND wpostmeta.meta_value = '1542' 
AND wposts.post_status = 'publish' 
AND wposts.post_type = 'tips' || wposts.ID = wpostmeta.post_id 
AND wpostmeta.meta_key = 'phone' 
AND wpostmeta.meta_value = '1541' 
AND wposts.post_status = 'publish' 
AND wposts.post_type = 'tips' || ........ 
GROUP BY wposts.post_content 
ORDER BY wposts.post_title ASC
