如何获取两列两行的结果我的查询是-

select tt.* from wp_terms AS tt where tt.terms_id='" . $establishment['term_id'] . "' AND tt.meta_key ='phone';
select tt.* from wp_terms AS tt where tt.terms_id='" . $establishment['term_id'] . "' AND tt.meta_key ='location';

每个查询都给我结果

meta_id terms_id    meta_key    meta_value
6926     16         phone      0000 

meta_id terms_id    meta_key    meta_value
6927    16          location    xxx

现在我想要结果为

meta_id terms_id    meta_value      meta_value1
6926     16        0000          xxx

请帮忙谢谢

大概是这样的。

select phone.meta_id, phone.terms_id, phone.meta_value as phone, location.meta_value as location
from
(select tt.* from wp_terms AS tt where tt.terms_id='" . $establishment['term_id'] . "' AND tt.meta_key ='phone') phone,
(select tt.* from wp_terms AS tt where tt.terms_id='" . $establishment['term_id'] . "' AND tt.meta_key ='location') location 
where phone.meta_id = location.meta_id

【解决方案2】：

SELECT t.meta_id, t.terms_id, t.meta_value, tt.metaValue AS meta_value1
FROM wp_terms AS t
INNER JOIN wp_terms AS tt ON t.terms_id = tt.terms_id
   AND t.meta_key = 'phone'
   AND tt.meta_key = 'location'
WHERE t.terms_id='" . $establishment['term_id'] . "'
