我正在尝试根据lat和lng获取最近的位置,但我想添加有距离<查询中的子句。
但我可以在哪里使用。??
select p.id, p.name, p_i.image as image,
( 3959 * acos( cos( radians(26.916279) ) *
cos( radians( lat ) ) *
cos( radians( lng ) - radians(75.8082) ) +
sin( radians(26.916279) ) *
sin( radians( lat ) ) ) ) AS distance
from `places` as p
inner join `place_images` as p_i
on p.`id` = p_i.`place_id`
where p.`city_id` = '1'
and p.status = 'active'
and p_i.display_order = '1'
limit 0, 5
当前结果
答案 0 :(得分:2)
尝试此查询
where p.`city_id` = '1' and p.status = 'active'
and p_i.display_order = '1'
HAVING distance < 5
limit 0, 5
最后使用limit
答案 1 :(得分:2)
您最后可以在having
limit
子句
select p.id, p.name, p_i.image as image, ( 3959 * acos( cos( radians(26.916279) )
* cos( radians( lat ) ) * cos( radians( lng ) - radians(75.8082) )
+ sin( radians(26.916279) ) * sin( radians( lat ) ) ) ) AS distance
from `places` as p inner join `place_images` as p_i on p.`id` = p_i.`place_id`
where p.`city_id` = '1' and p.status = 'active' and p_i.display_order = '1'
HAVING distance < 5 limit 0, 5

HAVING distance < 5 # add this
limit 0, 5
