php - 我如何在 Laravel 中使用 BETWEEN 和 AND

Question

您好，我正在尝试使用以下内容，但不确定如何解决此问题

SELECT * FROM search_users  
WHERE 
  match(first_name,last_name,country,city,location,nationality,short_bio) 
  against (?)   
AND 
  search_users.loc_lng BETWEEN '-0.24272918701172' AND '-0.24272918701172' 
AND 
  search_users.loc_lat BETWEEN '51.47026338272' AND '51.47026338272'

我正在尝试编写一个与

完全相同的 laravel 查询

select * from search_users  
where 
  ......   
  and search_users.loc_lng BETWEEN '-0.24272918701172' AND '-0.24272918701172' 
  AND search_users.loc_lat BETWEEN '51.47026338272' AND '51.47026338272'

如果您只想构建查询/获取纯数据而无需任何逻辑，您可以简单地使用查询构建器:

$results = DB::table('search_users')
           ->where('first_name', $firstname)
           ->where('last_name', $last_name)
           ->where('country', $country) //and so on
           ->whereBetween('loc_lng', array(-0.24272918701172, -0.24272918701172))
           ->whereBetween('loc_lat', array(51.47026338272, 51.47026338272))
           ->get();

果然，如果您正在使用模型，您可以使用相同的语法:

$users = User::where('key1', $value1)
             ->where('key2', $value2)
             ->whereBetween('loc_lng', array(-0.24272918701172, -0.24272918701172))
             ->whereBetween('loc_lat', array(51.47026338272, 51.47026338272))
             ->get();

关于如何在 eloquent 中使用 AND 的问题的一些额外解释:

如果您使用 2 个或更多 where()，则默认使用

AND。所以

DB::table('search_users')->where('first_name', $firstname)
                         ->where('last_name', $last_name)

等于

SELECT * FROM search_users  WHERE first_name = ? AND last_name = ?

对于OR，你可以使用orWhere():

DB::table('search_users')->where('first_name', $firstname)
                         ->orWhere('last_name', $othername)

等于

SELECT * FROM search_users  WHERE first_name = ? OR first_name = ?

有时您可能需要更复杂的东西，例如:

SELECT * FROM search_users  
WHERE first_name = ? 
  AND (last_name = ? OR last_name = ?)
  AND age > 27

在 Eloquent 中，这将是:

DB::table('search_users')
      ->where('first_name', $firstname)
      ->where(function($query) {
          $query->where('last_name', $lastName1);
          $query->orWhere('last_name', $lastName2);
      })
      ->where('age', '>', 27)
