2个相同的查询数据库返回不同的结果

Question

I'm using Yii2 ActiveRecord & ActiveQuery to retrieve data from database, but I'm facing different results:

    $ne_lat = 53.42712825923;
    $sw_lat = 53.39008549731;
    $ne_lon = -2.1651649475098;
    $sw_lon = -2.288761138916;

    $poi = Point::find()

        ->andWhere('latitude <= :ne_lat', [':ne_lat' => $ne_lat])
        ->andWhere('latitude >= :sw_lat', [':sw_lat' => $sw_lat])
        ->andWhere('longitude <= :ne_lon', [':ne_lon' => $ne_lon])
        ->andWhere('longitude >= :sw_lon', [':sw_lon' => $sw_lon])
        ->andWhere(['status' => 1])
        ->asArray()
        ->all();

returns 0 an empty array. But same query get just by a little bit different way:

   $poi = Point::findBySql('SELECT * 
      FROM `point` 
      WHERE (((((latitude <= 53.42712825923) 
      AND (latitude >= 53.39008549731)) 
      AND (longitude <= -2.1651649475098)) 
      AND (longitude >= -2.288761138916)) 
      AND (`status`=1))
   ')->asArray()->all();

returns 30+ results. Results look like this:

id,          name,         latitude,         longitude
1 ,        point1,       53.3917409,        -2.1684337    
2 ,        point2,       53.4135577,        -2.1673014    
3 ,        point3,       53.3991094,        -2.2513453    

It looks like there is something wrong with binding floats because

  $sql = "
        SELECT *
        FROM point
        WHERE latitude <= :ne_lat
          AND latitude >= :sw_lat
          AND longitude <= :ne_lon
          AND longitude >= :sw_lon
          AND status=1
    ";

    $poi = Fitter::findBySql($sql, [':ne_lat' => $ne_lat, ':sw_lat' => $sw_lat, ':ne_lon' => $ne_lon, ':sw_lon' => $sw_lon])->asArray()->all();

Also doesn't return any record

Does anybody know why?

Answer 1

$sw_lon = 2.288761138916; <-- this is positive in the first query while in the second it is negative (-2.288761138916).

Answer 2

if I'm not wrong, using the find() method will return you this query statement.

SELECT * FROM point WHERE (atitude <= 53.42712825923) AND (latitude >= 53.39008549731) AND (longitude <= -2.1651649475098) AND (longitude >= -2.288761138916) AND ( status =1)

And not

SELECT * FROM point WHERE (((((latitude <= 53.42712825923) AND (latitude >= 53.39008549731)) AND (longitude <= -2.1651649475098)) AND (longitude >= -2.288761138916)) AND ( status =1))

The difference in sql statement might be the cause.

Answer 3

您可以在第一个查询构建器中尝试用“状态= 1”代替“状态” => 1吗？
