为什么我的 SQL 查询在 PHP 中不起作用？

Question

So I use ms sql to store latitude and longitude in geography point, in sql I acces that data with:

  SELECT
  location.Lat AS  lat,
  location.long AS long,
  location
  FROM tableName;

And it work good, lat is 20,4706622 long is 44,8132969 and location is some messy hexa number.

But when I try same in PHP it doesnt work, it's same and is caused by:

location.lat/long

Here is how my php looks like

<?php 
session_start();

include "connect.php";

$query = $handler->query("SELECT location.lat AS lat, street  FROM shops");
$row = $query->fetch(PDO::FETCH_OBJ);
$location[0] = $row->lat;
$location[1] = $row->street;
echo json_encode($location);

If I replace location.lat/long with anything else like location, street, city or any other column it will work. I know it is up to location.lat, but I do not know how to format it different. If anything is not clear please ask.

Answer 1

If I'm correct you named your fields location.Lat and location.long

Change your field names of your table to lat and long

Then change your query to:

SELECT
  Lat AS  lat,
  long AS long,
  location
  FROM tableName;

Another option is to create a view if you can't change the db structure for some reason.

According to you this query works:

SELECT
  location.Lat AS  lat,
  location.long AS long,
  location
  FROM tableName;

If your query works then you could create a view by:

create view new_table_name as 
SELECT location.Lat AS  lat, location.long AS long, location FROM tableName;

Then change your php script to use the new view as if it was a normal table.

Select * from new_table_name

Should give you an idea what just happened.
