Mathematical Formulars not functioning properly on mysql provisioning
project id 6c16bd4a-a931-4b2e-bfff-1fbbae26dad5,
my msql provisioning with the afore mentioned id, doesnt perform mathematical formulars, particularly the harversine formular, i just retruns an empty set, but everything works fine in the localhost i am developing with, it is paired with a laravel app with project ID 247ea72e-37a7-403e-80a3-26c4acbe4169

What query are you running, what error are you seeing, what are you running locally
ok let me drop a snippet of the query
$referenceLatitude = $delivery->pickup_lat;
$referenceLongitude = $delivery->pickup_long;
$referenceMedium = $delivery->medium;
$maxDistance = 10; // Maximum distance in kilometers
$earthRadius = 6371; // Earth's radius in kilometers
$driver_locations = DB::table('drivers')
->select('live_lat', 'live_long')
->selectRaw("
($earthRadius * ACOS(
COS(RADIANS($referenceLatitude)) *
COS(RADIANS(live_lat)) *
COS(RADIANS(live_long) - RADIANS($referenceLongitude)) +
SIN(RADIANS($referenceLatitude)) *
SIN(RADIANS(live_lat))
)) AS distance, id AS driver_id, name,email,phoneNumber,state,address,gender,img,medium
")
->where('availability', '=', 1)
->where('status', '=', 'active')
->where('medium', '=', $referenceMedium)
->having('distance', '<=', $maxDistance)
->orderBy('distance')
->get();
as for the error, none is returned to me, just an empty dataset, whereas locally a collection of results is being returned, it;s the exact same data both locally and on railway...
and when i try to use the query console it just says, "a cleint-side exception error has occurer", even a simple select all query fails
Are you trying to put this stuff into the Query window?
I gotta bet it's probably some escaped character stuff. For anything more than random one off queries, I'd connect to the database using some sort of client
no i just showed you the query cos u asked to see it, i didnt put it into the query console,
i connected via my mysql client and same thing still happens, but when i use my localhost conneted to phpmyadmin it works fine, and it was working earlier according to the other guy on the team who tested it too
Can you run it locally while connected to the cloud DB using the CLI?
Are you using PostGIS or something? Like, what are you running locally...
thing is i have a localhost setip using xampp, so after testing locally i push to github so it can be tested properly over the web as it's an api...on the localhost it returns an object when the query is executed, but returns null on the railway wen
Point your local app to your db on Railway and run the query. var_dump all the variables in between to narrow down what’s giving you a null
Check the MySQL version you have locally against what’s on Railway; the functions may perform differently on different versions
on local i use phpmyadmin which is fitted with mariaDb, which is a fork of mysql and is 100% compatible, infact the vey said functionality was working earleir
hello
var_dump all the variables in between to narrow down what’s giving you a nullTry this please. It was working earlier on Railway?
