I have the following query:
public static function artists_most_popular() {
$artists_most_popular = DB::table('artists')
->join('fanartists', 'artists.id', '=', 'fanartists.artist_id')
->orderBy(DB::raw('count(*)', 'DESC'))
->groupBy('artists.id')
->take(50)
->get();
return $artists_most_popular;
}
As you can see from the query, I would like the data to appear in descending order by count of the times the artist_id appears in the fanartists table. However, when I use "foreach" and output this data, it appears in ascending order. Any ideas for why this is happening? I used the following query in SQL Pro, and it works as it should:
select *, COUNT(*)
from artists
join fanartists on artists.id = fanartists.artist_id
group by artists.id
order by (COUNT(*)) desc
I have changed the query little bit. Hopefully this will work.
$artists_most_popular = DB::table('artists')
->join('fanartists', 'artists.id', '=', 'fanartists.artist_id')
->select(DB::raw('artists.*, fanartists.*, COUNT(*) AS total_artists'))
->orderBy('total_artists', 'DESC'))
->groupBy('artists.id')
->take(50)
->get();
Also if you want your Artists collection to be returned (this pretends your Artists Model is called Artists), and to further enhance Anam's response, you could do something like:
$artists_most_popular = Artists::join('fanartists', 'artists.id', '=', 'fanartists.artist_id')
->select(DB::raw('artists.*, fanartists.*, COUNT(*) AS total_artists'))
->orderBy('total_artists', 'DESC'))
->groupBy('artists.id')
->take(50)
->get();

i want to ask about sql in postgresql, i got data from join with 3 table, i got the result but i got multiple data like this image
result
and here my sql code in postgresql
select users.* from users inner join model_has_roles on model_has_roles.model_id = users.id
left join roles on roles.id = model_has_roles.role_id where roles.name not in ('job-seeker') order by users.name asc
how to fix this query where i got the multiple data only 1 data to show.
and i want this sql to implement to laravel query and here my code now
public function getAccountList(){
$req = app(Request::class);
// $getAccount = User::query();
$getAccount = User::join('model_has_roles', function($join) {
$join->on('users.id', '=', 'model_has_roles.model_id');
})->leftJoin('roles', function($join){
$join->on('model_has_roles.role_id', '=', 'roles.id');
});
$getAccount->whereNotIn('roles.name', ['job-seeker']);
if ($q = $req->query('q')) {
$searchTerm = trim(strtolower($q));
$getAccount->whereRaw(
'LOWER(users.name) like (?) or LOWER(users.email) like (?)',
["%{$searchTerm}%", "%{$searchTerm}%"]
);
}
// $getAccount->get()->unique('name');
$getAccount->select(['users.*']);
$paginator = $this->pagination($getAccount);
return $this->paginate($paginator, new UserTransformer);
}
how to fix the query only 1 data to show not the multiple same data. thank you for helping me. God Bless You
use distinct()
$data = DB::table('test')->[your query builder]->distinct()->get();

Just change a bit to make it related to your query builder
I have a scores table that I have to group by the attempt_number and take the sum of scores
I want to nest this query using Eloquent and SQL raw and take the Max score from the attempts and order it according to score. I need the final result as a leaderboard.
$usersByScore = Attempt::where('game_id',$id)
->select('user_id','attempt_no','game_id',DB::raw('SUM(score) as total_score'))
->groupBy('attempt_no')
->orderBy('total_score', 'DESC')
->get()
this gives me the leaderboard but it has all attempts from the user. I need just the max score attempt for each user ordered by the score in descending order.
use distinct() method for this: i hope it will work.
$usersByScore = Attempt::where('game_id',$id)
->select('user_id','attempt_no','game_id',DB::raw('SUM(score) as total_score'))
->groupBy('attempt_no')
->orderBy('total_score', 'DESC')
->distict()
->get()
Got the solution - Implemented the from method to nest the query
$usersByScore = Attempt::with('user')
->select(DB::raw('MAX(tscore) as total_score, user_id,attempt_no'))
->from(DB::raw('(SELECT user_id,attempt_no,SUM(score) as tscore FROM
attempts WHERE game_id = '.$id.' GROUP By attempt_no,user_id) AS T'))
->groupBy('user_id')
->get();
I'm sure I have done something like this before, but can't find it and google not being helpful.
Using Phalcon model if possible, I want to select the items from a table whose ID appears the most - i.e. 10 most popular items ordered by popularity. Is this possible using Model::find("conditions")? I do I have to use PHQL for this?
using model::find
Model::find([
'columns' => 'id,count(id) as counter',
'group' => 'id',
'order' => 'counter DESC'
]);
PHQL:
$this->modelsManager->executeQuery('SELECT count(id) AS counter,id FROM ModelName GROUP BY id ORDER BY counter DESC');
find() does have a group clause, but I don't think it's possible to do what you want because you also need to do a count.
Talal's answer is close, but won't work if you want a list of model objects.
Something like this should work:
$Results = $this->modelsManager->executeQuery('SELECT * FROM ModelName GROUP BY id ORDER BY count(id) DESC LIMIT 10');
$Results->setHydrationMode(\Phalcon\Mvc\Model\Resultset::HYDRATE_RECORDS);
Setting the hydration mode may not be necessary, as Phalcon may default to that mode based on the fact the query is asking for *.
How to get a result with groupBy(month('start_date'))
So far I have
$this->data['earnings'] = DB::table('documents')
->leftJoin('users','users.id', '=', 'documents.users_id')
->leftJoin('users_editors','users_editors.user_id','=','users_id')
->groupBy(month ('start_date'), 'DESC')
->sum('amount')
->get();
I am trying to get earnings for all the editors groupBy month which will take month from start_date to have a groupBy on.
Thanks
In order to use (My)SQL functions you need raw statements, that are not processed and bound by PDO or, in this case, treated as a field name:
->groupBy(DB::raw('month(start_date)'))
In order to make it work as you expect:
->selectRaw('month(start_date) as month, sum(amount) as sum')
->groupBy(DB::raw('month desc'))
// or:
->groupBy('month')
->orderBy('month', 'desc')
->get();
I have orm query like tthis:
$userCountries = ORM::factory('User')
->select(array(DB::expr('countries.code, COUNT("countries.id") as total')))
->join('countries')
->on('user.country_id', '=', 'countries.id')
->group_by('country.name')
->order_by('total', 'DESC')
->find_all();
What i want is country code with total users quantity from country.
I do not know what is wrong here. I spent 3 hours on it with no success.
What is wrong with this query?
Your SELECT Params is wrong
->select('countries.code', array(DB::expr('COUNT("countries.id")', 'total')))
I think the Group by should be
->group_by('countries.name') instead of ->group_by('country.name')
So Your Total Query will look like
$userCountries = ORM::factory('User')
->select('countries.code', array(DB::expr('COUNT("countries.id")', 'total')))
->join('countries')
->on('user.country_id', '=', 'countries.id')
->group_by('countries.name')
->order_by('total', 'DESC')
->find_all();`
