I am using Query Builder and here is my code in Laravel5
$users = DB::table('brand_customers')
->select('brand_id')
->where('mobile', $mobile)
->take(15)
->get();
I am limiting to 15 records but I am also looking for total count. Currently, I am getting count using this.
$users->count();
I tried the above code but no luck. How can I get both the data and count with the same query. Thanks.
Use two separate statements like:
$users = DB::table('brand_customers')
->select('brand_id')
->where('mobile', $mobile);
$count = $users->count();
$users = $users->take(15)->get();

I want to use count and sum together on DB Query not sure how to go about it. I've tried several combinations but keep getting an error. I know I can just use a raw query but would like to learn how to use it correctly
Working:
DB::select('SELECT count(*) AS order_count, sum(total_including_vat)
AS orders_total FROM orders WHERE user_id =' .$userProfile->id);
Not Working
DB::table('orders')->where('user_id', '=', $userProfile->id)->count()->Sum();
count same as aggregates returns single value so
// you try to call method sum on number and it fails
DB::table('orders')->where('user_id', $userProfile->id)->count()->sum();
you can make two requests to get sum and count but its not a good idea, or get data in collection and let it do the math
// not a good idea
//$count = DB::table('orders')->where('user_id', $userProfile->id)->count();
//$sum = DB::table('orders')->where('user_id', $userProfile->id)->sum('total_including_vat');
//collection way
$orders = DB::table('orders')
->where('user_id',$userPorfile->id)
->get(['id', 'total_including_vat']);
$result = [
'order_count' => $orders->count(),
'orders_total' => $orders->sum('total_including_vat')
];
or the same result as for your working example with mix raw expressions
$result = DB::table('orders')
->where('user_id', $userProfile->id)
->selectRaw('count(1) as order_count, sum(total_including_vat) as orders_total')
->first();
How can I get the total number of records for each of the grouped column(some_id) results generated in this eloquent query? (Answers generated using DB query builder or vanilla PHP also welcome).
$results = \App\MyModel::groupBy('some_id')
->whereNotNull('some_id')
// some query here to get sum of each grouped column records
->get();
The desired result would be such that when I'm looping through the results, I can also have a field called for example totalRecords for each grouped results. i.e.
foreach($results as $result) {
echo $result->totalRecords;
}
$results = DB::table('your_table')
->select('some_column_name', DB::raw('count(some_id) as totalRecords'))
->whereRaw('some_id IS NOT NULL')
->groupBy('some_id')
->get();
You can do like this :-
$results = \App\MyModel::select('*', DB::raw('count(some_id) as totalRecords'))
->groupBy('some_id')
->whereNotNull('some_id')
->get();
foreach ($results as $result) {
echo $result->totalRecords;
}
Collection Provide itself count() method.
But sometime once you fetch whole collection using get(). You can use count method on collection something like this:
$results = \App\MyModel::groupBy('some_id')
->whereNotNull('some_id')
// some query here to get sum of each grouped column records
->get();
dd($results->count());
Also, If your data is not collection then Php array's provide you count method you can use that too:
dd(count($results));
I used dd method just for debuging purpose.That will show you result before actual output.
count() method of array will help you to count collection as well as sub collection or array of sub array.
Good luck !!!
I have an array of $ids.
I'd like to essentially say:
foreach($ids as $id):
$user = User::find(1);
$user->life_expectancy -= 1;
$user->save();
endforeach;
Except I have thousands of ids in the array, and I'd much rather do something like:
$users = User::whereIn('id', $ids)->update(array('life_expectancy' => --1));
To just get it done in a single query. But that isn't going to work... is there another method?
I know I can update multiple users to all have the same life_expectancy, but I'd like it to be a modification of the previous value.
Check out this site, http://community.sitepoint.com/t/one-sql-statement-to-subtract-and-update-a-field-value/4673 if you decide to use a raw query, but looking on laravel's docs I think you can just do this,
$users = DB::table('users')
->whereIn('id', $ids)->decrement('life_expectancy');
App\User::whereIn('id',[1,2])->decrement('life_expectancy');
If you need -2 use next string:
App\User::whereIn('id',[1,2])->decrement('life_expectancy',2);
I'm new to Laravel and i need your help please.
This runs on my controller and the result should be "3" as long as I have 3 rows with that title in the same table.
$countcategories = DB::table('categories')
->select(DB::raw('count(title) as result'))
->where('title','=','dsds')
->get();
I'm passing the query result to the view like this->with('counts', $countcategories)
And now my questions are:
In the view I can only display the result by using foreach. Why? My query returns only one row.
I want to store the query result in a variable inside my controller in order to use that result. How can I do that?
Thank you very much!
you should use ->first() method:
$countcategories = DB::table('categories')
->select(DB::raw('count(title) as result'))
->where('title','=','dsds')
->first();
What you are getting are rows from a result, it tunrs out there is only one in your situation.
You have already done that.
Anyways, here's my approach:
// The result
$categories = Category::where('title','=','dsds');
foreach( $categories->all() as $category ) {
echo $category->title . "\n";
}
// The count
echo $categories->count();
I am using Eloquent ORM outside of Laravel-4 and I am building a custom Paginator.
First, I build a query using Fluent Query Builder. I want to get the number of result the query could return using count() and then I do a custom pagination using take(x) and skip(y). I need to do the count() before the take()->skip()->get() so I dont fall outside of the page range. The problem is that when I use the count() method on the query, it seems to remove any select I added previously.
I isolated the problem to this simple example:
$query = DB::table('companies')
->join('countries','companies.country_id','=','countries.id')
->select(
'companies.name as company_name',
'countries.name as country_name'
);
$nbPages = $query->count();
$results = $query->get();
//$results contains all fields of both tables 'companies' and 'countries'
If i invert the order of the count and get, it works fine:
$results = $query->get();
$nbPages = $query->count();
//$results contains only 'company_name' and 'country_name'
Question: is there a more elegant way the using something like this:
$tmp = clone $query;
$nbPages = $tmp->count();
$results = $query->get();
There is not, unfortunately. Open issue on github about the problem: https://github.com/laravel/framework/pull/3416
