Laravel Eloquent Query CheatSheet

SELECT your table columns in different way

You can use any type of method to select table columns for your expected result.

$user = User::query();
$user->select('`name` as another_name','age','onanno');
$user->select(['name','age','onanno',DB::raw('count(*) as user_count')]);
$user->selectRaw("`age` * ?",[2]);
$user->addSelect('column1','column2');

Writing where clause

Boost up your query writing skill with eloquent to know different type of use of where clause

$model = Model::where('age',20); // where age = 20
$model->where(age,'<',20); // where age < 20
$model->where([
    ['status' ,'=','active'],
    ['age' ,'<',20],
]);
$model->where(function($query){
    $query->where('a','=','n');
    $query->orWhere('b','=','x');
});

$model->orWhere('gender','!=','...');
$model->orWhere(function($query){
    $query->where('a','=','n');
    $query->orWhere('b','=','x');
});

$model->whereStatus('active'); // where `status` = 'active'
$model->whereColumn('updated_at','>','created_at');

$model->whereRaw("`col1` * `col2` > ?",[100]);
$model->whereRaw(DB::raw("`COL` IN (SELECT `Y1` FROM `Y` GROUP BY `Y`)"));

$model->whereExists(function($query){
    $query->select(DB::raw(1))->from('something')
    ->whereRaw('something.user_id = another.id');
});
$model->whereNotExists(function($query){
    $query->select(DB::raw(1))->from('something')
    ->whereRaw('something.user_id = another.id');
});

$model->whereBetween('age',[18,30]);
$model->whereNotBetween('age',[18,30]);

$model->whereIn('id',[1,2,3]);
$model->whereNotIn('id',[1,2,3]);

$model->whereNull('mula');
$model->whereNotNull('mula');

$model->whereIsNull('status'); // where status is null
$model->whereIsNotNull('status'); // where status is null

$model->whereDate('date_time','YYYY-MM-DD');
$model->whereYear('date_time','2018');
$model->whereMonth('date_time','12');
$model->whereDay('date_time','1');
$model->whereTime('date_time','1:00');
// Another whereHas for relational model
$model->whereHas('phone',function($q){
    $q->whereActive(1);
});
$model->whereDoesntHave('phone',function($q){
    $q->whereActive(0);
});

join your model with whatever you want

Don't be stress to join with a model to another table,model,query query builder gives us opportunity to do different types of joining.

$model = Model::query();
$model->join('table2','model.id','=','model.user_id');
$model->leftJoin('table2','model.id','=','model.user_id');
$model->join('table2',function($q){
    $q->on('model.id','=','model.user_id');
    $q->whereStatus('active')
);
$model->join(DB::raw("(SELECT * FROM omuk where tomuk IS NULL) O"),function($q){
    $q->on('O.id','=','K.name')
})

Use of Ordering, Grouping, Limit, Offset

$query = Model::query();
$query->orderBy('column1','asc')->orderBy('column2','desc');
$query->orderByRaw("(column1 - column3) asc, column2 desc");
$query->latest(); // 'created_at asc'
$query->oldest(); // 'created_at desc'
$query->inRandomOrder(); // random result

$query->groupBy('column','column2');

$query->skip(5); // skip and take both 
$query->take(2);
$query->offset(5); // offset and limit both
$query->limit(2);
