How to Create Multiple Where Clause Query Using Laravel Eloquent?

问题


I\'m using the Laravel Eloquent query builder and I have a query where I want a WHERE clause on multiple conditions. It works, but it\'s not elegant.

Example:

$results = User::where(\'this\', \'=\', 1)
    ->where(\'that\', \'=\', 1)
    ->where(\'this_too\', \'=\', 1)
    ->where(\'that_too\', \'=\', 1)
    ->where(\'this_as_well\', \'=\', 1)
    ->where(\'that_as_well\', \'=\', 1)
    ->where(\'this_one_too\', \'=\', 1)
    ->where(\'that_one_too\', \'=\', 1)
    ->where(\'this_one_as_well\', \'=\', 1)
    ->where(\'that_one_as_well\', \'=\', 1)
    ->get();

Is there a better way to do this, or should I stick with this method?


回答1:


In Laravel 5.3 you can use more granular wheres passed as array:

$query->where([
    ['column_1', '=', 'value_1'],
    ['column_2', '<>', 'value_2'],
    [COLUMN, OPERATOR, VALUE],
    ...
])

Personally I haven't found use-case for this over just multiple where calls, but fact is you can use it.

Since June 2014 you can pass an array to where

As long as you want all the wheres use and operator, you can group them this way:

$matchThese = ['field' => 'value', 'another_field' => 'another_value', ...];

// if you need another group of wheres as an alternative:
$orThose = ['yet_another_field' => 'yet_another_value', ...];

Then:

$results = User::where($matchThese)->get();

// with another group
$results = User::where($matchThese)
    ->orWhere($orThose)
    ->get();

The above will result in such query:

SELECT * FROM users
  WHERE (field = value AND another_field = another_value AND ...)
  OR (yet_another_field = yet_another_value AND ...)

Query scopes may help you to let your code more readable.

http://laravel.com/docs/eloquent#query-scopes

Updating this answer with some example:

In your model, create scopes methods like this:

public function scopeActive($query)
{
    return $query->where('active', '=', 1);
}

public function scopeThat($query)
{
    return $query->where('that', '=', 1);
}

Then, you can call this scopes while building your query:

$users = User::active()->that()->get();

You can use subqueries in anonymous function like this:

 $results = User::where('this', '=', 1)
            ->where('that', '=', 1)
            ->where(function($query) {
                /** @var $query Illuminate\Database\Query\Builder  */
                return $query->where('this_too', 'LIKE', '%fake%')
                    ->orWhere('that_too', '=', 1);
            })
            ->get();



回答4:


In this case you could use something like this:

User::where('this', '=', 1)
    ->whereNotNull('created_at')
    ->whereNotNull('updated_at')
    ->where(function($query){
        return $query
        ->whereNull('alias')
        ->orWhere('alias', '=', 'admin');
    });

It should supply you with a query like:

SELECT * FROM `user` 
WHERE `user`.`this` = 1 
    AND `user`.`created_at` IS NOT NULL 
    AND `user`.`updated_at` IS NOT NULL 
    AND (`alias` IS NULL OR `alias` = 'admin')

Conditions using Array:

$users = User::where([
       'column1' => value1,
       'column2' => value2,
       'column3' => value3
])->get();

Will produce query like bellow:

SELECT * FROM TABLE WHERE column1=value1 and column2=value2 and column3=value3

Conditions using Antonymous Function:

$users = User::where('column1', '=', value1)
               ->where(function($query) use ($variable1,$variable2){
                    $query->where('column2','=',$variable1)
                   ->orWhere('column3','=',$variable2);
               })
              ->where(function($query2) use ($variable1,$variable2){
                    $query2->where('column4','=',$variable1)
                   ->where('column5','=',$variable2);
              })->get();

Will produce query like bellow:

SELECT * FROM TABLE WHERE column1=value1 and (column2=value2 or column3=value3) and (column4=value4 and column5=value5)

Multiple where clauses

    $query=DB::table('users')
        ->whereRaw("users.id BETWEEN 1003 AND 1004")
        ->whereNotIn('users.id', [1005,1006,1007])
        ->whereIn('users.id',  [1008,1009,1010]);
    $query->where(function($query2) use ($value)
    {
        $query2->where('user_type', 2)
            ->orWhere('value', $value);
    });

   if ($user == 'admin'){
        $query->where('users.user_name', $user);
    }

finally getting the result

    $result = $query->get();



回答7:


The whereColumn method can be passed an array of multiple conditions. These conditions will be joined using the and operator.

Example:

$users = DB::table('users')
            ->whereColumn([
                ['first_name', '=', 'last_name'],
                ['updated_at', '>', 'created_at']
            ])->get();

$users = User::whereColumn([
                ['first_name', '=', 'last_name'],
                ['updated_at', '>', 'created_at']
            ])->get();

For more information check this section of the documentation https://laravel.com/docs/5.4/queries#where-clauses




回答8:


Model::where('column_1','=','value_1')->where('column_2 ','=','value_2')->get();

OR

// If you are looking for equal value then no need to add =
Model::where('column_1','value_1')->where('column_2','value_2')->get();

OR

Model::where(['column_1' => 'value_1','column_2' => 'value_2'])->get();

Be sure to apply any other filters to sub queries, otherwise the or might gather all records.

$query = Activity::whereNotNull('id');
$count = 0;
foreach ($this->Reporter()->get() as $service) {
        $condition = ($count == 0) ? "where" : "orWhere";
        $query->$condition(function ($query) use ($service) {
            $query->where('branch_id', '=', $service->branch_id)
                  ->where('activity_type_id', '=', $service->activity_type_id)
                  ->whereBetween('activity_date_time', [$this->start_date, $this->end_date]);
        });
    $count++;
}
return $query->get();

$projects = DB::table('projects')->where([['title','like','%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])
->orwhere([['owner', 'like', '%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])->get();



回答11:


You can use eloquent in Laravel 5.3

All results

UserModel::where('id_user', $id_user)
                ->where('estado', 1)
                ->get();

Partial results

UserModel::where('id_user', $id_user)
                    ->where('estado', 1)
                    ->pluck('id_rol');



回答12:


Without a real example, it is difficult to make a recommendation. However, I've never needed to use that many WHERE clauses in a query and it may indicate a problem with the structure of your data.

It may be helpful for you to learn about data normalization: http://en.wikipedia.org/wiki/Third_normal_form




回答13:


use whereIn condition and pass the array

$array = [1008,1009,1010];

User::whereIn('users.id', $array)->get();




回答14:


You can use array in where clause as shown in below.

$result=DB::table('users')->where(array(
'column1' => value1,
'column2' => value2,
'column3' => value3))
->get();



回答15:


DB::table('users')
            ->where('name', '=', 'John')
            ->orWhere(function ($query) {
                $query->where('votes', '>', 100)
                      ->where('title', '<>', 'Admin');
            })
            ->get();



回答16:


As per my suggestion if you are doing filter or searching

then you should go with :

        $results = User::query();
        $results->when($request->that, function ($q) use ($request) {
            $q->where('that', $request->that);
        });
        $results->when($request->this, function ($q) use ($request) {
            $q->where('this', $request->that);
        });
        $results->when($request->this_too, function ($q) use ($request) {
            $q->where('this_too', $request->that);
        });
        $results->get();



回答17:


Use This

$users = DB::table('users')
                    ->where('votes', '>', 100)
                    ->orWhere('name', 'John')
                    ->get();



回答18:


Using pure Eloquent, implement it like so. This code returns all logged in users whose accounts are active. $users = \App\User::where('status', 'active')->where('logged_in', true)->get();




回答19:


public function search()
{
    if (isset($_GET) && !empty($_GET))
    {
        $prepareQuery = '';
        foreach ($_GET as $key => $data)
        {
            if ($data)
            {
                $prepareQuery.=$key . ' = "' . $data . '" OR ';
            }
        }
        $query = substr($prepareQuery, 0, -3);
        if ($query)
            $model = Businesses::whereRaw($query)->get();
        else
            $model = Businesses::get();

        return view('pages.search', compact('model', 'model'));
    }
}

$variable = array('this' => 1,
                    'that' => 1
                    'that' => 1,
                    'this_too' => 1,
                    'that_too' => 1,
                    'this_as_well' => 1,
                    'that_as_well' => 1,
                    'this_one_too' => 1,
                    'that_one_too' => 1,
                    'this_one_as_well' => 1,
                    'that_one_as_well' => 1);

foreach ($variable as $key => $value) {
    User::where($key, '=', $value);
}
