How to exclude certains columns while using eloquent

If you only need to hide attributes from your model’s array or JSON representation, you may use one or both approaches:

• Add the
  $hidden property to your model

  class User extends Model
  {
      /**
       * The attributes that should be hidden for arrays.
       */
       protected $hidden = ['password'];
  }
  

• Use the
  makeHidden
  function

  $users = $users->makeHidden(['address', 'phone_number']);
  

See other answers for more details… But sometimes you don’t want to load huge data (geospatial, html, logs…) into your application, it will be slow and take more memory. OP asked for an SQL query hence my answer, but most of the time it’s more convenient to only hide the data from the JSON response.

AFAIK there is no build in option in SQL to exclude columns explicitly, so Laravel can’t do it. But you can try this trick

Update

Another trick is to specify all columns in your model (or use an extra query to get all columns using $this->getTableColumns() from this answer, it can also be cached after each migration to avoid two queries) then add a local scope function

// The below code requires you to define all columns in $columns.
// A better approach is to query the schema of the table and cache it after each  
// migration, for more details: https://stackoverflow.com/a/56425794/3192276

protected $columns = ['id','pseudo','email'];

public function scopeExclude($query, $value = []) 
{
    return $query->select(array_diff($this->columns, (array) $value));
}

Then you can do :

$users = User::where('gender', 'M')
    ->where('is_active', 1)
    ->exclude(['pseudo', 'email', 'age', 'created_at'])
    ->toArray();
