Can you add setWhere function ?

[hunteryun]

sorry, my English is poor, and I'm not sure if I knew enough before I asked.

I have a need like this ：

` $v = explode(',', $filter['value']);

$where = $query->where()->subWhere("OR");

foreach ($v as $item) {

$where->equals($op_field, $item);

}

$query = $query->setWhere($where);

` so if have a setWhere function , it will very easy :

in NilPortugues\Sql\QueryBuilder\Manipulation\AbstractBaseQuery file add this ：

` /** * @return $this */ public function setWhere(Where $where) { $this->where = $where;

    return $this;
}

`

Thanks for your great project.
