像这么的查询还有别的什么方法可写吗

public function find()
    {
        $sql = "SELECT * FROM qsj_user_profile
        RIGHT JOIN qsj_user ON qsj_user.uid = qsj_user_profile.uid";
        if(!empty($_GET['email']))
        {
            $sql.="AND qsj_user.email=".$_GET['email'];
        }
        if(!empty($_GET['nickname']))
        {
            $sql.="AND qsj_user_profile.nickname = ".$_GET['nickname'];
        }
        if(!empty($_GET['province']))
        {
            $sql.="AND qsj_user_profile.province =".$_GET['province'];
        }
        if(!empty($_GET['city']))
        {
            $sql.="AND qsj_user_profile.city =".$_GET['city'];
        }
        if(!empty($_GET['dist']))
        {
            $sql.="AND qsj_user_profile.dist = ".$_GET['dist'];
        }
        if(!empty($_GET['style']))
        {
            $sql.="AND qsj_user_profile.style =".$_GET['style'];
        }
        $query = $this->db->query($sql);
        return $query->result_array();
        
    }
