Question

如何将此行代码转换为MSSQL Server 2012将接受的查询？

我收到此错误在C：\ xampp \ htdocs \ pis \ application \ models \ main.php中调用boolean上的成员函数num_rows（）当我试图将其转换为查询mssql

      function login($username, $password) {



        $this -> db -> select();
        $this -> db -> from('tbl_user');
        $this -> db -> JOIN('tbl_assign_role', 'tbl_user.u_id = tbl_assign_role.tar_owner_id');
        $this -> db -> where('tbl_user.u_uname = ' . "'" . htmlspecialchars($username) . "'"); 
        $this -> db -> where('tbl_user.u_pword = ' . "'" . MD5($password) . "'"); 
        $this -> db -> where('tbl_user.is_active = 1'); 
        $this -> db -> limit(1);
        $query = $this -> db -> get();

        if($query -> num_rows() == 1)
        {
            return $query->result();
        }
        else
        {
            return false;
        }

    }

我把它改成了这个

$query = "SELECT * FROM tbl_user
                  LEFT JOIN tbl_assign_role ON tbl_user.u_id = tbl_assign_role.tar_owner_id
                  WHERE tbl_user.u_name = '".$username."'
                  AND tbl_user.u_pword = '".MD5($password)."'
                  AND tbl_user.is_active = 1
                  FETCH NEXT 1 ROWS ONLY
                  ";

我改变后，这就成了错误。

现在正在运作。我所做的是

$query = "SELECT TOP 1 * FROM tbl_user 
        JOIN tbl_assign_role ON tbl_user.u_id = tbl_assign_role.tar_owner_id 
        WHERE tbl_user.u_uname = '".htmlspecialchars($username)."' 
        AND tbl_user.u_pword = '".MD5($password)."' 
        AND tbl_user.is_active = 1";

        $query = $this->db->query($query);

希望这对你有帮助......

"SELECT tbl_user.*,tbl_assign_role.* FROM tbl_user left join tbl_assign_role on tbl_assign_role.tar_owner_id = tbl_user.u_id where tbl_user.u_uname = '".htmlspecialchars($username)."' and tbl_user.u_pword ='".MD5($password)."' and tbl_user.is_active='1' limit 1";

Codeigniter查询到mssql查询
