You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near ‘WHERE ‘*’ = ‘0’ ) t, (SELECT @rownum:=0) r’ at line 7

SELECT @rownum:=@rownum+1 rownum, t.* FROM ( SELECT * FROM
hotel_submits ORDER BY id desc LIMIT 0, 6 WHERE * = 1 ) t, (SELECT
@rownum:=0) r

Line Number: 330

$this->db->query("SELECT @rownum:=@rownum+1 rownum, t.*
    FROM (
        SELECT *
        FROM hasana_you
        ORDER BY id desc
        LIMIT $offset, $coun_page
        WHERE * = 1 //or $id instead 1
    ) t,
    (SELECT @rownum:=0) r");

WHERE always comes before LIMIT and ORDER:

EDITED PER DISCUSSION

SELECT 
    @rownum:=@rownum+1 rownum, 
    t.*
FROM (
        SELECT 
            *
        FROM 
            hasana_you
        WHERE 
            column_a = 1 OR 
            column_b = 1 OR
            column_c = 1 OR
            column_d = 1 
        ORDER BY 
            id desc
        LIMIT 
            $offset, $count_page
) AS t

There are other issues that I see with this query (seems overly complex, may not need the subquery), but without your db structure I could not presume to correct it. However, the stated order of keywords stands as the primary concern.
