You have an error in your SQL syntax; check the manual that corresponds to 开发者_开发技巧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.

Try:

$id= 1;
$f= $this->db->query("SELECT GROUP_CONCAT(column_name,
    \" like '%$id%' OR \" SEPARATOR '') AS str 
    FROM information_schema.columns 
    WHERE table_name='hasana_you'");
$f1= $f->row();
$filter= substr($f1->str,0,-4);

Edited:

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

It's hard to know where you want the filter... can also be:

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