จะทำยังไงให้ join ตาราง ตามข้อมูลที่ส่งไปครับ รบกวนช่วยดูด้วยครับ

$sql="select table1.*,table2.*,table3.* form table1,table2,table3 where table1.field1=table2.field2";
$qr=mysql_query($sql);

$sql = 'SELECT m.id_m As id , m.name_m As name , m.idcard_m As idcard , m.address_m As address , m.rdate_m As rdate , '
        . ' v.id_village As village , v.village As vill , '
        . ' s.id_status As status , s.status As sta , '
        . ' w.id_welfare As welfare , w.welfare As wel '
        . ' FROM member m INNER JOIN village v ON m.id_village = v.id_village '
        . ' INNER JOIN status s ON m.id_status = s.id_status '
        . ' INNER JOIN welfare w ON m.id_welfare = w.id_welfare WHERE m.id = '.$_POST['m_id'].'order by m.id_m asc LIMIT 0, 30 '; 

$id_m = $_GET['id_m'];

$sql = 'SELECT m.id_m As id , m.name_m As name , m.idcard_m As idcard , m.address_m As address , m.rdate_m As rdate , '
        . ' v.id_village As village , v.village As vill , '
        . ' s.id_status As status , s.status As sta , '
        . ' w.id_welfare As welfare , w.welfare As wel '
        . ' FROM member m INNER JOIN village v ON m.id_village = v.id_village '
        . ' INNER JOIN status s ON m.id_status = s.id_status '
        . ' INNER JOIN welfare w ON m.id_welfare = w.id_welfare
           WHERE m.id_m=$id_m'
        . ' asc LIMIT 0, 30 '; 

$sql = 'SELECT m.id_m AS id , m.name_m AS name , m.idcard_m AS idcard , m.address_m AS address , '
        . ' m.rdate_m AS rdate , '
        . ' v.id_village AS village , v.village AS vill , '
        . ' s.id_status AS status , s.status AS sta , '
        . ' w.id_welfare AS welfare , w.welfare AS wel '
        . ' FROM member m , village v , status s , welfare w '
        . ' WHERE m.id_welfare = w.id_welfare and m.id_village = v.id_village 
          and m.id_status = s.id_status and m.id_m =4 '// แทนค่าตัวแปรด้วยตัวเลข จาก $id_m 
        . ' ORDER BY m.id_m ASC LIMIT 0, 30 ';
