ชื่อฟิลด์เหมือนกัน แต่คนล่ะตาราง จะใช้ mysql_fetch_array รูปแบบยังไง

$sql="select job.job_id,job.job_fname,job.job_detail,job.job_tel,job.job_status,job.job_remark,job.job_tel,

$result=mysql_db_query($dbname,$sql);
$rs=mysql_fetch_array($result);
$job_date=$rs[job_date];
$y=substr($job_date,2,2);
