อยากทราบวิธีการอัพข้อมูลที่ถูกแก้ไขลง SQL ที่ละหลายๆ Table ทำยังไงหรอครับ

	$strSQL = "UPDATE child SET child_ID = '".trim($_POST['txtchild_ID'])."',child_fname = '".trim($_POST['txtchild_fname'])."',child_lname = '".trim($_POST['txtchild_lname'])."',child_sex = '".trim($_POST['txtchild_sex'])."',child_bd = '".trim($birth)."',child_bld = '".trim($_POST['txtchild_bld'])."',child_cond = '".trim($_POST['txtchild_cond'])."',child_allrg = '".trim($_POST['txtchild_allrg'])."' WHERE(child_ID LIKE '%".$_GET["child_ID"]."%')";
		$objQuery = mysql_query($strSQL);
		
	$strSQL = "UPDATE father SET f_ID = '".trim($_POST['txtf_ID'])."',f_fname = '".trim($_POST['txtf_fname'])."',f_lname = '".trim($_POST['txtf_lname'])."'f_nadd = '".trim($_POST['txtf_nadd'])."',f_sadd = '".trim($_POST['txtf_sadd']	)."',f_madd = '".trim($_POST['txtf_madd'])."',f_rdadd = '".trim($_POST['txtf_rdadd'])."',f_tadd = '".trim($_POST['txtf_tadd'])."',f_aadd = '".trim($_POST['txtf_aadd'])."',f_jadd = '".trim($_POST['txtf_jadd'])."',f_idadd = '".trim($_POST['txtf_idadd'])."',f_tel = '".trim($_POST['txtf_tel'])."',f_carr = '".trim($_POST['txtf_carr'])."',child_ID	= '".trim($_POST['txtchild_ID'])."' WHERE(child_ID LIKE '%".$_GET["child_ID"]."%')";
		$objQuery = mysql_query($strSQL);
