ทำ Select LEFT JOIN ข้อมูลที่ออกมา ไม่ออกทางซ้ายเลยค่ะ

<?php

include("conn.php") ;
$sql = "SELECT subject.s_id , student.student_id , student.s_id , student.date , student.point FROM subject LEFT JOIN student USING(s_id) WHERE student.student_id = student2";
$sqlquery = mysql_db_query($dbname, $sql); 
?>
<table width="90%" border=0  cellpadding=4 align=center>
<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
</table>
<table width="50%" cellspacing="1" cellpadding="0" align="center">
<tr>
				<td height="35" bgcolor="#FFE4E1"><DIV align="center"><span class=style5>#</span></div></td>
				<td height="35" bgcolor="#FFE4E1"><DIV align="center"><span class=style5>s_id</span></div></td>

						$i++;

				?>
			<tr bgcolor="<?=$bg;?>">
