I am inserting value in a table in a database through query but it is giving some error as like this :-

Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘leave (session_id,empid,leave,year) values(’20202′, ‘DTL0009′, ’21′, ’2009′)’ at line 1

and the code for inserting these value is as i writing this code:-

$sqlquery = "insert into leave (session_id,empid,leave,year) values('$_SESSION[id]', '$_SESSION[empid]', '$_POST[leavenum]', '$_POST[year]')";
        $res = mysql_query($sqlquery,$link) or die('Error: ' . mysql_error());  

But i am receiving this error. I am unable to insert records in database. Please help me. How i can sort out this problem.
Thanks,
