Databases and PHP

I am trying to use PHP inner join through ODBC with access database. Here is my php coding : <?php$excelFile = realpath('../db/feedback.mdb');$excelDir = dirname($excelFile);$conn = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};DriverId=790;Dbq=$excelFile;DefaultDir=$excelDir" , '', ''); if (!$conn) {exit("Connection Failed: " . $conn);} $rs=odbc_exec($conn,"SELECT friends.friendName,friends.Online FROM friends inner join chat on (friends.username='ankit') and (friends.username=chat.username or friends.username=chat.email) WHERE friends.online='Offline' and (friends.friendName like '%a%' or friends.friendEmail like '%a%')"); if (!$rs) {exit("Error in SQL");}while (odbc_fetch_row($rs)) { echo odbc_result($rs,1) . " "; echo odbc_result($rs,2) . " "; echo odbc_result($rs,3) . " "; echo "<br>"; }odbc_close($conn);?> Here is the ERROR: Warning: odbc_exec() [function.odbc-exec]: SQL error: [Microsoft][ODBC Microsoft Access Driver] Join expression not supported., SQL state S1000 in SQLExecDirect in D:\wamp\www\ALL_IN_ONE\wwwroot\index.php on line 9Error in SQL Any help would be much appreciated. _________________________________________________________________ Log on to MSN India for a lowdown on what’s hot in the world today http://in.msn.com
