ODBC "DB Error: not supported"

I'm trying to move a web application from the development environment (Linux/Apache/MySQL) to the production environment (Windows2000/IIS/ODBC[SqlServer]) and I'm encountering the following error when I try a query:

"DB Error: not supported"

I'm using PEAR:

B and PHP 4.3.3
We just installed the PEAR libraries using go_pear.bat and it seemed to install just fine.

Here is the code... it is a login script that
either authenticates the user or sends them back
to the index.php page to try again:

php Code:

Original - php Code

<?php
require_once( "DB.php" ); 
require_once( "dconfig.php" ) ;
$db =& DB::Connect( $dsn ) ; // , array() );
print "<html><head>testpage</head><body><pre>n" ;
if (PEAR::isError($db)) { 
//    header("Location: index.php?e=01") ;
    $str = "Location: index.php?e=01&" . $db->getMessage()  ;
    header("Location: index.php?e=01&" . urlencode($db->getMessage()) ) ;
    exit ;
} else {
    $db->setFetchMode(DB_FETCHMODE_ASSOC) ;
    if ( isset($_POST['useremail']) and isset($_POST['userpass']) ) {
        $SQL = " SELECT id, isadmin FROM users WHERE email = ? and password_string = ? " ;
        $STMT = $db->prepare( $SQL ) ;
        $res =& $db->execute( $STMT, array($_POST['useremail'],$_POST['userpass']) ) ;
        if (PEAR::isError($res)) {
            // query failed
            header("Location: index.php?e=02") ;
            exit;
        }else{   
            if ( $res->numRows() == 1 ) {
                if ( $res->fetchinto($row) ) {
                    session_start() ;
                    $_SESSION['userid'] = $row['id'] ;
                    $_SESSION['isadmin'] = $row['isadmin'] ;
                    // Authenticated user.... proceed
                    header("Location: welcome.php") ;
                    exit ;
                }else{

                    exit;
                }
            }elseif ( $res->numRows() > 1 ) {
                // multiple records - needs admin to fix
                print "num rows: " . print_r($res->numRows()) . "n" ;
                // header("Location: index.php?e=04" ) ;

RE: ODBC "DB Error: not supported"

Hummmm, so "save" is not the same as "preview" :-)
Anyway, any help is appreciated - I'm at a loss.

Tnx
Eric

RE: ODBC "DB Error: not supported"

Reviewing the notes I've made I realize this may be helpful. The error occurs when I execute the $res->numRows() method. Tracing it back to the DB.php file is of no help... it's just the function that handles the error but no clue as to what caused it. Also, $res is a db_error object but for some reason the PEAR::isError($res) test does not detect it... it waits until the numRows() > 1 test so I end up at the
header("index.php?e=04" line in my code instead of the "?e=02" line.

Thanks
Eric
