if (Db::iserror ($conn))//error if connection is faulted
{
Print "Database connection failed";
}
$rs = $conn->query ("Select Id,username, password from tablename1"); Execute SQL statement
if (Db::iserror ($RS))//Determine if execution succeeded
{
Print "Data query failed";
}
while ($rs->fetchinto ($rows))//Loop output query Results
{
Print "No.: $rows [0]
";
Print "Name: $rows [1]
";
Print "Password: $rows [2]
";
Print "";
}
?>
