Ps. To prevent IE errors like 'File not found!' after downloading file from db I recommend to add next two lines into header:
header('Cache-Control: max-age=0');
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");

With this, IE will open any file normally :)

I'll give you example how to download a file from db without storing it on server's FS:
It works like this - point yor browser to index.php?name=file.ext
Just make sure that file "file.ext" exists in your db!

Code:

<?php

$dbConnection
=ocilogon('user','pass','data.world'); //login stuff
$sql_SelectBlob='select document_body,filename from tdocuments where id=1'; //selecting a blob field named 'document_body' with id = 1
$statement=OCIParse($dbConnection,$sql_SelectBlob);

OCIExecute($statement) or die($sql_SelectBlob.'<hr>');

if(
OCIFetch($statement)) //if file exists
{
$a=OCIResult($statement,"DOCUMENT_BODY");
}
header('Content-type: application/octet-stream;');
header('Content-disposition: attachment;filename='.$_GET['name']);

print
$a->load();
//browser promts to save or open the file
?>

Have fun!
