[Mod Edit: this question has been split off of the article: Uploading Files into MySql Database Using PHP]

I can't download.
I keep getting the following error:

Error! Query failed:
Query was empty

    <?php
    // Connect to the database
    $dbLink = mysql_connect("localhost","root","");
if (!$dbLink)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("filestorage", $dbLink);
     
    // Query for a list of all existing files
    $sql = 'SELECT `id`, `name`, `mime`, `size`, `created` FROM `file`';
     $result = mysql_query($query,$dbLink)
            or die("Error! Query failed: <pre>". mysql_error($dbLink) ."</pre>");
     
     
    // Check if it was successfull
    if($result) {
        // Make sure there are some files in there
        if($result->num_rows == 0) {
            echo '<p>There are no files in the database</p>';
        }
        else {
            // Print the top of a table
            echo '<table width="100%">
                    <tr>
                        <td><b>Name</b></td>
                        <td><b>Mime</b></td>
                        <td><b>Size (bytes)</b></td>
                        <td><b>Created</b></td>
                        <td><b>&nbsp;</b></td>
                    </tr>';
     
            // Print each file
            while($row = $result->fetch_assoc()) {
                echo "
                    <tr>

            }
     
            // Close table
            echo '</table>';

        //$result->free();
           mysql_free_result($result);
    }
    else
    {

        echo "<pre>{$dbLink->error}</pre>";

you initialized $sql but you passed $query query was definitely empty
