title: Create table during joomla module installation
body: <p>i'm currently working on a joomla module (using joomla 2.5), and I have to create a table to use it.</p>
  
  <p>i follow this tutorial : <a href="http://docs.joomla.org/J2.5:Creating_a_simple_module/Developing_a_Basic_Module" rel="nofollow noreferrer">http://docs.joomla.org/J2.5:Creating_a_simple_module/Developing_a_Basic_Module</a> but when i install it, the table is not created.</p>
  
  <p>here is my xml file :</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;extension type="module" version="2.5.0" client="site" method="upgrade"&gt;
  &lt;name&gt;Valid Order Module&lt;/name&gt;
  &lt;author&gt;Mathiewz&lt;/author&gt;
  &lt;version&gt;1.0.0&lt;/version&gt;
  &lt;description&gt;Module de validation des commandes !&lt;/description&gt;
  &lt;files&gt;
      &lt;filename module="mod_valid_order"&gt;mod_valid_order.php&lt;/filename&gt;
      &lt;filename&gt;index.html&lt;/filename&gt;
      &lt;filename&gt;helper.php&lt;/filename&gt;
      &lt;filename&gt;search.php&lt;/filename&gt;
      &lt;filename&gt;export_gc.php&lt;/filename&gt;
      &lt;folder&gt;tmpl&lt;/folder&gt;
      &lt;folder&gt;img&lt;/folder&gt;
      &lt;folder&gt;sql&lt;/folder&gt;
  &lt;/files&gt;
  
  &lt;install&gt;
      &lt;sql&gt;
          &lt;file driver="mysql"&gt;sql/install.sql&lt;/file&gt;
      &lt;/sql&gt;
  &lt;/install&gt;
  &lt;update&gt;
      &lt;sql&gt;
          &lt;file driver="mysql"&gt;sql/install.sql&lt;/file&gt;
      &lt;/sql&gt;
  &lt;/update&gt;
  &lt;uninstall&gt;
      &lt;sql&gt;
          &lt;file driver="mysql"&gt;sql/uninstall.sql&lt;/file&gt;
      &lt;/sql&gt;
  &lt;/uninstall&gt;
  &lt;config&gt;
  &lt;/config&gt;
  &lt;/extension&gt;

  <p>i tried my sql request on phpmyadmin directly and it works, so i presume the problem is in the xml file</p>
