Joomla!2.5 not executing SQL files upon install/update - joomla2.5

Question

My SQL files aren't being executed when I install or update a new component. Initially I found it weird that my workmate needed to execute his SQL files directly into PHPMyAdmin, but isn't Joomla! supposed to automatically run the files?
Here's how I set up my XML:
ReforcoDigital.xml
<?xml version="1.0" encoding="utf-8"?>
<extension type="component" version="2.5.0" client="site" method="upgrade">
<name>Reforco Digital</name>

</install>

</schemas>
</update>
<files folder="site">
<folder>language</folder>

<filename>controller.php</filename>
<filename>index.html</filename>
</files>
<administration>
<menu>Reforco Digital</menu>
<files folder="admin">
<folder>sql</folder>

<filename>controller.php</filename>

<filename>index.html</filename>
</files>
</administration>
</extension>
Folder admin/sql has the install.mysql.utf8.sql file, and admin/sql/updates/mysql has the file 0.1.sql; both have the very same SQL code. What am I possibly missing here?

Answer 1

The fact that I was updating my component with a 0.1.sql over and over was the problem. Changed the filename to 0.2.sql and it did the job.
My understanding is that Joomla! will look for the update files in alphabetical order, and judge if that version has been used or not; correct me if that's wrong. Since there was a higher version than 0.1, it did the job.

Answer 2

I commented earlier that I was having the same problem as you, but I'm not. Mine is a completely different problem that I'll describe after I explain what's happening with your file.
So, your sql folder resides within your admin component folder (this is normal), but your install/uninstall sql XML entries don't describe this. So, I believe that if you make this change, you'll find it working as expected:
<install>
<sql folder="admin">
<file driver="mysql" charset="utf8">sql/install.mysql.utf8.sql</file>
</sql>
</install>
My problem is that the update section will only execute a schema update when a schema exists in the #__schema table - and install.sql isn't executed on update. So if you're upgrading your extension and adding a table to it, you can't really rely on the XML installer to create your new table unless your extension already had tables before the update.
I'm going with an install.php file to search for and create the table if necessary.
