Mass delete old orders from Oscommerce/MarvikShop

After copied my old database from Oscommerce to the new MarvikShop/Joomla. I want to delete some old orders. Of course you can delete them one by one. But I want mass delete.

So I found this oscommerce add-on

addons.oscommerce.com/info/6924

did some changes in the file. Link to the right database.

for me adding j17_osc_... database table. For other people it could be mcyuk_osc_


Of course do a BACKUP of your whole database!!!

After that run it directly by calling the URL.

that's it!
