pratial reset of database?

[firben]

Hello,

I have installed a contribution, that i regret.

Now i want to restore the database, as it was before.

Can somebody help?

The SQL querty i installed was this:

ALTER TABLE products_attributes ADD sort_order INT DEFAULT '50' NOT NULL; 
ALTER TABLE products_attributes ADD COLUMN attribute_sort INT UNSIGNED NOT NULL DEFAULT '0';

 

Can anybody make a code that can undo the above query?

 

Thank you in advance.
