How to edit database - remove code?

[Num85]

I inserted this SQL code into my oscommerce database through phpmyadmin:

 

INSERT INTO configuration SET configuration_title='Set "Contact Us" Email List', date_added=NOW(), sort_order='11', configuration_group_id='1', configuration_key='CONTACT_US_LIST', configuration_value= '', configuration_description='On the "Contact Us" Page, set the list of email addresses , in this format: Name 1 <email@address1>, Name 2 <email@address2>', use_function = NULL , set_function = NULL;

 

How can I remove this code from my database without affecting the rest of it?
