MySQL database question

[blakdeth77]

Is entering a statement to the Install SQL Patches input field and running it going to damage my database? I was suggested this command by another user here and he was unsure if this command would delete the GroupID 0 and cause harm to the original functionality of the web site. Can anyone clue me in as to whether this would cause my site to undergo an "epic failure"?

DELETE FROM `configuration` WHERE `configuration_group_id` = 0;
