This is the code I tried:

Code:
# Configuration
DELETE from configuration_group WHERE configuration_key = DISPLAY_NEWS_SUMMARY;
DELETE from configuration_group WHERE configuration_key = DISPLAY_NEWS_SUMMARY_DAYS;
DELETE from configuration_group WHERE configuration_key = DISPLAY_NEWS_SUMMARY_LENGTH;
DELETE from configuration_group WHERE configuration_key = NEWS_COMMENTS_REQUIRE_CUSTOMER;
DELETE from configuration_group WHERE configuration_key = ENTRY_NEWS_NAME_MIN_LENGTH;
DELETE from configuration_group WHERE configuration_key = ENTRY_NEWS_COMMENTS_MIN_LENGTH;
DELETE from configuration_group WHERE configuration_key = NEWS_COMMENTS_EMAIL_ADMIN_NOTICE;
DELETE from configuration_group_id WHERE configuration_group_title = "News & Articles Management";
# Table structure for table news_articles 
DROP TABLE IF EXISTS news_articles;

# Table structure for table news_articles_text
DROP TABLE IF EXISTS news_articles_text;

# Table structure for table news_authors
DROP TABLE IF EXISTS news_authors;

# Table structure for table news_comments
DROP TABLE IF EXISTS news_comments;

# Table structure for table news_comments_description
DROP TABLE IF EXISTS news_comments_description;
Comes back with this message:

1054 Unknown column 'configuration_key' in 'where clause'
in:
[DELETE FROM configuration_group WHERE configuration_key = DISPLAY_NEWS_SUMMARY;]
