How do I best delete bulk records in 7.2 Professional?

We've been doing some testing of importing of Accounts, Contacts, and Leads into our SugarCRM install. We need to do a hard delete on all records we imported plus any related data (I do not know what this covers)

It would be nice to have a near clean working database again with nothing we imported. Has anyone had this requirement and have a good solution to the problem?


I've used the sql below but is it enough?

# Removing leads import
TRUNCATE TABLE leads;
TRUNCATE TABLE leads_audit;
TRUNCATE TABLE leads_cstm;
TRUNCATE TABLE prospect_lists_prospects;

# Removing Contacts import
TRUNCATE TABLE contacts;
TRUNCATE TABLE contacts_audit;
TRUNCATE TABLE contacts_bugs;
TRUNCATE TABLE contacts_cases;
TRUNCATE TABLE contacts_cstm;
TRUNCATE TABLE contacts_users;

I would like to be able to remove as much junk as possible without breaking anything.
