(closed) Delete Company or reset full database to install backup?

[christopher]

I hope someone can give me hint.
I made some tests with the import of a few companies using the addon developed by cape-it.
The addon works great, but i made a mistake and prepared a csv that was not utf-8.
Now i have 4 companies n my database that i want to delete.

How can i, (manually) delete those customers? There is no ticket or setting linked to them. So i think it should be safe.

Alternative:
I created (of course) a backup before i made those tests. But i cant use restore.pl on a non-empty database.
Is there some script to first delete everything and than use the restore.pl?

To be able to restore, simply login to your DB and do a drop database followed by a create database.

Thanks for the feedback, got a clean database again.
