Can you rollback a DELETE statement?

I was wondering if you can roll back a delete statement since they were said to be a permanent change, though if it was not yet committed, can it be rolled back..

As a rule, you can't rollback data that you have deleted. But it's a little complicated depending on which version of SQL you're using. The transaction syntax might be a little different

Here's a bit more detail. :-)
