Even lookup is not easy to be done securely. You don't want that a malicious server/database knows that you are accessing always that record.
See this discussion about how to achieve that: https://news.ycombinator.com/item?id=31668814
Up can't do a range on encrypted data. If you encrypt 5 and encrypt 10, how do you expect to compare the encrypted results to see which is greater?
If all you do is key value lookup then sure. But SQL is much richer than that.
