There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
One thing here is that we are not going to encrypt all columns and only few columns will be encrypted and those doesn't need to decrypt as per my requirement.

I wouldn't ! Ellliptic Curve Cryptography is slow compared to AES which is the industry standard.

Well, readers can refer to this document from Oracle, who apparently has a different view, and decide which is best. See link.
A couple of noteworthy quotes:
"The Elliptic Curve Cryptosystem
(ECC), offers the highest strength per bit of any known
public-key cryptosystem today."
"We repeated these experiments using 2048-bit RSA keys
and 193-bit ECC keys. We found ECC to perform better
than RSA without any exceptions, "
For a bit more recent document, if the above is too dated for you, I would refer to this 2010 abstract.
A noteworthy quote from this document is:
"From the above we conclude that, computationally speaking,
cracking 160-bit ECC is at least three orders of magnitude
harder than cracking 1024-bit RSA. "
Or, perhaps this presentation, given by QualComm in Nov 2012. See page 10 for speed comparisons.

Richard Tookey wrote:R. Grimes presented an argument that ECC was superior to RSA but since I was not advocating RSA as the primary encryption algorithm the argument was irrelevant.
R. Grimes wrote:Oh, I'm sorry. I thought that, in your post I was responding to, you said:
"Even then I would probably use RSA rather than ECC since RSA is ubiquitous and ECC is not (at this time) ."
