Is there an annotation to define a multi column index in jpa2?

No, as hinted in my answer to your previous question there is no standardized way, you have to use provider extensions for that (when they exist).

1 just curious to know, as per your earlier suggestion we are using hibernate annotations for this purpose. It makes sense to support this, when JPA already has support for single column Index annotation. Just my 2 cents – user339108 Sep 20 '10 at 10:48 @user339108 I personally agree and I'd like JPA to support this too.

Maybe in a future version. – Pascal Thivent Sep 20 '10 at 11:42 @user339108 Can you provide an example to your statement "JPA already has support for single column Index annotation". I couldn't find any annotation allowing this other then the @Index annotation provided by – jaxvy Oct 28 '10 at 17:54.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
