Thanx Ferozz for your quick response.

I had one more question if i dnt have primary key for that table than wat is the solution for this kind of problem.
I read from link you provide ..in that it is necessary for a class it must have primary identifier.
so can u tell me if i dnt have primary identifier for that class.

Thanks Ferozz for your quick response.

I had one more question
If i dnt have any primary key ...primary identifier for that class than wat is the solution to skip this chek.

Is their any mechanism to avoid id identifier.

u should always have primary key in table, because it can caused a lot of problem for you later.

eventually u can claim one of your property which has always unique value as id, but table without primary key is pretty stupid idea
