composite primary key

913578Jun 26 2012 — edited Jun 27 2012

Hi,

I am just confusing in understanding composite primary key.

I know what is composite key and how it stores the data.. but i am not able to find when i have to choose the columns to be composite keys.

Can you please give me a simple scenario to understand this.

Thanks,
Vinod
