Why does the client need to generate a key for the database?
The server should return this to the client instead.

In the windows world there exists a globally unique identifier called
GUID. The GUID is guaranteed to be unique on all machines.
It is a combination of the MAC address + Current Time + some other
things.
The idea is that the no. should be unique when generated on any
machine at any time!
You can generate such a unique no. easily on the client side.

However, i would advise against clients generating Unique IDs for
database keys.
