Frequently, a database sequence is used to generate a unique numeric value for use as a primary key.

from other threads, I'm assuming your using MSAccess. The 'Sequence' functionality Bear mentioned above can also be accomplished in MSAccess. Just set the column you want as the primary key's data type to 'AutoNumber'. As an autonumber field, you never insert or update values in it. Access does everything for you.
 
I agree. Here's the link: http://zeroturnaround.com/jrebel - it saves me about five hours per week
