What we do here, is make one unique id(7963535) and use that record the placeholder of your current unique id number. Usually we have at least one date field, so use the date field to hold the next unique id number, and make the record that holds the unique id number have a unique id of 7963535 or something like that.

My experience with other db formats is that I could set that field to auto generate so that as each record is written it will increment the count by 1. we will be using this for cross referencing to some other files and must be unique. I know I can read through the file and increment a counter, but that seems to have a huge overhead, not to mention that as time goes on, it'll take longer and longer to calculate. Does anyone have a viable suggestion on how to accomplish this?
