How would you distihguish 2 records with the same key than?

>Okay, sorting is done by id, field2, then time. The computer does the sort past that. I think Null comes before not null fields. Id and field2 will never be Null for this situation. And yes there can be more then 1 record per period with Null.

>>>The table I am moving around is built from 10 other tables. This was being done in vfp by getting the built table into a recordset and then looping through it and building the records by hand and inserting them one by one. Since there is ~250000 that goes done to ~94500 records in vfp, and takes about 30 minutes. We thought putting the select and build into a SP, we could speed up the process.
