This is part 1 of a 3-part question; the others are located at
(yes, I know they're out of order)
In the attached database, which is data retrieved from an ODBC-connected database to which I have read-only access, I can import the data shown in tblOrig. There are hundreds of IDNumbers; this is filtered data for one of them. Essentially, the table from which I am drawing this information lists every IDNumber, and revisions to it are shown in the Revision field, so the unique identifier of each record in the table is IDNumber & Revision.
What I would like to do is change the name of EditDate locally to StartDate, and add a column that says EndDate. I would like to automatically update the EndDate column when a new record is added to the table based on the StartDate; in other words, the preceding record of the filtered
data would get an EndDate of the new record's StartDate minus one day.
Part 2 of this question has to do with updating thousands of records in one fell swoop. Part 3 of this question has to do with a way to import the data since the last time I imported it and adding it to this table.
My Access coding skills are... rusty... so any assistance would be greatly appreciated.
