I have to import building information from another system. I've decided to
keep track of each set of data downloaded by including a Download_Date. That
way I keep historical data.
My table has 25 fields in addition to Download_Date.
My question. I'd like the user to be able to find differences between
downloads. The primary key on the table is Building_ID and Download_Date.
I'd like a user to be able to select two values for Download_Date on a form
and then have the records based on Building_ID show up in a listbox if there
are any differences. So I'd probably have two listboxes, one showing the
record for the newer Download_Date and one for the older Download_Date.
So how do I code this. I need to be able to find differences in any field.
If different values for any field for the same Building_ID are found between
the download_dates, then display that record in one of the listboxes.
Also, what if a new Building_ID shows up or one disappears.
Ideas are appreciated.
