I'm exporting data out of some gp tables on a regular basis. I would like to do this incrementally. However there doesn't seem to be any consistency with any sort of timestamp column. Some columns have a dex_row_ts column. Some have a modifdt, but in many cases that date is not the same as dex_row_ts. Some tables have no modified date at all. I don't suppose there's a table that can be joined that might have this last-modified info?
