I'm a newbie and trying to get my head around all of this. If I do a fill on a BO like the Following:" Select * from stock where 1 = 2" and do a BO.Count it is obviously 0 even though the table has 100 records. That is OK but why when I do BO.Save() does all of the records remain? I think it has to do with no changes in BO but if I really want to remove all of the previous records in the table what is the quickest way? No relationships to worry about just a table that hold previous data and now needs to get all new data???? TIA.
