>How can I compare a historical table with a current table to see if the current table's memo field has changed? Is there a select statement that will do this? thanks in advance.
Sure you can do this, if you have a field, or field combination, that serves as a primary key.
I guess it would go more or less like this:
select OldTable.MyMemo, NewTable.MyMemo;
from OldTable join NewTable on OldTable.PK = NewTable.PK;
where OldTable.MyMemo # NewTable.MyMemo;
into cursor Tmp
I would also suggest to use an audit trail, i.e., any change in any table goes to an audit table, i.e., a table of changes. You should record: what record in what table was changed; who did the change; and when. My introductory article on this topic may give you some ideas. Universal Thread Magazine, May 2003.
