I'm using the Microsoft-Oracle ODBC Driver to access an Oracle database in MS Access, but on about half of my linked tables, I get a [Function Sequence Error] whenever I try to pull up the Datasheet view. I've looked around for alternative drivers, but no luck.
Does anyone know how to stop getting these function sequence errors? And if I need a new driver, could you provide a link if possible to a download site? Thanks
I figured it out. The problem was that the Microsoft-Oracle ODBC driver mistakenly converted Oracle's CLOB (Character Large Object) fields into mere Text[255 char] fields in Access. And then Access freaked out whenever it tried to render these CLOBS with more than 255 characters.
So I just excluded those CLOB fields from all my queries and migration tables. It does mean that I can't migrate over fields like "Description" or "Notes," but at least I can migrate over the primary keys and relationships. That's good enough for me, for now.
