My application (VB) uses Oracle 8i.
Recently it has been upgraded to Oracle 9i.
Now we are having a problem with the application while retriving the date fields which are null. It gives an error -"22007 - Invalid Date format". But earlier we never this error. We are able to retrieve null date fileds from the SQL prompt.
When Oracle is upgraded to 9i, do we have to change any parameters or code of the application?
