Many Sculpture users have some confusions when they try to work with the beta version of Oracle support in Sculpture 2.1.
There are two tricks you must keep in mind while you try to access your Oracle database from Sculpture.
1. You must switch your database type to Oracle:
Select the diagram surface and from the properties window change 'Database Type' to 'Oracle'.

2. Remove the Unicode keyword from the generated connection string:
Ensure that your connection string does not have this term 'Unicode=True'.
