BDB used directly without some kind of interface does not support SQL.
The MySQL server is an interface to BDB.  When you use BDB tables in
MySQL, you're not interacting with BDB directly.

You're making the mistake of interpreting a statement on the Berkeley DB
Web site as though it was posted on the MySQL Web site.
