SQLite Forum

Clear shared memory DB and backup problem
If the Python interface that you want is not available in pysqlite2 (sqlite3 wrapper) because it only pretends "minimal commonality" and only allows access to features which are available in every other db-api wrapper.  pysqlite2 does not support features of sqlite3 that are not common with DB2, Postgres, MySQL, and SQL Server.

If you want something for Python that will allow access to SQLite3 as if it were SQLite3 then the use of a wrapper that is not limited to the "minimal common db-api" interface and exposes the entire functionality of SQLite3 may be perspicacious.
