Question

Since BerkeleyDB can use the SQLite api, can python use sqlite module to connect to BerkeleyDB.

This post suggests using something else, but could have been written pre-Api sync.
Best Python module for Berkeley DB?

Can get a simple connection string. If there known problem, PLEASE post. I am exploring this topic.

Using python 2.7 on linux and windows.

I’ve tried on linux x86_64 with python27, here the steps to make a static version since
I doubt your distribution has bdb sqlite api.

Download db-5.2.36.tar.gz

tar xzvf db-5.2.36.tar.gz
cd db-5.2.36/build_unix/
CFLAGS="-fPIC" ../dist/configure --enable-static --disable-shared --enable-sql-compat
# you need -fPIC to build the python ext of pysqlite
make
make prefix=/tmp/bdb install

get a copy of pysqlite2 from http://code.google.com/p/pysqlite/, I’ve used an hg checkout.
In setup.cfg add in build_ext section (there are yet two commented lines you can reuse them)

include_dirs=/tmp/bdb/include
library_dirs=/tmp/bdb/lib

then cd in pysqlite:

python setup.py build
python setup.py install

or without installing:

cd build/lib.linux-x86_64-2.7
python
from pysqlite2 import dbapi2
conn = dbapi2.connect('test.db')
c = conn.cursor()
c.execute('bla bla bla sql')
