buzhug syntax doesn't use SQL statements, but a more Pythonic syntax :
from buzhug import Base
db = Base('foo').create(('name',str),('age',int))
# simple queries
# complex queries
print [ rec.name for rec in db if age > 30 ]
I made a few speed comparisons with Gadfly, KirbyBase (another pure-
Python DB, not maintained anymore) and SQLite. You can find the
results on the buzhug home page : http://buzhug.sourceforge.net
The conclusion is that buzhug is much faster than the other pure-
Python db engines, and (only) 3 times slower than SQLite
