PyDbLite 2.3

PyDbLite is a pure-Python in-memory database engine, using Python list comprehensions as query language, instead of SQL

It consists of one small module, PyDbLite.py. The package also provides two modules, SQLite.py and MySQL.py. They use SQLite and MySQL backends with the same Pythonic syntax as the pure-Python PyDbLite engine

Quick example :

from PyDbLite import Base

db = Base(‘dummy’)

db.create(‘name’,’age’,’size’)

db.insert(name=’homer’,age=23,size=1.84)

db.commit()

recs = [ r for r in db if 30 > r[‘age’] >= 18 and r[‘size’] < 2 ]

recs = db(key1=val1,key2=val2)

db.update(record,age=24)

db.delete(record)
