sqlitebck 1.0

Sqlite3 online backup API implementation.

Single function that allows to save any sqlite3 database one to another. You can use this for example for loading and dumping memory database (:memory:) into file (alternative to iter dump functionality).

See the Sqlite3 C API docs for more info.

Build and installation

Now you can build or install sqlitebck using distutils:

$ python setup.py install

Tests

Nothing big, just test basic functionality:

$ python tests.py

Usage example

Basic usage example - memory database saved into file:

>>> import sqlite3
>>> conn = sqlite3.connect(':memory:')
>>> curr = conn.cursor()

# create table and put there some data
>>> curr.execute('CREATE TABLE foo (bar INTEGER)')
<sqlite3.Cursor object at 0xb73b2800>
>>> curr.execute('INSERT INTO foo VALUES (123)')
<sqlite3.Cursor object at 0xb73b2800>
>>> curr.close()
>>> conn.commit()
>>> import sqlitebck

# save in memory database (conn) into file
>>> conn2 = sqlite3.connect('/tmp/in_memory_sqlite_db_save.db')
>>> sqlitebck.copy(conn, conn2)
>>> conn.close()
>>> curr2 = conn2.cursor()

# check if data is in file database ;)
>>> curr2.execute('SELECT * FROM foo');
<sqlite3.Cursor object at 0xb73b2860>
>>> curr2.fetchall()
[(123,)]

If you want to load file database into memory, just call:

>>> sqlitebck.copy(conn2, conn)
