Question

I’m trying to modify the two database files used by Google Drive to redirect my sync folder via a script (snapshot.db and sync_conf.db). While I can open the files in certain sqlite browsers (not all) I cant get python to execute a query. I just get the message: sqlite3.DatabaseError: file is encrypted or is not a database

Apparently google is using a Write-Ahead-logging (WAL) configuration on the databases and it can be turned off by running PRAGMA journal_mode=DELETE; (according to sqlite.org) against the database, but I can’t figure out how to run that against the database if python can’t read it.

heres what I have (I tried executing the PRAGMA command and commiting and then reopening but it didnt work):

import sqlite3

snapShot = 'C:\Documents and Settings\user\Local Settings\Application Data\Google\Drive\snapshot.db'
sync_conf = 'C:\Documents and Settings\user\Local Settings\Application Data\Google\Drive\sync_config.db'
sync_folder_path = 'H:\Google Drive'

conn = sqlite3.connect(snapShot)

cursor = conn.cursor()
#cursor.execute('PRAGMA journal_mode=DELETE;')
#conn.commit()
#conn= sqlite3.connect(snapShot)
#cursor = conn.cursor()
query = "UPDATE local_entry SET filename = '\\?\\" + sync_folder_path +"' WHERE filename ='\\?\C:Users\\admin\Google Drive'"
print query
cursor.execute(query)

problem solved. I just downloaded the latest version of sqlite from http://www.sqlite.org/download.html and overwrote the old .dll in my python27/DLL directory. Works fine now.

What a nusance.
