Reproduce pysqlite's row_factory on apsw

With these it helps Disclosure: I am the author of APSW
Yes, very easily. APSW has something called a row tracer documented at http://apidoc.apsw.googlecode.com/hg/execution.html#tracing
s[str(row.wbcode)+str(row.Year)]=float(row[query_name])

import sqlite3 with Python2.7 on Heroku

With these it helps This isn't possible on Heroku, as sqlite requires a permanent writable file system. Since Heroku does not provide a permanent writable file system, sqlite3 won't work.
Something to consider: Heroku is a distributed environment. This means an application may run on many machines within many processes. In your case, this would generate multiple sqlite3 instances (each running locally), were it permitted.

Python2.7 - Sqlite3 - 2 inputs

With these it helps You get this error because the first argument is actually the file name.
A simple test file shows how this works:
[~]$ cat test.py
from sys import argv

if __name__ == '__main__':
    print argv
    print len(argv)
[~]$ python test.py one two
['test.py', 'one', 'two']
3
[~]$ python test.py one
['test.py', 'one']
2
query = "INSERT OR REPLACE INTO user VALUES(?,?)"
cursor.execute(query,[na,ha])
conn.commit()

joining across databases with sqlite3 / pysqlite

Hope this helps You can attach additional databases with ATTACH DATABASE:
conn = sqlite3.connect('data.db')
conn.execute('ATTACH DATABASE details.db AS details')
cursor = conn.cursor()
cursor.execute('''
    select details.A.colA
    from main.A
    join details.A using ('key')
    where main.A.colB = 0 and main.A.colC = 1
    ''')

APSW (or SQLite3) very slow INSERT on executemany
