unixODBC error on MacOS

[lthibault]

Hello, I'm attempting to connect to an in-memory SQLite database in the following manner.

import asyncio
import aioodbc

DB_CONNSTR = "Driver=SQLite;Database=:memory:"

async def run_db_loop(q):
    conn = await aioodbc.connect(dsn=DB_CONNSTR, loop=loop)

loop.run_until_complete(run_db_loop(queue.async_q))

This produces the following error on macOS Sierra v10.12.6:

~/.pyenv/versions/3.6.2/lib/python3.6/site-packages/aioodbc/connection.py in _connect(dsn, autocommit, ansi, timeout, loop, executor, echo, **kwargs)
     43                       timeout=timeout, echo=echo, loop=loop, executor=executor,
     44                       **kwargs)
---> 45     await conn._connect()
     46     return conn

     57             self.future.set_exception(e)

Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib 'SQLite' : file not found (0) (SQLDriverConnect)")

Prior to running the script I performed brew install unixodbc.

Any idea what might be going on here?

Hi I never tested on macs but I think idea is the same, you have to install .so odbc compatible driver for sqlite and update your system odbcinst.ini, we do this in tests for mysql (looks like sqlite driver registers itself there during install)
