Heroku convert .mdb to csv or how to use multiple buildpacks together

Question

Have a simple python application deployed on heroku and I need to manage with microsoft access database (.mdb). I read, that I have to use mdb-tools for this purposes. Example - converting mdb database to csv:

bash: mdb-export 'mdb-file' 'table-name' > result.csv (I am going to run it as subprocess in python)

I installed https://github.com/iblogbox/heroku-buildpack-mdbtools build pack. But when I try test it:

heroku run bash
mdb-export

I get bash: mdb-export: command not found

Questions:

• Can I use multiple buildpacks in heroku?
• Is it possible to convert .mdb file to csv or excel file in linux?

Thank you!

Here is answer:

You don't need heroku-buildpack-mdbtools to use several buildpacks in your heroku application.

Following this arcticle ( https://devcenter.heroku.com/articles/using-multiple-buildpacks-for-an-app ) You can use following

bash: heroku buildpacks:set your-first-buildpack

then

bash: heroku buildpacks:add --index 1 your-additional-buildpack

I used heroku/python + https://github.com/profit-strategies/heroku-buildpack-mdbtools to convert .mdb database (WHO STILL USES MICROSOFT ACCESS IN 2016???) to csv in linux by this command: mdb-export 'mdb-file' 'table-name' > result.csv Just runned this command as a subprocess in python

subprocess.call("mdb-export '%s' 'colorado well completions' > Temporary/result.csv" % path_to_mdb, shell=True)
