Re: [IBMiOSS] IBM i python ibm_db_dbi example usage

Can anyone point me to a decent example that connects to the local IBMi DB2

mapping the connect method parameters.

That's the key. Once connected, Bob's your uncle. But how do you connect?

Right now, I'm in the same boat as you, using a Python Litmis Space.

John Yueng provided a nice example for iSeriesPython on his blog, but that
uses db2 rather than ibm_db

Thanks for the plug. iSeriesPython makes it simple whether you're
using db2 or ibm_db_dbi. As you've seen from the blog post,
db2.connect() doesn't require any parameters at all, if you're happy
with the default, which (sensibly enough) is to connect to the local
database using the credentials you're already logged in with.

The ibm_db_dbi that comes with iSeriesPython is not much more complicated:

connection = ibm_db_dbi.connect('*LOCAL')

While it's not needed, you could also use the same parameter for db2:

connection = db2.connect('*LOCAL')

But IBM's Python for PASE is not quite so simple. At least, I have not
yet been able to figure out the magic incantation to connect.
Hopefully Aaron or Kevin can chime in here.
