I am trying to connect to Oracle db using pyodbc, getting errors. The examples include ms sql server driver:

in my /etc/unixODBC/odbc.ini, I have this entry:

Description=data repository db

import pyodbc
cnxn=pyodbc.connect('DSN=test_con, UID=user_id, PWD=passwd123')

I get this error:

pyodbc.Error: ('IM012', '[IM012] [unixODBC][Driver Manager]DRIVER keyword syntax error (0) (SQLDriverConnect)')

Try something like:

import pyodbc
connectString = 'Driver={Microdsoft ODBC for Oracle};Server=<host>:<port>/<db>.<host>;uid= <username>;pwd=<password>'
cnxn = pyodbc.connect(connectString)
