I guess that's a symptom of the ibm_db_sa package not being very well tested with pyodbc
I'm very confused by pyodbc's version numbers - https://pypi.python.org/pypi/pyodbc/3.0.10 suggests that version 3.0.10 exists and was uploaded on 2015-04-29, but also says that the latest version is 2.1.9, which was uploaded on 2015-09-24. I've never used pyodbc so don't know what to make of that. I assume your error is coming from this line: https://github.com/ibmdb/python-ibmdbsa/blob/master/ibm_db_sa/ibm_db_sa/base.py#L696 ...which is in the base dialect, rather than the pyodbc-specific bit. Maybe you could hack around the problem by setting a "dbms_ver" attribute on the pyodbc connection that you are creating in your custom creator function. This is where it gets used: https://github.com/ibmdb/python-ibmdbsa/blob/master/ibm_db_sa/ibm_db_sa/base.py#L481 Simon On Fri, Feb 19, 2016 at 5:00 PM, Alex Hall <ah...@autodist.com> wrote: > That makes more sense, but as soon as I put "+pyodbc" in, I'm back to > last week's "pyodbc.Connection object has no attribute dbms_ver" > error.
