Support turbodbc

[pmetzner]

Currently only python 2.7 is supported by turbodbc and therefore for sqlalchemy-exasol, too.

Humble request: Since turbodbc now supports Python 3, can sqlalchemy-exasol extend the turbodbc support to Python 3, too?

I have activated the tests for turbodbc and python 3.4. There are three errors, but they do not seem to be critical:

Did you try to use/install sqlalchemy with turbodbc and got any errors on python 3.x?

[pmetzner]

Awesome! Already tested it yesterday, this works like a charm:

cnxn = connect(dns)
crsr = cnxn.cursor()
crsr.execute('select 42')
crsr.fetchall()

[pmetzner]

Ah, I think I misread your question. I tried installing sqlalchemy-exasol[turbodbc] yesterday but it didn't offer the extra turbodbc. Now it did and it works. Did you change anything?

[pmetzner]

I had some trouble with the DEFAULT_DRIVER_NAME in turbodbc.py, I hotfixed it in #57.

Could you specify the problems you are having with the DEFAULT_DRIVER_NAME ?
As EXAODBC is the default driver name provided by EXASOL and their driver package and you can overwrite it in you connection string I do not see a problem so far.

[bjoernmeier]

I close this ticket as python3 support is fixed and the default driver name can be overwritten.
