error on second pyodbc.connect when using parameters, python 3.11, pyodbc 4.0.34 #1117

Closed avlis closed 1 year ago

Environment

To diagnose, we usually need to know the following, including version numbers. On Windows, be sure to specify 32-bit Python or 64-bit:

container based on python:3-slim

Issue

just checking out the new python 3.11, an old application of mine fails to establish the second connection to the same MS SQL server.

works every time if I send the connection parameters on a single string.

previous code: nc=pyodbc.connect(driver="{ODBC Driver 18 for SQL Server}", server=c["server"], database=c["database"], user=c["user"], password=c["password"],encoding = "UTF-8", trustservercertificate = c["trustservercertificate"] )

now only works if:

nc=pyodbc.connect('DRIVER={{ODBC Driver 18 for SQL Server}};SERVER={0};DATABASE={{{1}}};UID={{{2}}};PWD={{{3}}};ENCODING=UTF-8;TRUSTSERVERCERTIFICATE={4}'.format(c["server"], c["database"], c["user"], c["password"], c["trustservercertificate"] ))

ODBC trace:

PS: I can't explain the timestamps on the odbc trace, it looks like it's the first one that fails. But application wise, the flow is: test connection parameters, send a 'select @@version' to make sure it works <- this works try do do some stuff on new connection <- fails to create new connection

https://github.com/mkleehammer/pyodbc/issues/1095#issuecomment-1220793586 '34 comes with a very buggy old unixODBC, try a previous version of pyODBC to see if that's the cause of this too.

This doesn't make sense.

  • Python: 3.11.0 (main, Oct 25 2022, 05:00:36) [GCC 10.2.1 20210110] on linux
  • pyodbc: pyodbc-4.0.34-cp39-cp39-manylinux_2_24_x86_64.whl

That wheel won't install on Python 3.11:

ERROR: pyodbc-4.0.34-cp39-cp39-manylinux_2_24_x86_64.whl is not a supported wheel on this platform.

In any case

pip install --upgrade --force-reinstall pyodbc --no-binary pyodbc

should install the latest version of pyodbc from source.

not sure how it got there then... just using a standard container based on python:3-slim.

  ERROR: Failed building wheel for pyodbc

installing from source:

Step 16/20 : RUN pip3 install --upgrade --force-reinstall pyodbc --no-binary pyodbc
 ---> Running in 9c4820448bb9
DEPRECATION: --no-binary currently disables reading from the cache of locally built wheels. In the future --no-binary will not influence the wheel cache. pip 23.1 will enforce this behaviour change. A possible replacement is to use the --no-cache-dir option. You can use the flag --use-feature=no-binary-enable-wheel-cache to test the upcoming behaviour.

  DEPRECATION: pyodbc is being installed using the legacy 'setup.py install' method, because the '--no-binary' option was enabled for it and this currently disables local wheel building for projects that don't have a 'pyproject.toml' file. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/11451

and running the pyodbc.connect with each option as a parameter, instead of a single string parameter, will get me a " returned NULL without setting an exception" error on the second connection.

trying to install 3.0.32 from source will get a similar error to the one with the binary package.

gordthompson commented 1 year ago

pyodbc 4.0.34 does not have pre-built wheels for Python 3.11, so plain old pip install pyodbc builds from source:

After that, this code works:

cnxn = pyodbc.connect(
    driver="ODBC Driver 18 for SQL Server",
    server="192.168.0.199",
    user="scott",

print("First connect succeeded.")

Thanks to an amazing job by @keitherskine, new releases build official wheels now. There is an official 4.0.35 wheel available. Please try with that.
