Integers cannot be passed as Bind Parameter on Python 3 (MS Access)

See original GitHub issue

See this SA question for details: http://stackoverflow.com/q/20240130

I can reproduce this issue on Windows 10, Python 3.5 32bit, pyodbc 3.0.10. Converting integers to floats before passing them to execute is a work around (as stated in the second answer in the SA question).

@SpringsTea - This issue was fixed in 4.0.8 and then broken again in 4.0.25. See #509 for the current status.

@gordthompson, I think those logs support my theory that the issue is in Python 3 all integers are longs so they are being bound to SQL_BIGINT which isn’t supported by Access.

It seems that there needs to be a condition in GetLongInfo() that will set info.ParameterType to SQL_INTEGER if the driver does not support SQL_BIGINT or (perhaps simpler) if the number is small enough to fit in an SQL_INTEGER.

I have not written any C/C++ in over 10 years but I might try my hand at a fix.
