I know that Pypyodbc is the newer version of Pyodbc. A question before asked about the comparison between these two but I want to add Pymssql into the mix.
回答1:
As of December 2019:
pyodbc is under active development, is officially supported by Microsoft (when using the current version of Microsoft's ODBC Driver for SQL Server), and has a couple of Microsoft employees contributing bug fixes and new features that relate to accessing SQL Server and Azure SQL.
pypyodbc came along after pyodbc but is not "the newer version of Pyodbc", it is an alternative pure-Python implementation. It has not seen an official release since January 2017.
pymssql lost a lot of momentum and has been discontinued.
