pymssql is currently not included in SQLAlchemy's continuous integration
(CI) testing.
-Modern versions of this driver worked very well with SQL Server and FreeTDS
-from Linux and were highly recommended. However, pymssql is currently
-unmaintained and has fallen behind the progress of the Microsoft ODBC driver in
-its support for newer features of SQL Server. The latest official release of
-pymssql at the time of this document is version 2.1.4 (August, 2018) and it
-lacks support for:
-
-1. table-valued parameters (TVPs),
-2. ``datetimeoffset`` columns using timezone-aware ``datetime`` objects
- (values are sent and retrieved as strings), and
-3. encrypted connections (e.g., to Azure SQL), when pymssql is installed from
- the pre-built wheels. Support for encrypted connections requires building
- pymssql from source, which can be a nuisance, especially under Windows.
-
-The above features are all supported by mssql+pyodbc when using Microsoft's
-ODBC Driver for SQL Server (msodbcsql), which is now available for Windows,
-(several flavors of) Linux, and macOS.
