This allows, for instance, to run a database that +is compatibile with SQL2000 while running on a SQL2005 database +server. ``server_version_info`` will always retrun the database +server version information (in this case SQL2005) and not the +compatibiility level information. Because of this, if running under +a backwards compatibility mode SQAlchemy may attempt to use T-SQL +statements that are unable to be parsed by the database server. + Known Issues ------------ |
