.. dialect:: mysql+pyodbc
    :name: PyODBC
    :dbapi: pyodbc
    :connectstring: mysql+pyodbc://<username>:<password>@<dsnname>
    :url: http://pypi.python.org/pypi/pyodbc/

    .. note:: The PyODBC for MySQL dialect is not well supported, and
       is subject to unresolved character encoding issues
       which exist within the current ODBC drivers available.
       (see http://code.google.com/p/pyodbc/issues/detail?id=25).
       Other dialects for MySQL are recommended.
