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

.. note::

    The PyODBC for MySQL dialect is **not tested as part of
    SQLAlchemy's continuous integration**.
    The recommended MySQL dialects are mysqlclient and PyMySQL.
    However, if you want to use the mysql+pyodbc dialect and require
    full support for ``utf8mb4`` characters (including supplementary
    characters like emoji) be sure to use a current release of
    MySQL Connector/ODBC and specify the "ANSI" (**not** "Unicode")
    version of the driver in your DSN or connection string.

Pass through exact pyodbc connection string::

    import urllib

    connection_string = (
        "DRIVER=MySQL ODBC 8.0 ANSI Driver;"
        "SERVER=localhost;"
        "PORT=3307;"
        "DATABASE=mydb;"
        "UID=root;"
        "PWD=(whatever);"
        "charset=utf8mb4;"
    )
    params = urllib.parse.quote_plus(connection_string)
    connection_uri = "mysql+pyodbc:///?odbc_connect=%s" % params
