handling.

SSL Connections
------------------

The PyMySQL DBAPI accepts the same SSL arguments as that of MySQLdb,
described at :ref:`mysqldb_ssl`.   See that section for additional examples.

If the server uses an automatically-generated certificate that is self-signed
or does not match the host name (as seen from the client), it may also be
necessary to indicate ``ssl_check_hostname=false`` in PyMySQL::

    connection_uri = (
        "mysql+pymysql://scott:tiger@192.168.0.134/test"
        "?ssl_ca=/home/gord/client-ssl/ca.pem"
        "&ssl_cert=/home/gord/client-ssl/client-cert.pem"
        "&ssl_key=/home/gord/client-ssl/client-key.pem"
        "&ssl_check_hostname=false"
    )

MySQL-Python Compatibility
--------------------------

The pymysql DBAPI is a pure Python port of the MySQL-python (MySQLdb) driver,
and targets 100% compatibility.   Most behavioral notes for MySQL-python apply
to the pymysql driver as well.
