In debug mode Flask-SQLAlchemy will log all the SQL queries sent
    to the database.  This information is available until the end of request
    which makes it possible to easily ensure that the SQL generated is the
    one expected on errors or in unittesting.  If you don't want to enable
    the DEBUG mode for your unittests you can also enable the query
    recording by setting the ``'SQLALCHEMY_RECORD_QUERIES'`` config variable
    to `True`.  This is automatically enabled if Flask is in testing mode.

    The value returned will be a list of named tuples with the following
    attributes:

    `statement`
        The SQL statement issued

    `parameters`
        The parameters for the SQL statement

    `start_time` / `end_time`
        Time the query started / the results arrived.  Please keep in mind
        that the timer function used depends on your platform. These
        values are only useful for sorting or comparing.  They do not
        necessarily represent an absolute timestamp.

    `duration`
        Time the query took in seconds

    `context`
        A string giving a rough estimation of where in your application
        query was issued.  The exact format is undefined so don't try
        to reconstruct filename or function name.
