def get_debug_queries():
"""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.
