Solve the following python programming problem given the following code:
@ pytest.fixture (scope = 'function', params = ['test.db', pytest.mark.mysqltest (pytest.config.option.mysql)]) 
def db(request) : 
    param = request.param 
    def clean() : 
        session = jip.db.create_session () 
        session.close () 
        engine = jip.db.engine 
        engine.execute (jip.db.InputFile.__table__.delete ()) 
        engine.execute (jip.db.OutputFile.__table__.delete ()) 
        engine.execute (jip.db.job_dependencies.delete ()) 
        engine.execute (jip.db.job_groups.delete ()) 
        engine.execute (jip.db.job_pipes.delete ()) 
        engine.execute (jip.db.Job.__table__.delete ()) 
        engine.execute ('ALTER TABLE jobs AUTO_INCREMENT = 1') 
if ('mysql' in request) : 
        request.addfinalizer (clean) 
return param
