我正在尝试使用pythonmysql在两个日期之间从mysql数据库中获取记录，但是遇到了raiseerrorclass，errorvalue
下面是我的代码，请让我知道我哪里做错了

request_date = parse(from_date) #2018-06-01 00:00:00
parsed_from_date = request_date.strftime("%Y-%m-%d %X")

request_date1 = parse(to_date) #2018-06-04 00:00:00
parsed_to_date = request_date1.strftime("%Y-%m-%d %X")
query_string = 'SELECT * FROM test_inof where test_image = %s and  test_readydate_time>=%s and test_readydate_time<=%s'
if(area):
    query_string = query_string + " and area = ' " +  area +  " ' "
if(team):
    query_string = query_string + " and team =' " + team + " ' " 
t = testInfo.objects.raw(query_string,[image,str(parsed_from_date), str(parsed_to_date)])

错误是：

File "c:\users\dasarr\appdata\local\temp\easy_install-flprbl\MySQL_python-1.2.5-py2.7-win32.egg.tmp\MySQLdb\connections.py", line 36, in defaulterrorhandler raise errorclass, errorvalue
