Question

我知道对此错误代码已经提出了一些问题，但是在我的情况下，查询正在对我的测试文件进行处理，但是在转换为flask方法之后，它给了我一个错误我正在研究烧瓶，我的任务是在给定日期之间创建和下载特定用户的excel 我的烧瓶方法代码如下

@app.route('/excel_sheet')
def mk_excel_sheet():

    sort_user = request.args.get('sort_user2', 'abc1')
    from_date = request.args.get('from_date2', 'abc2')
    to_date = request.args.get('to_date2', 'abc3')
    company_name = session.get('company_name', 'abc4')

    print(f"{sort_user}\n{from_date}\n{to_date}\n{company_name}")

    file_name = f"{sort_user}-{from_date[:2]}-{from_date[3:5]}-{from_date[6:10]}-{to_date[:2]}-{to_date[3:5]}-{to_date[6:10]}.xlsx"
    print("file_name = ",file_name)
    file_path = 'static/'+str(file_name)
    print("file_path = ", file_path)
    #print(from_date, to_date)

    cur = connn.cursor()

    query = """

        book = xlsxwriter.Workbook(file_path)
        sheet = book.add_worksheet('sheet 1')

        book.close()

    except Exception as e:

    except Exception as e:
        print("FILE ERROR = ",e)

我得到ERROR = 1054 (42S22): Unknown column 'company_name' in 'field list' 什么是我的mysql查询中的字段列表我不知道为什么，因为查询在正常的test.py文件中工作所以有人可以指出我做错了吗

错误= 1054（42S22）：“字段列表”中的未知列“ company_name”
