用python从mysql查询生成excel文件

我正在制作一个excel文件，类似于报告我的代码，如下所示

import mysql.connector
import xlwt
from xlsxwriter.workbook import Workbook

connn = mysql.connector.connect(user='root',password='root',host='localhost',port='3306',database='attendence')

company_name = 'MCC-INDIA'
sort_user = 'MCCuser0036'
from_date = '01-04-2019'
to_date = '27-04-2019'

cur = connn.cursor()

query3 = "SELECT type, username, time_in, address_in, time_out, address_out FROM (SELECT 'attendence' AS 'type', user AS 'username', company_name AS 'cn', STR_TO_DATE(in_time, '%d-%m-%Y %H:%i:%s') AS 'time_in', in_address AS 'address_in', STR_TO_DATE(out_time, '%d-%m-%Y %H:%i:%s') AS 'time_out', out_address AS 'address_out' FROM attendence UNION ALL SELECT 'visit', username, company_name, STR_TO_DATE(visit_time_in, '%d-%m-%Y %H:%i:%s'), location_in, STR_TO_DATE(visit_time_out, '%d-%m-%Y %H:%i:%s'), location_out FROM visits) t WHERE t.username = '"+str(sort_user)+"' AND t.cn = '"+str(company_name)+"' AND time_in BETWEEN STR_TO_DATE('"+str(from_date)+"', '%d-%m-%Y %H:%i:%s') AND STR_TO_DATE('"+str(to_date)+"', '%d-%m-%Y %H:%i:%s') ORDER BY time_in ASC;"


try:
    cur.execute(query3)
    #data = cur.fetchall()
    book = xlwt.Workbook('record.xlsx')
    sheet = book.add_sheet('sheet 1', cell_overwrite_ok=True)
    aaa = 1

    sheet.write(0,0,'TYPE')
    sheet.write(0,1,'USERNAME')
    sheet.write(0,2,'TIME IN')
    sheet.write(0,3,'LOCATION IN')
    sheet.write(0,4,'TIME OUT')
    sheet.write(0,5,'LOCATION OUT')


    r = 2

    for r, row in enumerate(cur.fetchall()):
        r+=1
        for c, col in enumerate(row):
            sheet.write(r, c, col)

    book.save('record.xlsx')

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

当我通过不同的python运行mysql查询以查看输出时，我看到的是

('attendence', 'MCCuser0036', datetime.datetime(2019, 4, 1, 15, 29, 8), '736, Aala Hazrat Rd, Jagruti Nagar, Nehru Nagar, Kurla East, Mumbai, Maharashtra 400071, India', None, '')
('visit', 'MCCuser0036', datetime.datetime(2019, 4, 1, 15, 55, 45), '736, Aala Hazrat Rd, Jagruti Nagar, Nehru Nagar, Kurla East, Mumbai, Maharashtra 400071, India', None, '')
('attendence', 'MCCuser0036', datetime.datetime(2019, 4, 11, 15, 17, 56), 'Kokri Agar Road, Koliwada, Kokri Agar, Sion, Mumbai, Maharashtra 400037, India', None, '')
('attendence', 'MCCuser0036', datetime.datetime(2019, 4, 23, 17, 41, 5), 'Kokri Agar Road, Koliwada, Kokri Agar, Sion, Mumbai, Maharashtra 400037, India', datetime.datetime(2019, 4, 23, 17, 42, 54), 'Kokri Agar Road, Koliwada, Kokri Agar, Sion, Mumbai, Maharashtra 400037, India')

我不知道为什么要在第三列或索引位置2处输入datetime.datetime

当我试着看那个专栏的时候

2019-04-01 15:29:08
2019-04-01 15:55:45
2019-04-11 15:17:56
2019-04-23 17:41:05

有人能指出我做错了什么吗 我认为在尝试将mysql查询转换为python时出现了问题，但找不到

我的excel看起来像

---

可能

STR\u TO\u DATE

返回的是

datetime

对象，而不是

STR

。尝试调用将

datetime

对象转换为字符串，然后将其写入所需文件。

在

字段中键入的
time\u可能是
date
，因此
mysql
库会自动将其转换为python

一个快速的解决方案云将取代
工作表。将（r，c，col）
写入如下内容：

sheet.write(r, c, col if type(col) is not datetime else col.strftime('desired format here))

有关日期格式的详细信息，请参见

hello@olinox我忘了提到字段中的time_是varcharhello@Pythia我相信str_to_date是mysql的函数，我曾经将in_time和out_time列转换为date以进行比较，因为这两列也是varchar
