Python 2.7 如何使用python脚本将Mysql表数据导出到excel文件？

我一直在尝试使用Python2.7.8将该数据从表导出到excel文件，但没有成功。请帮帮我。我的要求是从表中导出数据并将其存储在本地（windows C驱动器）

这可能是不用Python就可以轻松完成的事情，但这里有一个框架结构。注意，这会写入.csv文件，而不是Excel文件。您可以使用

xlwt

库来完成后者

请注意，您需要先

pip安装MySQL-python

，这通常是无痛的，但也很简单

编辑-这应该会将其写入Excel，但我对

xlwt

不是很熟悉，而且我还没有测试过这段代码

import MySQLdb
from xlsxwriter.workbook import Workbook

user = '' # your username
passwd = '' # your password
host = '' # your host
db = '' # database where your table is stored
table = '' # table you want to save

con = MySQLdb.connect(user=user, passwd=passwd, host=host, db=db)
cursor = con.cursor()

query = "SELECT * FROM %s;" % table
cursor.execute(query)

workbook = Workbook('outfile.xlsx')
sheet = workbook.add_worksheet()
for r, row in enumerate(cursor.fetchall()):
    for c, col in enumerate(row):
        sheet.write(r, c, col)

他写道：

import mysql.connector
from openpyxl import Workbook

def main():

    # Connect to DB -----------------------------------------------------------
    db = mysql.connector.connect( user='root', password='', host='127.0.0.1')

    SQL = 'CREATE DATABASE IF NOT EXISTS ' + database + ';'
    cur.execute(SQL)
    db.commit()

    SQL = 'USE ' + database + ';'
    cur.execute(SQL)

    # Create car data ---------------------------------------------------------

非常感谢你。这对我来说很有效，但我的要求是将表格数据导出到Excel文件，我已经为其编写了代码。请帮帮我，我已经试过了。如果有帮助，请向上投票和/或选择我的答案。@jgysland:我尝试了你的代码，但看不到任何导出的文件：（你知道为什么吗？@ihue:你找不到该文件？你在执行脚本的同一目录中查找了吗？请确保关闭工作簿，否则它可能不会保存它。最后是“workbook.close（）”。添加此选项可以为我保存它：）
