Python实现将MySQL数据库查询结果导出到Excel

import pymysql

connection = pymysql.connect(
    host='localhost',
    user='root',
    password='123456',
    database='caiwu'
)

query = "SELECT * FROM report_品名"

import xlsxwriter

workbook = xlsxwriter.Workbook('output.xlsx')
worksheet = workbook.add_worksheet()

cursor = connection.cursor()
cursor.execute(query)

column_names = [i[0] for i in cursor.description]

import datetime

data = cursor.fetchall()

for col_index, col_name in enumerate(column_names):
    worksheet.write(0, col_index, col_name)

for row_index, row_data in enumerate(data):
    for col_index, col_data in enumerate(row_data):
        if isinstance(col_data, datetime.datetime):
            col_data = col_data.strftime("%Y-%m-%d %H:%M:%S")
        worksheet.write(row_index + 1, col_index, col_data)

cursor.close()
connection.close()
workbook.close()

import pymysql
import xlsxwriter
import datetime

# 建立数据库连接
connection = pymysql.connect(
    host='localhost',
    user='root',
    password='123456',
    database='caiwu'
)

# 编写SQL查询语句
query = "SELECT * FROM report_品名"

# 创建Excel文件对象
workbook = xlsxwriter.Workbook('output2.xlsx')

# 创建Excel工作表对象
worksheet = workbook.add_worksheet()

# 创建游标对象
cursor = connection.cursor()

# 执行SQL查询
cursor.execute(query)

# 获取查询结果的列名
column_names = [i[0] for i in cursor.description]

# 将列名写入Excel文件的第一行
for col_index, col_name in enumerate(column_names):
    worksheet.write(0, col_index, col_name)

# 获取查询结果中的数据
data = cursor.fetchall()

# 将数据写入Excel文件中
for row_index, row_data in enumerate(data):
    for col_index, col_data in enumerate(row_data):
        # 判断数据类型是否为时间类型
        if isinstance(col_data, datetime.datetime):
            col_data = col_data.strftime("%Y-%m-%d %H:%M:%S")  # 将时间字段转换为字符串
        worksheet.write(row_index + 1, col_index, col_data)

# 关闭游标对象
cursor.close()

# 关闭数据库连接
connection.close()

# 关闭Excel文件对象
workbook.close()
