How to export Mysql Table data to excel file using python script?

Question

I have been trying to export that data from table to excel file using python 2.7.8 but I have not succeeded. Please help me. My Requirement is to export the data from the table and store it in local(windows C Drive).

#!/usr/bin/python
import smtplib
import base64
import os
import sys
import xlswriter
import xlwt
import datetime
import MySQLdb
from pyh import *
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
db = MySQLdb.connect("192.168.1.118","stp","stp","STP")
cursor = db.cursor()
query = ("""select * from stp_automation_output""")
cursor.execute(query)
myresults = cursor.fetchall()
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet("My Sheet")
#date_format = workbook.add_format({'num_format': 'd mmmm yyyy'})
bold = workbook.add_format({'bold': 1})
worksheet.write('A1','Sno',bold)
worksheet.write('B1','function_name',bold)
worksheet.write('C1','input1',bold)
worksheet.write('D1','input2',bold)
worksheet.write('E1','input3',bold)
worksheet.write('F1','Expected_output',bold)
worksheet.write('G1','Actual_output',bold)
worksheet.write('H1','Result',bold)
row = 1
col = 0
for Sno,function_name,input1,input2,input3,Expected_output,Actual_output,Result in (myresults):
  Sno = row[0]
  function_name = row[1]
  input1 = row[2]
  input2 = row[3]
  input3 = row[4]
  Expected_output = row[5]
  Actual_output = row[6]
  Result = row[7]
workbook.save()

This is probably something you can do more easily without using Python, but here's a skeleton structure. Note this writes to a .csv, not an Excel file. You can use the xlwt library to accomplish the latter.

Note you'll need to pip install MySQL-python first, which is usually painless but occasionally not painless.

import MySQLdb
import csv

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)

with open('outfile','w') as f:
    writer = csv.writer(f)
    for row in cursor.fetchall():
        writer.writerow(row)

EDIT — This should write it to Excel, but I'm not very familiar with xlwt and I haven't tested this code.

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)

@jgysland : I tried your code, and I couldn't see any file exported. :( Do you know why ?

jgysland Over a year ago

@ihue: you can't find the file? Did you look in the same directory from which the script was executed?

Make sure to close the workbook other wise it might not save it. "workbook.close()" at the end. Adding this allowed it to save it for me :)
