Inserting and retrieving images into mysql through python

Question

I used this code to insert an image into mysql database and retrieve back the image. This code works perfectly with no errors , but the problem is even after inserting an image into img table , when I execute the command select * from img ; in the mysql command line it shows no records.

Table created in database;

create table img(images blob not null);

import mysql.connector
import sys
from PIL import Image
import base64
import cStringIO
import PIL.Image

db = mysql.connector.connect(user='root', password='abhi',
                              host='localhost',
                              database='cbir')

#image = Image.open('C:\Users\Abhi\Desktop\cbir-p\images.jpg')
with open("C:\Users\Abhi\Desktop\cbir-p\images.jpg", "rb") as image_file:
    encoded_string = base64.b64encode(image_file.read())

#blob_value = open('C:\Users\Abhi\Desktop\cbir-p\images.jpg', 'rb').read()
sql = 'INSERT INTO img(images) VALUES(%s)'    
args = (encoded_string, )
cursor=db.cursor()
cursor.execute(sql,args)
sql1='select * from img'
cursor.execute(sql1)
data=cursor.fetchall()
#print type(data[0][0])
data1=base64.b64decode(data[0][0])
file_like=cStringIO.StringIO(data1)
img=PIL.Image.open(file_like)
img.show()

db.close()

img.show()

db.close()

This code works fine

import mysql.connector
import base64
import io

import PIL.Image
with open('lemonyellow_logo.jpg', 'rb') as f:
    photo = f.read()
encodestring = base64.b64encode(photo)
db= mysql.connector.connect(user="root",password="lyncup",host="localhost",database="demo")
mycursor=db.cursor()
sql = "insert into sample values(%s)"
mycursor.execute(sql,(encodestring,))
db.commit()
sql1="select * from sample"
mycursor.execute(sql1)
data = mycursor.fetchall()
data1=base64.b64decode(data[0][0])
file_like=io.BytesIO(data1)
img=PIL.Image.open(file_like)
img.show()
db.close()
