Displaying Data from MySQL table

We defined my_conn as connection object Collect the data from student_profile table by using SQLALchemy.

my_conn = create_engine("mysql+mysqldb://userid:password@localhost/database_name")
try:
    my_row=my_conn.execute("SELECT id,student,profile_photo FROM student_profile WHERE id=1")
    student = my_row.fetchone()

Here we used student to collect data. Here is the code to display student id and name.

# displaying student id on Button 
b1=tk.Button(my_w,text=student[0])
b1.grid(row=1,column=1)
# displaying student name over button
b2=tk.Button(my_w,text=student[1])
b2.grid(row=1,column=2)

Managing image display.

import io
from PIL import Image, ImageTk

#collecting image and displaying 
img = Image.open(io.BytesIO(student[2]))
img = ImageTk.PhotoImage(img)
b2 =tk.Button(my_w,image=img) # using Button 
b2.grid(row=2,column=1)

l2 = tk.Label(my_w,image=img) # using Label 
l2.grid(row=2,column=2)

Full code is here

import tkinter  as tk 
from tkinter import * 
import io
from PIL import Image, ImageTk
my_w = tk.Tk()
my_w.geometry("400x250") 
from sqlalchemy import create_engine
from sqlalchemy.exc import SQLAlchemyError
my_conn = create_engine("mysql+mysqldb://userid:password@localhost/database_name")
try:
    my_row=my_conn.execute("SELECT id,student,profile_photo FROM student_profile WHERE id=1")
    student = my_row.fetchone()
except SQLAlchemyError as e:
  error=str(e.__dict__['orig'])
  print(error) 
# displaying student id on Button 
b1=tk.Button(my_w,text=student[0])
b1.grid(row=1,column=1)
# displaying student name over button
b2=tk.Button(my_w,text=student[1])
b2.grid(row=1,column=2)
#collecting image and displaying 
img = Image.open(io.BytesIO(student[2]))
img = ImageTk.PhotoImage(img)
b2 =tk.Button(my_w,image=img) # using Button 
b2.grid(row=2,column=1)
l2 = tk.Label(my_w,image=img) # using Label 
l2.grid(row=2,column=2) 
my_w.mainloop()
