How to Insert Image in SQLite using Python?

16 May, 2021
In this article, we will discuss how to insert images in SQLite using sqlite3 module in Python.
1. Set the connection to the SQLite database using Python code.
sqliteConnection = sqlite3.connect('SQLite_Retrieving_data.db')
cursor = sqliteConnection.cursor()
2. We need to define an INSERT query for inserting the BLOB data into the table.  
sqlite_insert_blob_query = """ INSERT INTO Student
                                 (name, img) VALUES (?, ?)"""
3. Converting human-readable file into binary data by calling this convertToBinaryData() function, and storing it empPhoto variable,
empPhoto = convertToBinaryData(photo)
4. Once the file converted into binary format, now let’s convert data into tuple format,
data_tuple = (name, empPhoto)
5. Use cursor.execute() to execute a SELECT query in Python.  
cursor = sqliteConnection.cursor()
cursor.execute(sqlite_insert_blob_query, data_tuple)
6. Use sqliteConnection.commit() for saving the changes we made.  
sqliteConnection.commit()
7. Create a function that converts Human Readable data into the binary format for storing it into database.  
def convertToBinaryData(filename):

  # Convert binary format to images or files data
  with open(filename, 'rb') as file:
      blobData = file.read()
  return blobData
8. Close the cursor connection and MySQL database.
if sqliteConnection:
    sqliteConnection.close()
    print("the sqlite connection is closed")
Below is the implementation.
Python3
import sqlite3    # Function for Convert Binary Data # to Human Readable Formatdef convertToBinaryData(filename):          # Convert binary format to images     # or files data    with open(filename, 'rb') as file:        blobData = file.read()    return blobData    def insertBLOB(name, photo):    try:                  # Using connect method for establishing        # a connection        sqliteConnection = sqlite3.connect('SQLite_Retrieving_data.db')        cursor = sqliteConnection.cursor()        print("Connected to SQLite")                  # insert query        sqlite_insert_blob_query = """ INSERT INTO Student                                  (name, img) VALUES (?, ?)"""                  # Converting human readable file into         # binary data        empPhoto = convertToBinaryData(photo)                  # Convert data into tuple format        data_tuple = (name, empPhoto)                  # using cursor object executing our query        cursor.execute(sqlite_insert_blob_query, data_tuple)        sqliteConnection.commit()        print("Image and file inserted successfully as a BLOB into a table")        cursor.close()      except sqlite3.Error as error:        print("Failed to insert blob data into sqlite table", error)          finally:        if sqliteConnection:            sqliteConnection.close()            print("the sqlite connection is closed")  insertBLOB("Smith", "D:\Internship Tasks\GFG\images\One.png")insertBLOB("David", "D:\Internship Tasks\GFG\images\person.png")
Output:

Let’s check output in the database using SELECT query with proper format commands,
