Data Fetching from MySQL don’t Fetch newly add Data while Running the Script

I’m Working on a Real-time Data Mirroring From MySQL to PostgreSQL

I’m using Python for that kinda project.

Code works Just fine but,

The Problem is when I keep it running it’s only updating old data but don’t Add new Records that been added to MySQL Database

here’s Full Code.

import timeimport pyodbcimport psycopg2import mysql.connector# Connect to MySQLmysql_conn = mysql.connector.connect(    host="localhost",    user="root",    password="******",    database="ShagufTask")# Connect to PostgreSQLpg_conn = psycopg2.connect(host="localhost", database="ShagufSecondTask", user="postgres", password="******")def mirror_data():    try:        # Retrieve data from MySQL        mysql_cursor = mysql_conn.cursor()        mysql_query = "SELECT id, name, city, revenue FROM myapp_shaguftask"        mysql_cursor.execute(mysql_query)        data_to_mirror = mysql_cursor.fetchall()        # Insert or update data into PostgreSQL        pg_cursor = pg_conn.cursor()        for row in data_to_mirror:            pg_cursor.execute("SELECT id FROM shaguftable WHERE id = %s", (row[0],))            existing_record = pg_cursor.fetchone()            if existing_record:                pg_cursor.execute("UPDATE shaguftable SET name = %s, city = %s, revenue = %s WHERE id = %s",                                  (row[1], row[2], row[3], row[0]))                print("Data Updated")                print(row[0])            else:                pg_cursor.execute("INSERT INTO shaguftable (id, name, city, revenue) VALUES (%s, %s, %s, %s)", row)                print("Data Inserted")                print(row[0])        # Commit changes        pg_conn.commit()        print("Data mirroring completed successfully.")    except Exception as e:        print("An error occurred:", str(e))# Continuously run the mirroring scriptwhile True:    mirror_data()    # Sleep for a specified interval before fetching new data again    time.sleep(10)  # Sleep for 1 minute before fetching new data

I think the Problem that it’s not Capable of reading new Records while it’s Running but I don’t know how to Solve this Problem
