    rows = cursor.fetchall()
    columns = [desc[0] for desc in cursor.description]
    df = pd.DataFrame(rows, columns=columns)

so in the above code im passing connection, cursor = connect_to_database(encrypt, host, port, user, db_type, schema) insetad of that i want to pass complete json_data in which i have like below
"PPM_PC": {
		"DB_PASSWORD": "tibtcare_ppm",
		"DB_TYPE": "MYSQL",
		"DB_PORT": "3308",
		"DB_SCHEMA": "tibtcare_ppm",
		"DB_USER": "tibtcare_ppm",
		"DB_HOST": "10.16.16.128",
		"ENCRYPT": "N"
	},
so all the arguments must be passed and want to return connection,cursor,schema from the function connect_to_database
