instead of using below thing
cursor_ppm.execute(primary_query)
    logging.info(f"executed primary query - {primary_query}")
    query_info = f"-- ++++++++++++++++++++|PRIMARY_QUERY\n"
    query_info += f"-- #Query:\n{primary_query};\n"
    write_sql(query_info)

    rows = cursor_ppm.fetchall()
    columns = [desc[0] for desc in cursor_ppm.description]
can you modify code like use pd_read_sql
