Create table in Redshift through db_query() in Python

$

I'm trying to create a table in Redshift using db_query() with the following code:

snapshot_date = '20240325'sql = """create table tablename""" + snapshot_date +""" as (select * from tablename)"""data = db_query('redshift', sql)

And I'm getting the following error:

TypeError                                 Traceback (most recent call last)<ipython-input-3-ff895c5014e5> in <module>      3 """      4 ----> 5 data = db_query('redshift', sql)~/premium-analysis/notebooks/../src/data/db_connect.py in db_query(db_name, query, conn_kwargs, verbose, load_file, save_file, params, chunk_size, **kwargs)    161     162         if params is None:--> 163             df = sql_query(conn, query, **kwargs)    164     165         else:~/premium-analysis/notebooks/../src/data/db_connect.py in sql_query(conn, query, params, **kwargs)    234     """    235     try:--> 236         df = pd.read_sql(query, conn, params=params, **kwargs)    237         return df    238 ~/anaconda3/lib/python3.8/site-packages/pandas/io/sql.py in read_sql(sql, con, index_col, coerce_float, params, parse_dates, columns, chunksize)    600     601     if isinstance(pandas_sql, SQLiteDatabase):--> 602         return pandas_sql.read_query(    603             sql,    604             index_col=index_col,~/anaconda3/lib/python3.8/site-packages/pandas/io/sql.py in read_query(self, sql, index_col, coerce_float, params, parse_dates, chunksize, dtype)   2115         args = _convert_params(sql, params)   2116         cursor = self.execute(*args)-> 2117         columns = [col_desc[0] for col_desc in cursor.description]   2118    2119         if chunksize is not None:TypeError: 'NoneType' object is not iterable

I understand db_query is used to iterate over the resultset. Is there any way I can use it to create a table and not return a resultset?
