使用psychopg2更新PostgreSQL中包含值列表的列的行

Question

我有一个带有列噪声的表环境，我需要更新噪声列中的所有行，并带有值列表，new_dB_values_list和len（new_dB_values_list）= no。的行。 我的代码是这样的：

PsqlCon = psycopg2.connect(host="xx.xxx.xxx.xx", dbname='all_green', user='xxxx' , password='yzzxxx')
con = PsqlCon.cursor()
con.execute("""UPDATE environment SET noise new_dB_values_list;""")

我做错了什么，正确的方法是什么。感谢。

获取错误：
