所以我试图使用for循环从python字典输入数据到postgres数据库.看看代码

for value in dic:
    domain_desc = value["domain_desc"]
    commodity_desc = value["commodity_desc"]
    statisticcat_desc = value["statisticcat_desc"]
    agg_level_desc = value["agg_level_desc"]
    country_name = value["country_name"]
    state_name = value["state_name"]
    county_name = value["county_name"]
    unit_desc = value["unit_desc"]
    value1 = value["Value"]
    year_val = value["year"]
    cur.execute("INSERT INTO fact_data (domain_desc,commodity_desc,statisticcat_desc,agg_level_desc,country_name,state_name,county_name,unit_desc,value,year) VALUES (domain_desc,commodity_desc,statisticcat_desc,agg_level_desc,country_name,state_name,county_name,unit_desc,value1,year_val)")
    cur.commit()
    print("Success!")

我一直在收到错误

回溯(最近一次调用最后一次):文件"C:/Users/Backup/PycharmProjects/gro-app/harvest.py",第123行,在cur.execute中("INSERT INTO fact_data(domain_desc,commodity_desc,statisticcat_desc,agg_level_desc,country_name) ,state_name,county_name,unit_desc,value,year)VALUES(domain_desc,commodity_desc,statisticcat_desc,agg_level_desc,country_name,state_name,county_name,unit_desc,value1,year_val)")psycopg2.ProgrammingError:列"domain_desc"不存在第1行:. ..te_name,county_name,unit_desc,value,year)VALUES(domain_des ... ^提示:表"fact_data"中有一个名为"domain_desc"的列,但不能从查询的这一部分引用它.

我把数据库和表放在正确的位置.导致此错误的原因是什么？我找到了一个类似的问题,但我不理解错误,它在不同的背景下有人帮助我理解这一点
