我正在使用 csv 解析在我的 sql 中导入 csv 文件。我在 Mysql 中的表很少。我想在所有表中导入 csv 文件一次。所以我使用了下面的脚本。在那个国家可以进口，但状态表没有显示以下错误
csv_spliter.py:74: Warning: Incorrect integer value: ''country_id'' for column 'id' at row 1
row)
csv_spliter.py:74: Warning: Incorrect integer value: ''0'' for column 'id' at row 1

csv_spliter.py:74: Warning: Incorrect integer value: ''3'' for column 'id' at row 1
