從腳本導入Mysql

Question

我在我的sql中使用csv解析導入csv文件。我在Mysql中有幾張表。我想在所有表中導入csv文件一次。所以我使用下面的腳本。在那個國家能夠導入，但狀態表中沒有顯示它我下面的錯誤

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

任何一個可以給我一些意見，我該怎麼辦呢？

Answer 1

在將數據轉儲到數據庫之前，您是否將字符串轉換爲整數？

我認爲這就是Incorrect integer value錯誤信息的來源。
