我有一个CSV文件 7万个记录 我需要比较日期
目前储存的如DD/MM/YYYY
我认为,Sqlite要求他们储存YYYY-MM-DD,以便我能使用日期功能。
是否有任何简单的方法可以转换所有这些记录的格式?
非常感谢
Get something like Notepad++/ textpad 并进行搜索和替换 :
Textpad ([0-9]{2})/([0-9]{2})/([0-9]{4})
Notepad++ ([0-9]{2})/([0-9]{2})/([0-9]{4})
Replace with: 3-2-1
确保您以正则表达式/扩展搜索重新搜索
您是否尝试过 strftime (%Y-%m-%d, colName here) 吗?
