What i'm doing wrong? 我做错了什么？ This file was a export from a query, then i delete all records and try to import. 此文件是从查询导出，然后我删除所有记录并尝试导入。

The flat file import task will default lengths to VARCHAR(50) . 平面文件导入任务的默认长度为VARCHAR(50) 。 You need to go to the Advanced property of the flat file connection page and change the length manually to match the destination table. 您需要转到平面文件连接页面的“高级”属性，并手动更改长度以匹配目标表。 There should also be an option to Suggest Types which may match the metadata that you're using, but it does a sampling of rows from the file so it may not be as accurate as just setting types manually. 建议类型也应该有一个选项可以匹配您正在使用的元数据，但它会对文件中的行进行采样，因此它可能不如仅手动设置类型那样准确。

It may be that you're trying to import data from the CSV which is too large for the field you're importing it in to. 您可能正在尝试从CSV中导入数据，这对于您要导入的字段来说太大了。 Perhaps you need to increase the size of your fields in your SQL table? 也许您需要增加SQL表中字段的大小？

Have you tried to import a single, very small line of data from the CSV to see if that works? 您是否尝试从CSV导入一个非常小的数据行，看看它是否有效？ If it does, excessively large data somewhere in the rest of the sheet may be the problem. 如果是这样的话，在表格的其余部分某处可能存在过大的数据。
