推荐答案

您的导入确实存在两个主要问题:

You really have two major problems in your import:

错误0xc002f210:删除表SQL任务1:执行查询删除"表[dbo].[测试]失败，出现以下错误:无法删除表'dbo.test'，因为它没有存在或您没有权限.".

Error 0xc002f210: Drop table(s) SQL Task 1: Executing the query "drop table [dbo].[test] " failed with the following error: "Cannot drop the table 'dbo.test', because it does not exist or you do not have permission.".

似乎您正在尝试删除一个根本不存在的表.解决方案:只是不要这样做！

It seems like you're trying to drop a table that doesn't even exist. Solution: just don't do it!

错误0xc02020a1:数据流任务1:数据转换失败.数据列代码"的转换返回状态值4和状态文字文字被截断，或者一个或在中没有更多的字符匹配目标代码页.".

Error 0xc02020a1: Data Flow Task 1: Data conversion failed. The data conversion for column ""Code"" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".

您的代码"列显然比目标表中的结果列长.检查映射-可能这是一个非常长的字符串，并且SQL Server中VARCHAR列的默认长度太小.将目标列的数据类型更改为例如 VARCHAR(MAX)-给您2 GB的空间！那应该足够了...

Your column "Code" obviously is longer than the resulting column that you have in your target table. Check the mappings - maybe this is a very long character string, and the default length for the VARCHAR column in SQL Server is too small. Change the target column's data type to e.g. VARCHAR(MAX) - that gives you 2 GByte of space! That should be enough....

此外，代码"列似乎包含了您在SQL Server当前选择的代码页中不存在的字符-您可以在导入之前去除那些多余的特殊字符吗?如果不是，您可能需要对目标列的数据类型使用 NVARCHAR(MAX)，以便允许它对字符使用Unicode(从而甚至支持输入字符串中最奇特的字符)

Also it seems that "Code" column contains characters that aren't present in your currently selected code page in SQL Server - can you strip those extra special characters before importing? If not, you might need to use NVARCHAR(MAX) for your target column's data type in order to allow it to use Unicode for its characters (thus supporting even the most exotic of characters in your input string).
