我创建了一个名为test2如下的表SQL Server 2008 R2

编号 || 用户名 || 时间

tinyint 唯一标识符时间(7)

我创建了一个.csv与以下内容相同的文件，其中包含一行

编号 || 用户名 || 时间(7)

1 b64d51a8-852f-40ea-ab4c-080df747214b 00:00:00

现在，我使用 SQL 导入向导将此行插入到我的数据库表中。

在选择以下映射（见下文）时，我收到此错误：

映射：

id(tinyint) -> SSIS 单字节无符号整数

userid(uniqueidentifier) --> SSIS 唯一标识符

time(7) ---> 精确的 SSIS 数据库时间

谁能告诉我我在这做错了什么？有没有办法解决这个错误？

提前致谢

使用单字节无符号整数作为源数据类型以映射到 tinyint 目标。tinyint 使用 1 个字节的存储空间，其值范围为 0 到 255，因此它是无符号的。
