Question

我在test2

中创建了一个名为SQL Server 2008 R2的表，如下所示

id || userid ||时间

tinyint uniqueidentifier time（7）

我创建了一个.csv文件，其内容如下，包含一行

id || userid ||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。

在选择以下映射时（见下文），我收到此错误：

映射：

id（tinyint） - ＆gt; SSIS单字节unsigned int

userid（uniqueidentifier） - ＆gt; SSIS唯一标识符

时间（7）---＆gt;精确的SSIS数据库时间

任何人都能告诉我这件事我做错了吗？有没有办法解决这个错误？

提前致谢

Answer 1

使用单字节无符号整数作为源数据类型映射到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。

SQL导入向导无法映射tinyint
