SSIS包：在unicode和非unicode字符串数据类型之间进行转换
我正在连接到Oracle数据库并且连接正常，但是我的某些列出现以下错误：
Description: Column "RESOURCE_NAME" cannot convert between unicode
and non-unicode string data types.
RESOURCE_NAME的值：
- 对于Oracle：
VARCHAR2(200 BYTE) - 对于SQL Server：
VARCHAR(200 BYTE)
我可以通过Oracle SQL Developer连接到Oracle数据库而不会出现任何问题。另外，我有SSIS包设置Run64BitRuntime = False。
8 个答案:
答案 0 :(得分：11)
Oracle数据类型VARCHAR2似乎等同于SQL Server中的NVARCHAR或SSIS中的DT_WSTR。 Reference
您必须使用SQL Server中的 数据转换转换 或CAST或CONVERT函数进行转换。

如果包装在一台机器上工作而在另一台机器上不工作;尝试将NLS_LANG设置为正确的语言，区域和字符集并测试包。
[Command Prompt]> set NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
答案 2 :(得分：2)
最简单的方法是在记事本（dtsx文件）中打开SSIS包并对 validateExternalMetadata =“True”的所有实例进行全局查找和替换 validateExternalMetadata =“False”。
注意：我们在通过SSIS连接到Linux上的Oracle 11g数据库时遇到此问题。

。如果SSIS仍然因为元数据而给你一个错误。以下是解决问题的方法。
- 打开高级编辑器。
- 在“输入和输出”属性下，展开“源输出”。
- 展开输出列
- 选择导致问题的列。
- 转到数据类型属性并将数据类型更改为所需类型DT_STR，DT_Text等。
答案 5 :(得分：0)
如果一切都从上面失败了。创建一个表变量并将数据插入其中。然后选择所有记录作为源。在脚本中使用SET NOCOUNT ON。
答案 6 :(得分：0)
您只需双击数据流中的“数据转换”块，然后将其更改为“ Unicode字符串[DT_WSTR]”

答案 7 :(得分：0)
即使使用SQL Server而不是Oracle，我也遇到了非常相似的问题。就我而言，我使用平面文件作为数据源，因此我进入了平面文件连接管理器并手动将列类型更改为Unicode字符串：
我不知道这是否可以解决您的问题，但这对我有所帮助-希望其他人也能得到帮助。 （我受this previous answer to this question BTW的启发而尝试，只是为了在应得的信用额中给予信用）。
