从数据流列插入数据可能会出现SSIS Truncation
SSIS Truncation may occur due to inserting data from data flow column
我在 SSIS 中构建了 Foreach 循环容器，它从目录中的多个 excel (*.xlsm) 文件中提取数据，然后将结果写入另一个位置。
[最终 BCS 描述] 给我带来了问题。我尝试使用数据转换 DT_WSTR.
我遇到错误：
Truncation may occur due to inserting data from data flow column
"Copy of Final BSC Description" with a length of 2000 to database
column "Final BSC Description" with a length of 255.
这没有意义。源中的“最终 BSC 说明”大于 255，并且目标中没有上限。有人能提供解决方案或解决方法吗？
错误信息如下。

我不知道为什么会出现这种情况，但必须匹配字段的长度我主要使用派生列并设置表达式来更改字符串的长度
找到解决方法。从 Advanced Editor for Excel Source 将数据类型更改为 Unicode string [DT_WSTR] Length = 2000
在目标 excel 文件的“最终 BSC 说明”单元格中，添加长度大于 255 个字符的虚拟值。然后隐藏整行。
