使用 SSIS 中的脚本任务修改 CSV 文件以添加额外的逗号

Question

我有一个以下格式的 CSV 文件

"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"300","331"
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"700","701

在上面的数据中，我想在使用Flat File Source 读取文件后的第 4 行和最后一行的数值之后添加额外的逗号，在这种情况下，应该在第 4 行和第 4 行添加额外的 6 个逗号最后一行 所以正确的数据应该是这样的

"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"300","331",,,,,,
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"Sometext","Sometext","Sometext","Sometext","Sometext","Sometext","Sometext",
"700","701,,,,,,,

我只需要在数据集中添加逗号而不修改现有文件 这在 SSIS 中如何实现？

一种方法是使用 脚本组件 集作为数据流任务中的源。在下面的文章中找到一个详细的例子，说明它应该包括什么：

这将添加缺失的列，并根据您的第一个标题行忽略任何额外的列。
