【问题描述】：
我对 SSIS 很陌生。我正在使用 SSIS 2008。我看到有许多工具可以执行与某些 SQL 运算符相同的功能。什么时候应该使用 SSIS 工具与 TSQL 运算符？另外，这里有关于更有效解决方案的任何建议吗？
下面是我从 SSIS 导入/导出向导中选择的 tsql 查询。因此，我目前的解决方案除了一个数据流源和一个数据流目的地外，不使用任何 SSIS 工具。

问题标题中的原始文件是什么意思？此时，您没有在包中使用原始文件。另外，您可以更准确地编辑问题吗？您要解决的问题是什么；到目前为止你做了什么；您遇到了哪些错误/障碍？
-
谢谢。原始文件 = 源文件。你对我的问题有什么不明白的地方？我只是想弄清楚在什么情况下使用 SSIS 函数与 TSQL？我刚刚尝试了上述 TSQL 方法。而且由于这听起来比尝试在 SSIS 中重现相同的逻辑更简单、更有效，因此我可能会改用 TSQL 解决方案。
-
在 SSIS 工具包中，我们有 Raw File Destination 和 Raw File Source。因此，这个问题的标题让我相信除了问题中的其他要点之外，您还遇到了原始文件 SSIS 组件的问题
