SSIS排除Foreach循环容器中的某些文件 [英] SSIS Exclude certain files in Foreach Loop Container

问题描述

我有一个SSIS软件包，可以使用表达式和通配符从特定目录加载csv文件，以提取所有文件.

I have a SSIS package that loads csv files from a particular directory, using an expression and a wildcard for picking up all the files.

当前，容器的FileSpec查找具有以下格式的所有文件:

Currently, the FileSpec of the container looks for all files with the following format:

fileName_environment _ *

fileName_environment_*

，并且工作正常.现在从同一目录中加载第二组文件，为了区别这些文件，文件格式为:

and this is working fine. A second set of files are now bing loaded from the same directory, and to distinguish these, the file format is:

fileName_environment_business _ *

fileName_environment_business_*

因此，第二个SSIS包仅拾取新文件，因为文件的结构如下所示:

So, the second SSIS package picks up only the new files since the structure of the files will look like:

filename_environment_abc 
filename_environment_def
filename_environment_xyz 
filename_environment_business_abc
filename_environment_business_def 
filename_environment_business_xyz

但是第一个包将处理所有文件.

but the first package will process all files.

所以，问题是，我可以设置第一个SSIS包的FileSpec来忽略以下格式的文件吗?

So, the question is, can I set the FileSpec of the first SSIS package to ignore the files which are in the format:

fileName_environment_business _ *

fileName_environment_business_*

推荐答案

在foreach循环容器中，将虚拟Script task放在您已经获得的第一个块之前.用一条线连接这两个，并将Constraint Options设置为expression，在其中应定义一个FINDSTRING函数:

In the foreach loop container put a dummy Script task before the first block you've got already. Connect those two with a line and set Constraint Options to expression, in which you should define a FINDSTRING function:

FINDSTRING(@var, "business", 1) == 0

@var是可迭代的循环.

Where @var is the loop iterable.

仅内部没有业务"的文件将继续进行下一步.希望这就是您想要的.

Only files without "business" inside will proceed to the next step. Hope this is what you wanted.
