![]() ![]() ![]() In this design, the data flow is contained within the foreach container, which will execute the contents of that data flow task once for each file found in the specified directory.Īs shown above, the foreach loop (indicated with the naming convention prefix FELC) contains only one task, the data flow (prefaced with DFT) that will be used to load the data files. For this to work, all of the files would need to reside in the same directory structure (either locally or on the network), and they must all have the same structure and metadata. ![]() The SSIS foreach loop is configured to allow you to easily ingest multiple data files in a single data flow task. Processing multiple files in SSIS with the foreach loop The foreach loop container will execute its contents from zero to times, with being the number of items inventoried when the foreach loop starts its execution. That list could be a static list of items coded at design time, rows in a result set, nodes in an XML file, or of interest in this blog post, a list of files in a directory. The foreach loop container is used to iterate through a discrete list of items at runtime. In this post, I will briefly show a more commonly used alternative approach for processing multiple data files: the foreach loop container. Yesterday I wrote about the little-known but still useful multiple flat file connection manager. ![]()
