This will help us loop thru each lookup file. Learn ssis - In this guide you can find out steps to load multiple CSV/TXT files from a folder to the database table.Parameter/VaiableDetailsSourceFolderIt.While working on a recent project for a customer that involved importing both Excel 97-2003 and Excel 2007/2010 files, I was a little surprised to discover that the Foreach Loop File Enumerator will return both *.xls and *.xlsx files even if you only specify to return *.xls files.A 'Foreach Loop' container has been created with 'variable Enumerator'. Give each columns to suitable. Step 5 : its most important step.
The file names read by the Foreach Loop Container are being assigned to a user variable called varFileName. During my testing, I created three files:See the screenshot of the three test files created below:Next, I created an SSIS Package with a Foreach Loop Container with Foreach File Enumerator as the enumerator type and specified *.txt as the file mask. Txt (ECHO xyz.I tested this behaviour with similar results with other file formats as well. Double-click the modified batch file to execute the SSIS package. So when you run this package, it is expected to search for files with many extensions and print the full path and name.The batch command ASSOC associates a file extension with a file type.
I assume then, that the Foreach Loop file enumeration behaviour may be bound to the D.O.S. If we specify *.txt or *.txt*. The two commands executed are shown below along with the results:Interestingly, we get the same result in D.O.S. To see the results of both masks. As an additional test, I executed the command in D.O.S. This means, that specifying *.txt or *.xls is the same as specifying *.txt* or *.xls*.

Xlsx”.So, if you require to only limit your control flow execution for files with a specific extension, as in Douglas’ example. The blog post where he mentions this as a gotcha can be found here: There appears to be no way to specify, “Give me. For the command.The only reference I found regarding this issue with SSIS and the For Each Loop Container was by Douglas Laudenschlager ( Blog), technical writer for Microsoft on the SQL Server Integration Services documentation team. With the introduction of support for more than three letter extensions, this little issue might have been overlooked in D.O.S. On my Windows 7 machine is. The current version of D.O.S.
Once you capture the file extension in a variable, you can use a precedence constraint to restrict further control fow task execution for files of a specific file extension.
