SQL SSIS issue: How to Process multiple files with different names

Greetings Experts,

I have a 2 questions that I need help with.
First, I have this SSIS package that takes an Excel file (enrollment.xls) from a server share and imports it into a SQL database, then it deletes it from the server share.  The idea is that someone will create this enrollment.xls file and place it on the server share to be processed.  However, the problem with this approach is that there can only be one file in that location at any given time.  How do I go about programming the SSIS package to look for every file in the folder and process each?  The file does not need to be called enrollment.xls.... it can enrollment1.xls, enrollmentB.xls.   This way people can pop as many files in there to be processed and I can then schedule this SSIS package to run at night.

Dear friend,
You need to use ForEach Loop to read each file type inside a specific filesystem path.
Check the example I made in other question:

If you have some doubts I can customize it for you!
regards!

Hi PedroCGD,

I looked at your example in the other post and I sort of understand.    I get the general idea, but I am not sure how to change the data flow to do what I want it to.   I have attached the SSIS I created...be gentle this is my first complex package.

In this package it does a number of things.  This is what happens.
1.  An XLS file is imported into a staging database table.  This file is specfic to one Study so a column called Study  will contain URT456.
2. The stage table is compared to another table, and all records are deleted from the second table where Study = Study.  
3.  The stage table is copied to second table
4.  The stage table is truncated
5. The orginal file is deleted.

The problem is the orginal XLS will be called different things so my code will not work.  Also the XLS will have different studies.  I have attached 2 XLS examples.  

I think if i can get this ForEach loop working it will solve my problem.  I just cant figure out how to determine the name of the XLS file if it isnt hardcoded.
Update-Enrollment-Table-dtsx.txt
EnrollmentTable-INOT11.xls
EnrollmentTable-URT456.xls

What Kind of Coding Program is Right for You?

There are many ways to learn to code these days. From coding bootcamps like Flatiron School to online courses to totally free beginner resources. The best way to learn to code depends on many factors, but the most important one is you. See what course is best for you.

The for each loop returns the name of each file that it finds. That saves you having to hard code anything.
Read through this and see if it helps:

.. oh and you should truncate the staging table at the very start not at the end for two reasons:
-If your package fails in the middle, it will leave data in the staging table which will confuse things for the next run
-Yuo can inspect the staging table afterwards to help debug if need be.

Thanks for the reference.  I looked at the documentation you sent and I was able to get it working with csv files (using flat file connection), but when I try to use an excel connection I get errors.  It seems as soon as I enter the expression for the excel connection manager i get errors when i run the package.

Any ideas?

How about this one:

(If this solves your problem then you should assign points to Pedro and then google.com in that order   :)  )

attached snippet is an interesting example, it does do the for loop and is using file names, but only the first bit is relevant - it then does a t-sql equivelent, and a dos command equivelent, so do not read too far :)

No, I actually resolve and closed the question...i totally forgot about this one though...I will close it now.  I used a combination of all your advice so I will split it three ways.  I dont generally like opening a second question but this was something that cant wait.
