Add column with the name of the source

[Experteam]

Hello everyone, How to add a custom column with the name of the source file? I have the date in the name of the source and I want to keep it because it's my only time stamp. 

Thank !!

@Experteam - You could do the following:

1. Create a parameter - This will be a date

2. Use the parameter as part of the name of the file to load.

3. Add the custom column, and set the value to the parameer.

4. Create a function out of your query

5. Create a list of file dates

6. With the list, invoke your function, then expand the list. You will then have all of your files loaded, each with the specified date in a column.
