around this issue I am looking at the link below. ,
I would like to loop through months any days
    @{concat(formatDateTime(adddays(utcnow(),-1),'yyyy'),'/',string(pipeline().parameters.month),'/',string(pipeline().parameters.day),'/*')}

where:
    The path will become as: current-yyyy/month-passed/day-passed/* (the * will take any folder on one level)

Azure data factory (ADFv2) - how to process multiple input files from different folder in a USQL job


Tag : azure , By : Guyou
Date : March 29 2020, 07:55 AM
this will help yes there is. You should use Virtual columns. Example: Your file has only column1 and column2.
path1=/yourFolder/2018/11/1/file.csv
DECLARE date1 = new DateTime(2018,11,1);
DECLARE date2 = new DateTime(2018,10,25);
@inputData = EXTRACT column1 string,
column2 string, 
FileDate DateTime //this is virtual column
FROM "/yourFolder/{FileDate:yyyy}/{FileDate:MM}/{FileDate:dd}/file.csv"
USING Extractors.Text(delimiter:';',skipFirstNRows:1);
@res = SELECT * FROM @inputData WHERE FileDate == date1 AND FileDate ==date2;

will help you Just a thought - I don't see your dataset definition but...
Should you pass in path and file name to the dataset as parameters?

Azure Data Factory - Recording file name when reading all files in folder from Azure Blob Storage

Hope that helps This is not possible in a regular copy activity. Mapping Data Flows has this possibility, it's still in preview, but maybe it can help you out. If you check the documentation, you find an option to specify a column to store file name.
It looks like this:

Find the number of files available in Azure data lake directory using azure data factory


Tag : development , By : pjkinney

Hope this helps Since the output of a child_items Get Metadata activity is a list of objects, why not just get the length of this list?
@{length(activity('Get Metadata1').output.childItems)}
