I have created a pipeline in Azure Data Factory using the Copy Data functionality.
It is copying a view from Azure SQL to a CSV file on a Blob Storage. I have chosen to Zip the file and name it Output_{year}{month}{day}.zip.
Everything is working perfectly, however the content of the zip file contains the csv which has a GUID for a filename. How can I make it so that the filename inside the zip is: Output_{year}{month}{day}.csv?
For your case, currently there is no option in ADF to customize the file name inside the generated zip file.
One possible trick is you can use two copy activities, the 1st one copy to Output_{year}{month}{day}.csv, the 2nd one copy from that file to Output_{year}{month}{day}.zip with "copyBehavior" set to "PreserveHierarchy" (default).

I have tried Flatten Hierarchy, Merge Files and Preserve Hierarchy in my attempts to Append or Merge files with Data Factory, but it will neither Append or Merge
The Sink looks like the following:
Can someone let me know how to configure Data Factory to merge files please
To merge the files, use the copy activity after the ForEach loop.
First copy the individual files from REST to ADLS folder using the above loop. Then use another copy activity with source (give the datasets folder path).
Use Wildcard path. Here I have used csv for sample.
Now in sink, use merge option.
files with same structure from REST API copied to ADLS folder.
Final csv file after merging.
I'm trying to export multiples .csv files from a blob storage to Azure Data Lake Storage in Parquet format based on a parameter file using ADF -for each to iterate each file in blob and copy activity to copy from src to sink (have tried using metadata and for each activity)
as I'm new on Azure could someone help me please to implement a parameter file that will be used in copy activity.
Thanks a lot
If so. I created simple test:
I have a paramfile contains the file names that will be copied later.
In ADF, we can use Lookup activity to the paramfile.
The dataset is as follows:
The output of Lookup activity is as follows:
In ForEach activity, we should add dynamic content #activity('Lookup1').output.value. It will foreach the ouput array of Lookup activity.
Inside ForEach activity, at source tab we need to select Wildcard file path and add dynamic content #item().Prop_0 in the Wildcard paths.
That's all.
I think you are asking for an idea of ow to loop through multiple files and merge all similar files into one data frame, so you can push it into SQL Server Synapse. Is that right? You can loop through files in a Lake by putting wildcard characters in the path to files that are similar.
Copy Activity pick up only files that have the defined naming pattern—for example, "*2020-02-19.csv" or "???20210219.json".

We are working on a solution of downloading the file posted in share point and movig it to diffrent blob
based on the clinet: xyz,dtf
And her we have same URL below example:
https://ABC.sharepoint.com/teams/ODS/XYZ_Backup/
https://ABC.sharepoint.com/teams/ODS/dtf_Backup/
can we change the folder id and coresponding folder path of blob on fly ,that is parameterize these values for each client something like a lookup table
Also is it possible to change the file name before downloading or after adding a date to it.
I have a set of CSV files stored in Azure Blob Storage. I am reading the files into a database table using the Copy Data task. The Source is set as the folder where the files reside, so it's grabbing it's file and loading it into the database. The issue is that I can't seem to map the file name in order to read it into a column. I'm sure there are more complicated ways to do it, for instance first reading the metadata and then read the files using a loop, but surely the file metadata should be available to use while traversing through the files?
Thanks
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:
I have developed one windows application,which is checking for newly updated or generated file in a directory and copying the data to a temporary file.My application is doing its job perfectly.But,There is one third party application "POS Text Sender",which will read all the text from a temporary file and display on CCTV Camera if i use notepad text editor to copy data.But when my application does this work,POS Text Sender will read the contents from first file and its also trace the updated contents of that file from time to time.Once New file is generated in that directory,as usual,my application will copy the entire contents of that file to temporary file,but POS Text sender will not read that data and then if it has to display any contents,I should restart POS Text Sender.I really dont know how POS Text Sender knows that my application is copying from newly generated file and how to get it stopped.What is the difference between data writing to existing file and copy entire content from another
What is the difference between data writing to an existing file and copying the entire contents from another?
It sounds like maybe the 3rd-party app is looking at either the created or modified date stamp on the files, and not taking both into account. The difference is as follows:
when you create a new file, created and modified will be the same
when you edit an existing file, modified will be later than created
when you copy an existing file, the new file's created will be later than its modified timestamp
