Hi @Anthony Jones ,
Welcome to Microsoft Q&A forum and thanks for reaching out here.
As per my repro, I was able to see all the columns of my Temporal Table in Projection
section of the Data flow source transformation.
Also when I do data preview using a query to get the values that were actual (current) at the specified point in time in the past, the data preview returns a table with a rows containing the values that were actual (current) at the specified point in time in the past.
Here is my source data in Azure SQL table and it's history for reference:
In the above sample you have shared for TTable, I don't see ValidFrom
and ValidTo
columns, which could be the reason you are not seeing them while doing projection in Dataflow.
Hence I would recommend you to please review these docs related to temporal tables and cross check if your temporal tables have been created accordingly.
- Temporal tables
- Getting started with temporal tables in Azure SQL Database and Azure SQL Managed Instance
As per my repro, I don't see an issue with ADF dataflow handling temporal table.
Hope this helps. Do let us know if you have further query.
