Dataflow sink table as a source

Mogale Rickie 0

I am trying to add the sink as source in order to implement exist and lookup for SCD Type 2 but the source table (from the sink) is blank no column names or data, does anyone perhaps know why that is? How can I resolve this?

You didn't provide information about your datasource or the dataflow you are having, just verify if the data is being successfully written to the sink table. Sometimes the configuration or permissions might prevent data from being written, or the write operation may be delayed.

If the schema and data are there, but not immediately visible, there could be a caching issue or a delay in the data refresh in the source system.

Thank you for the response, however I can preview the data on the sink and its available, I can even query it in SQL and it has data; only when I use the (sink) table as a source where it comes out empty. They from a blob storage container

The sink is the location/data store, where we would like the data to be loaded to. If you are familiar with SSIS Data Flow Task, this is similar to the Destination component.

So did you run your pipeline before ?

You may try to delete the sink and add it afresh, to let go of any cache issue.
