Hey guys.
Thank you for your assistance so far.
Essentially, we have a large amount of files that accumulate interest on a daily basis. The interest is calculated within 365 Dynamics based on the information on file, then that interest information is added to a dataverse table.
That information needs to be fed back into an Azure SQL database so that when payments are made against those files, each interest item gets paid off and updated to reflect the change. A dataflow can handle the update back to the dataverse, but getting the information out of the dataverse is the hard bit (since Microsoft have neglected to make anything that goes the other way).
I really need two solutions, one to copy all of the existing information from the database into SQL (over 1m rows) as a one-off ingestion process, and a daily process that just inserts the delta.
