Adding an "Activity_Date" to a nightly refresh dataset.
I just set up a connection for a dataset that doesn't have any fixed 'date' column. The only date column it will have will be the batch_last_run date. On a nightly basis this dataset will append and start to build history. How can I add a new date column in a format such as 'Jul 1, 2021', so that the new data and old data have a correlating date?
