I am needing to extract three months at a time of one year for years 2016-2020. For example I need Jan-March in one file, Apr-Jun in another, etc. for each year.
The beginning of my SQL looks like so but I need it to go through years 2016-2020, extracting data three months at time.
DECLARE @StartDateKey int = 20160101,
@EndDateKey int = 20160331;
