I need to get records of last 2 months and last month(last year) based on my table field paidDate, using SQL server 2016. 

Suppose, I run the query on Feb 1st/2nd, 2020. I need the monthly data from December 2019, January 2020, as well as January 2019. 

What's the SQL query for this? Is it possible to club all of these scenario into one?
