I know that this can be done in R but i am vastly more comfortable with SSMS. The issue is that I am converting old excel files into database tables. To do so, demands some interesting manipulation. The excel file is structured as such with each row representing a month
State county1 county2
gamingwin 400 60 65
The desired result in SQL is as such
area year month gamewin
000000 (code for state) 2020 06 (june) 400
000001 (county 1) 2020 06 60
The issue is that this data goes back to 1996 and so for each of the 19 areas, I have to generate (24*12) plus 6. It can be done but hoping to find a way to generate this in a more timely and less error-prone way than copy+paste+manipulate in excel
