You could do the following:
select cod_var, Year, Month, 1+((ten-1)*10) as Day, RainDay1 as Rain where RainDay1 is not nullunion allselect cod_var,
Year,Month, 2+((ten-1)*10) as Day, RainDay2 as Rain where RainDay2 is not null
..
I'm sure that there is a function that could do this too, but I'd tend to just convert the data and be done with it.
