Answer 1

Are the seasons defined
considering northern or southern hemisphere?
The
beginning and
end of each season
varies
according to the hemisphere
and even
country.Vide
equinox and
solstice.
Try
-- code #1
;with
Frank as (
SELECT [Date], AAAAMM= Convert(char(6), [Date], 112),
MMDD= Right( Convert(char(8), [Date], 112), 4)
from ...
SELECT [Date],
DateYM= AAAAMM,
Season= case when MMDD >= '0320' and MMDD < '0620' then 'AU'
when MMDD >= '0621' and MMDD < '0922' then 'WI'
when MMDD >= '0923' and MMDD < '1221' then 'SP'
else 'SU' end +
Right('00' + Cast((Year([Date]) % 100) as varchar), 2)
from Frank;
  or
-- code #2
CREATE FUNCTION SeasonYear (@Date date)
returns char(2) as
begin
declare @MMDD char(4), @S char(2);
set @MMDD= Right( Convert(char(8), @Date, 112), 4);
set @S= case when @MMDD >= '0320' and @MMDD < '0620' then 'AU'
when @MMDD >= '0621' and @MMDD < '0922' then 'WI'
when @MMDD >= '0923' and @MMDD < '1221' then 'SP'
else 'SU' end;
return @S;
end;
go
SELECT [Date],
DateYM= Convert(char(6), [Date], 112),
Season= dbo.SeasonYear([Date]) +
Right(Convert(char(4), [Date], 112), 2)
from ...;
